Abstract

The invention discloses an adhesive for a solid wood floor and a preparation method of the adhesive. The adhesive is a one-component moisturecuring polyurethane elastic adhesive which consists of polyether polyol, polyisocyanates, a plasticizer, padding, a catalyst, a water removing agent, a coupler and an antioxygen. The adhesive used to pave the solid floor overcomes the deficiencies that at present, in solid wood floor pavement, the solid wood floor is large in noise, free from elasticity, poor in stability, has sound like an empty drum, and cannot be used in a ground heating system and the like due to rough grounds which have to be used. The adhesive has the advantages of one-component moisturecuring, convenience in operation, strong adhesive strength, safety, environment friendliness and the like, and can be adjusted in different colors according to colors of the solid wood floors. The solid wood floors paved have the advantages of elasticity, comfort, low noise, and can be used in the ground heating system and the like, and the risk of deformation and crack of the solid wood floor can be reduced. The adhesive is suitable for paving various solid wood floors and elastically adhering skirting lines, thresholds and stairs and the like, and meanwhile the adhesive is further used for paving ceramic tiles.

Description

technical field [0001] The invention relates to an adhesive for flooring, in particular to an adhesive for solid wood flooring and a preparation method thereof. Background technique [0002] Solid wood flooring is a ground decoration material formed by drying and processing natural wood. The natural log texture and color patterns it presents give people a natural, soft, and friendly texture. At the same time, because of its warm winter and summer cool and good touch, it is an ideal material for floor decoration such as bedrooms, living rooms, and study rooms. Solid wood flooring has the advantages of good sound insulation, strong ability to adjust humidity, warm in winter and cool in summer, green and harmless, good decorative effect and durable. But there are also disadvantages such as difficult maintenance, poor stability, inability to be used in ground heating systems and high prices. And at present there is no one that can be used for solid wood floor to solve the prob...
