[Object of the Invention] The present invention relates to a paint for preventing wood cracking that has excellent crack preventing effects and stability over time. [Industrial application field] Used to prevent cracks in wood products such as raw wood and processed logs, square posts, cylinders, etc. [Prior Art] A method has been adopted in which a conjugated diene-aromatic monoolefin copolymer latex is applied to the surface of wood to prevent cracking. (Tokuko Showa 57-60922
From the claims, the same publication states, "28 to 70% by weight of aliphatic conjugated diolefins, 30 to 72% by weight of alkenyl aromatic monomers, and other monoolefins that can be copolymerized with these. A composition layer comprising as a main film-forming component a copolymer containing 0 to 42% by weight of a monomer and having a gel content of 0.3% by weight or more after film formation. Split-prevented wood.'' [Problems to be solved by the present invention] However, the above method has poor stability over time;
The copolymer latex film deteriorates when exposed outdoors for a long period of time, making it impossible to obtain sufficient crack prevention effects. [Structure of the present invention] The present invention comprises 10 to 70% by weight of a conjugated diolefin monomer, an ester of an ethylenically unsaturated carboxylic acid,
~70% by weight, ethylenically unsaturated carboxylic acid 0-20
A copolymer consisting of 5 to 28% by weight of an aromatic monoolefin monomer, 0 to 20% by weight of a vinyl cyanide monomer, and 0 to 39% by weight of a monoolefin monomer copolymerizable with these. This is a paint for preventing wood cracking, characterized in that it contains 0.5 to 2.0 parts by weight of a compound having a polyalkylene oxide group based on 100 parts by weight (solid content) of a polymer latex. As the conjugated diolefin monomer, butadiene, isoprene, chloroprene, etc. can be used.
Particularly suitable is butadiene. These monomers are used at 10-70% by weight,
If it is less than 10% by weight, the crack prevention effect will be poor. Moreover, if it exceeds 70% by weight, stability over time will be poor. Examples of esters of ethylenically unsaturated carboxylic acids include methyl acrylate, ethyl acrylate, butyl acrylate, methyl methacrylate, ethyl methacrylate, 2-ethylhexyl acrylate, 2-hydroxyethyl acrylate, and glycidyl methacrylate. . These monomers are used in an amount of 3 to 70% by weight, but if the amount is less than 3% by weight, stability over time is poor. Moreover, if it exceeds 70% by weight, the crack prevention effect will be poor. As an ethylenically unsaturated carboxylic acid monomer,
Examples include acrylic acid, methacrylic acid, itaconic acid, fumaric acid, maleic acid, crotonic acid and dicarboxylic acid anhydrides. These monomers are 0
It is used at ~20% by weight, but if it exceeds 20% by weight, the viscosity stability of the paint will be poor. Examples of the aromatic monoolefin monomer include styrene and α-methylstyrene. These monomers are used in an amount of 5 to 28% by weight, but outside this range the stability over time tends to be poor and is not preferred. Examples of vinyl cyanide monomers include acrylonitrile and methacrylonitrile. These monomers are used in amounts of 0 to 20% by weight. Monoolefin monomers that can be copolymerized with these include ethylenically unsaturated carboxylic acid amide monomers such as acrylamide, methacrylamide, N-methylolacrylamide, and glycidylmethacrylamide, vinyl chloride, and vinyl acetate. vinyl monomers. These monomers are used in an amount of 0 to 39% by weight, but if it exceeds 39% by weight, the crack prevention effect is poor. These monomers may be used alone or in combination of two or more. Examples of compounds having a polyalkylene oxide group used in the present invention include polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene alkyl ether sulfate, polyoxyethylene alkyl phenyl ether sulfate, polyethylene glycol , polypropylene glycol, poly(oxyethylene/oxypropylene) glycol monoether, polyoxyethylene polyoxypropylene block polymer, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyoxyethylene fatty amine, propylene glycol fatty acid ester, etc. can be given. These compounds are used in an amount of 0.5 to 20 parts by weight, but if less than 0.5 parts by weight, the crack prevention effect is poor.
If it exceeds 20 parts by weight, stability over time will be poor. These compounds may be used alone or in combination of two or more. The paint of the present invention contains general fillers such as heavy calcium carbonate, precipitated calcium carbonate, clay aluminum hydroxide, magnesium hydroxide, carbon black, etc. in an amount of 200 parts by weight or less per 100 parts by weight (solid content) of the paint. Can be used together. Furthermore, various thickeners such as methylcellulose, carboxylated methylcellulose, polyvinyl alcohol, and polyacrylates, natural polymer binders such as casein and starch, and melamine
Waterproofing agents such as formalin resin, urea-formalin resin, and polyamide resin, as well as various additives such as dispersants, antiaging agents, bactericidal agents, and antifungal agents can also be used in combination. The present invention will be specifically explained below using examples, but the present invention is not limited thereto. All parts in this example mean parts by weight unless otherwise specified. Example 1 Production of copolymer latex Each monomer in the parts shown in Table 1, 0.5 part of t-dodecyl mercaptan, 1.2 parts of sodium alkylbenzenesulfonate, 0.5 part of sodium sulfur, and ammonium persulfate.
Pour 0.8 parts and 100 parts of water into 10 autoclaves.
Polymerization was carried out at 65°C with stirring. The obtained copolymer latexes are designated as A to K, respectively.
