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.

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-based woodware coating, in particular to a two-component polyurethane termite-proof and insect-proof putty. Background technique [0002] At present, the anti-termite and insect-proof treatment of wood is mainly based on the soaking method and the brushing method, that is, the wood is soaked in a solution containing a drug, or the solution containing a drug is painted on the surface of the wood. Such as Chinese patent) low temperature and normal 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 have no ability to prevent termites and insects, but its disadvantages are that the drug is easy to run off and the duration of the drug effect is short; the drug is harmful to the human body and pollutes the environment; after the wood surface is painted with the drug solution, the paint eff...
