TITLE OF THE INVENTION A cleaning resin composition BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a cleaning resin composition used for cleaning the inside of various molding machines. More particularly it relates to a cleaning resin composition obtained by blending a neutral salt o of an alkylbenzenesulfonic acid, an inorganic filler °and a water-repellent compound with a polyolefin resin; 000004 o 0, 2. Description of the Related Art Recent molding of thermoplastic resins has been Ott more and more diversified and production of more grades- 00 in smaller quantities has been intended. Further, due to appearance of engineering plastics, etc., color 0exchange or resin exchange inside molding machines has been carried out within a broad temperature region, a and the frequency of the color exchange or resin 20 exchange has also been increasing.
Heretofore, at the time of such color exchange or resin exchange, in order to remove contaminants caused by the preceding resin inside the molding machine i.e. in order to clean the inside of the molding machine, the following processes have been employed: 2 a process of drawing out the contaminated screw inside the molding machine, followed by scraping off the contaminants on the screw or the inner wall of the cylinder by means of a brush or the like i.e. the so-called hand sweeping, or a process of flowing a colorless resin (hereinafter abbreviated to cleaning resin) through the inside of the cylinder to clean the screw together with the cylinder (hereinafter referred to as co-cleaning) without drawing out the 10 screw.
0 0e 00 s ,However, such processes require a long time for 0 °1 completely cleaning the screw and the inside of the S* cylinder, and in the case of the co-cleaning, a large quantity of cleaning resins is used to cause a large °0 15 loss in the economical aspect.
Thus, in order to solve such problems, a cleaning agent composed mainly of a hard resin such as acrylic resins, a cleaning agent obtained by blending a nonionic surfactant with a thermoplastic resin, a cleaning agent obtained by blending a lubricant such as stearic acid with a thermoplastic resin, etc. have been developed.
However, in the former case, since the acrylic resins have high melt viscosity, a high load is applied at the time of cleaning the inside of the molding machine and also it is necessary to raise the temperature of the molding machine up to a considerably high 3 temperature, there is a drawback that the resins are susceptible to thermal decomposition.
Further, there are drawbacks that operations are troublesome and require a considerably long time, for example, before the cleaning agent is used, the die screen pack, etc. of the molding machine should be removed, and further if the cleaning agent remains inside the molding machine after completion of the cleaning, the remaining cleaning agent mixes in the 1 0 molded product of the succeeding resin so that the agent in the form of a foreign matter deteriorates the appearance or the physical properties of the molded product.
On the other hand, in the latter case, the cleaning agent obtained by blending stearic acid or the like with a thermoplastic resin is insufficient in the cleaning effect inside the molding machine, and in the case of the cleaning agent obtained by blending a nonionic surfactant with a t]ermoplastic resin, if the service temperature of the cleaning agent exceeds 250'C, vigorous evolution of decomposition gas occurs and also a characteristic odor occurs to have a bad influence upon the operational environment, and further the cleaning effect is insufficient with such a cleaning agent.

The present inventors have made extensive research in order to obtain a cleaning resin composition by the use of which it is possible to effect color exchange inside various molding machines by exchanging the composition for the preceding colored resin or to clean the inside of the machines or to effect resin exchange for the preceding resin inside the machines, in a small quantity of the composition, in a simple operation and in a short time.
10 As a result we have found that a composition obtained by blending a neutral salt of an alkylbenzene- C(s A-pAeFA sulfonic acid, an inorganic filler and a water-repellent compound with a polyolefin resin is a cleaning resin composition capable of solving the above-mentioned problems and have achieved the present invention based on this finding.
SUMMARY OF THE INVENTION T-e ren+i o nnn rps'Pc in the fo11nwni constitutions: a cleaning resi composition comprising a polyolefin resin and a neu al salt of an alkylbenzene- Cc"s Aeoe)\ sulfonic acid, an inorgani filler and a waterrepellent compound blended wit said polyolefin resin Cleaning r-o ito of seardiid tt ±sal L (t) wherein the proportions of said neutr salt of -k-ye-e e a fi I i t -I ~Ci 4a The present invention, therefore, provides a cleaning resin composition comprising a polyolefin resin and 1 to 20 by weight of a neutral salt of an alkylbenzenesulfonic acid, to 30 by weight of an inorganic filler selected from the group consisting of calcium carbonate, talc, magnesium silicate and alumina and 0.5 to 10 by weight of a waterrepellent compound each blended with said polyolefin resin, based on the weight of said the composition.

Among these, preferred resins are high density polyethylene, linear low density polyethylene, crystalline propylene homopolymer, crystalline propylene-ethylene copolymer, crystalline propylene-ethylene-butene-1 terpolymer and mixtures of the foregoing.
1i, d 6,*1 r- 6 As the neutral salt of an alkylbenzenesulfonic acid used in the present invention, sodium salt of an alkylbenzenesulfonic acid is preferably used. This sodium salt of an alkylbenzenesulfonic acid is.one kind of anionic surfactants and its decomposition-initiation temperature is as high as 300 0 C. Examples of suitable alkyl groups for the neutral salt of an alkyl benzenesulfonic acid include linear or branched alkyl groups of
C
8 to C 20 I10 Thus, the surfactant displays a powerful effect upon cleaning of the inside molding machines even within a high temperature region; thus a superior cleaning ooette effect is exhibited over from a low temperature region to a high temperature region.
The quantity of the neutral salt of an aikylbenzenesulfonic acid blended is preferably 1 to 20% by weight, more preferably 5 to 15% by weight based on the weight 00 It 0 of the composition. If the quantity thereof blended is less than 1% by weight, the cleaning effect is small when the inside of molding machines is cleaned with I, the resulting composition, while if it exceeds 20% by weight, notable foaming occurs when the resulting composition is granulated.

and display a notably excellent cleaning effect.
The cleaning resin composition of the present Sinvention has a notably excellent cleaning effect at o ~10 the time of color exchange of the preceding colored resin in various molding machines and also at the time 04 04 of cleaning for exchange of the preceding resin.
Namely, by using the cleaning resin composition o.4 of the present invention in a small quantity or by using the composition in a small quantity together with a cleaning resin, it is possible to far reduce the quantity of cleaning resins consumed and also notably shorten the cleaning period of time, as compared with the case where the inside of molding machines has so far been cleaned by exchange with cleaning resins each color exchange.
Such effect will be illustrated by cleaning of the inside of an injection molding machine. As seen from comparison of use of the cleaning resin composition of the present invention with use of cleaning f :q 17 resins alone, it is possible to reduce the quantity of the cleaning resins required down to about 1/5 1/10 and also to shorten the cleaning period of time down to about 1/5 0 Further, the cleaning resin composition of the present invention displays a notably excellent effect at the time of color exchange and also at the time of resin exchange even in the case where engineering plastics such as modified PPO resin, polyphenylene 1 0 sulfide resin, etc. as the preceding resin are molded S, at high temperatures.
