Problems solved by technology

With the development of laminate flooring, lock-type splicing and glue-free installation methods are widely used, and the moisture-proof problem of exposed laminate floor substrates has attracted attention. Although some measures such as waxing, oiling, and painting have been adopted However, in these measures, the connection between the waterproof material and the base material is still mainly based on physical connection, and the moisture-proof and waterproof effect and durability are not ideal.

Embodiment Construction

[0019] The main process steps of the present invention are as follows: (1) select wooden material as raw material; (2) be processed into the finished product of required shape; (3) apply sealing agent on the specific surface of finished product; (4) described The blocking agent is prepared from diphenylmethane diisocyanate (MDI, 4,4'-diphenylmethane diisocyanate) and solvent.

[0020] The formula of the above sealing agent is: MDI (30%-80%)+solvent (70%-20%). During specific production, oil-soluble dyes or pigments can be added to the above-mentioned sealant to realize coloring while coating.

[0021] The above-mentioned solvents are volatile organic solvents with low toxicity, insoluble in water, good permeability and diffusivity, and no reaction with MDI, such as butanone and the like.

[0022] In practical applications, the above-mentioned finished product may be a reinforced floor, and the exposed substrate surface at the splicing groove of the reinforced floor is coated ...

Abstract

The present invention relates to a damp-proof and water-proof processing method for deep-processed finished products of wooden material. Its main process includes the following steps: 1. selecting and using wooden material as raw material; 2. making it into finished product with required form; 3. applying sealing agent on the speicific surface of finished product; and 4. the described sealing agent is prepared by using methylene diphenyl diisocyanate and solvent.

Description

Technical field [0001] The invention relates to the technical field of building decoration materials, which is a moisture-proof and water-proof processing method mainly used for deep-processed wood material products of laminate flooring. Background technique [0002] The floor is a commonly used decorative material in house decoration. The impregnated paper laminated wood floor is commonly known as laminate flooring, diamond board, etc. It has a wide range of markets and user groups, and its growth momentum remains unabated. [0003] The surface layer of laminate flooring is durable and has excellent waterproof and moisture-proof performance, but the base material at the splicing and groove of laminate flooring is exposed, which becomes a weak point for moisture-proof and release of free aldehyde. In the floor installation, white latex glue is usually used to splice the tongue and groove, but it does not fundamentally solve the moisture-proof problem of laminate flooring. W...
