Problems solved by technology

Not only does it not have the ability to prevent termites and insects, but also its disadvantages are that the drug is easy to lose and the duration of the drug effect is short; the drug is harmful to the human body and pollutes the environment; after the solution of the drug is applied to the wood surface, the effect of painting on the wood surface is affected
Therefore, the current anti-termite and anti-insect spraying technology for wood or planks cannot be applied to the coating and home decoration of modern wooden furniture.

Embodiment 1

[0025] Main agent: (parts by weight)

[0026] ①A-50 (trimer of toluene diisocyanate) 45 parts, ②55 parts butyl acetate

[0027] Hardener:

[0028] ①30 parts of alkyd resin, ②22 parts of butyl acetate, ③3 parts of zinc stearate, ④2 parts of pyrethroid deltamethrin, ⑤3 parts of organic bentonite, ⑥40 parts of 1000 mesh talc.

[0029] Each component of the main agent and each component of the curing agent are separately mixed and dispersed uniformly to obtain the two-component two-component polyurethane anti-termite and insect-resistant putty. When used, the weight ratio of the main agent and the curing agent is Mix it in a ratio of 0.3 to 1, and coat it on wooden products. The method of GB / T 18260-2000 "Test Method for Toxicity of Wood Preservatives on Termites" is used for testing. The quality technical indicators and harmful substance content are as follows:

[0030]

[0031]

[0032] Note: Level 0 means the best performance, level 1 second, and level 5 the worst.

Embodiment 2

[0034] Main agent:

[0035] ①45 parts of L-75 (TDI-TMP adduct), ②55 parts of butyl acetate

[0036] Hardener

[0037] ①35 parts of alkyd resin, ②20 parts of butyl acetate, ③6 parts of zinc stearate, ④2 parts of pyrethroid tetradeltamethrin, ⑤2 parts of organic bentonite, ⑥35 parts of 1000 mesh talc.

[0038] The preparation method and construction method are the same as in Example 1, but the mixing ratio of the main agent and the curing agent is 0.3-1:1. The method of GB / T 18260-2000 "Test Method for Toxic Effect of Wood Preservatives on Termites" is used for testing. The quality and technical indicators and the content of harmful substances are as follows:

[0039]

[0040]

[0041] Note: Level 0 means the best performance, level 1 second, and level 5 the worst.

Abstract

This invention discloses a two-group of polyurethane termite-proof and bug-proof putty. The filming matter, special bug-proof agent, coating auxiliary agent, quartz powder, talcum powder, disintagrated chalk, curing agent in the receipt are used in painting dressing process of furniture and plank floor to form termite and bug-proof putty film to prevent termite and other bristletail to erode carpentry. Its efficiency is high, decorating effect is good, and execution is convenient, it can be used to carpentry processing of modern wood furniture painting and home decorating.

Description

Technical field [0001] The invention relates to a solvent-type wood coating, in particular to a two-component polyurethane anti-termite and insect-proof putty. Background technique [0002] At present, wood termite and insect prevention treatments are mainly based on soaking and painting methods, that is, soaking the wood in a solution containing drugs, or painting a solution containing drugs on the surface of the wood. Such as Chinese patent) low temperature and room temperature quick-drying putty, 93107061.9 and the technology disclosed in the document "MA series transparent wood primer and putty ("New Building Materials", 2002, 2)". Not only does it not have the ability to prevent termites and insects, but its disadvantages are that the medicine is easy to lose and the effect of the medicine is short; the medicine is harmful to the human body and pollutes the environment; after the wood surface is coated with the medicine solution, the paint effect on the wood surface is affec...
