DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of fire protection putty, and in particular,
This invention relates to a fireproof putty that can form a strong carbonized heat insulating layer and exhibit perfect fire resistance and sealing properties.

Conventionally, it has been common practice to maintain sealing properties by filling putty into the gap between a window glass and a crosspiece.

Such putty is usually obtained by kneading inorganic powder with a curable liquid color vehicle. However, in such conventional putty, if the organic material part burns in the event of a fire, the volume shrinks and the sealing effect is lost, and at the same time, the binding effect of the inorganic powder is also lost, making it extremely brittle. There was a problem.

On the other hand, in recent years, fire-retardant paint has been applied to the cable surface to impart fire resistance to installed cables, but it is extremely difficult to apply fire-retardant paint to wall penetrations, and sealing Since the effectiveness is far from perfect, there has been a strong desire to develop a putty with fire resistance comparable to that of fire-retardant paints that can be applied to these areas.

The present invention has been made to solve these conventional difficulties, and consists of 100 parts by weight of a viscous liquid organic polymer material containing at least 20% by weight of epoxidized-1,2-polybutadiene, and 40 to 40 parts by weight of an inorganic filler. 200 parts by weight as the main ingredient,

~35,000CPS, specific gravity (304C) 0.989,
It is a slightly yellow, viscous liquid with an oxirane oxygen content of 7.5 to 8.070, and is a polyolefin obtained by epoxidizing atactic 1,2-polybutadiene.

This eboxidized-1,2-polybutadiene has polyamines,
It is cured by curing agents such as acid anhydrides, Lewis acids, polyphenols, and polymercaptans, and it also has a reactive vinyl group, so it reacts with other components at high temperatures and hardens the putty. In the present invention, the above-mentioned epoxidation-

However, even when such other liquid polymeric substances are used, it is necessary to use epoxidized 1,2-polybutadiene, which accounts for at least 20% by weight of the entire viscous liquid polymeric substance. The reason why the weight is 20 and 70 or more is because the softness becomes low and becomes too hard to withstand use. In addition, the inorganic fillers used in the present invention include aluminum hydroxide, talc, clay, charcoal,
Examples include short asbestos fibers, talc treated with silane coupling, clay, aminosilane, and kaolin grafted with mercaptosilane.

Among these inorganic fillers, aluminum hydroxide is
The heat of a fire releases bound water and prevents the temperature of the paint film from rising. Kaolin grafted with aminosilane and mercaptosilane is carbonized by the heat of a fire, forming a strong carbonized heat insulating layer. It is particularly suitable for the present invention. Further, the carbonized layer forming agent used in the present invention includes phenolic resin, urea resin, starch, etc., but it is not necessary to specifically blend it when a silane-coupled filler is used.

Furthermore, the flame retardants used in the present invention include known antimony trioxide, halogen-based, and bromine-based flame retardants.

In addition, the softness of the composition is 5.0 to 1 with the above ingredients.
If it is difficult to adjust the thickness to 2.0 mm, a plasticizer may be added as appropriate.

Examples of such plasticizers include silicone oil,
Flame retardant plasticizers such as tricresyl phosphate (TCP) are suitable. Furthermore, in the present invention, a vitreous film forming agent such as glass beads, a borate compound such as zinc borate, or barium borate may be blended.

In the present invention, the blending amount of each component is limited as described above because if the blending amount of the inorganic filler is less than 40 parts by weight, other additives must be added to obtain a softness of 50'Mll or higher. This is because it is necessary to increase the blending amount, which increases the cost and is uneconomical, and it also tends to flow at high temperatures.
This is because if it exceeds 200 parts by weight, the softness becomes too high and construction becomes difficult. Further, it is desirable that the total amount of the carbonized layer forming agent, vitreous film forming agent, flame retardant, etc. is equal to or less than the amount of the main agent.

If the amount exceeds the amount of the main ingredient, the softness will increase and the cost will increase, which is not preferable. Note that, if necessary, the putty of the present invention may contain pigments, anti-aging agents, and other known additives. In the fire prevention putty of the present invention constructed as described above, the epoxidized 1,2-polybutadiene reacts and hardens when heated during a fire, preventing the putty from softening and being washed away, and further preventing the fire from progressing. It forms an insulating carbonized layer and acts to block the spread of fire heat. In particular, in the present invention, when a vitreous film forming agent is blended, the forming agent melts upon heating to form a vitreous film, strengthens the carbonized layer, prevents its collapse, and improves airtightness. be effective.

The properties of the resulting putty were as shown in Table 2 below. In Table 2, Comparative Examples 1, 2, and 5 have oxygen index, presence or absence of shape change,
The reason why there is no description of good/poor workability, pass/fail for flame retardancy, and strength after combustion is because the softness was too small to be a subject of judgment.

As is clear from this table, among the viscous liquid organic polymer substances, eboxidized-1,2-polybutadiene is 20% by weight 7
Comparative Examples 1 and 2 with less than 0 did not have good softness and therefore did not function as putty, and other viscous liquid organic polymer substances were used without using eboxidized-1,2-polybutadiene at all. In Comparative Examples 3 and 4, softness, oxygen index, workability,
Although the flame retardant properties were satisfied, in the heating softening test, softening occurred early, making it unusable for practical use. Furthermore, Comparative Example 5 had the disadvantage that good softness could not be obtained. was.
