AI Technical Summary

Problems solved by technology

Among them, the paraffin wax waterproof edge sealing technology has high freezing point, low hardness and cannot form a continuous and dense sealing layer. Therefore, in practical applications, it needs hot melting and heat preservation, is easy to solidify and block, has poor wear resistance, and poor hot water resistance. It cannot prevent the release of free formaldehyde inside the laminate floor and other defects; the organic solvent-based waterproof edge banding technology has problems such as flammability and explosion, secondary pollution of organic solvents, and high cost of use; the thermo-curable waterproof edge banding technology has high operating costs. High, slow processing speed; and the existing water-soluble waterproofing agent can not adapt to the rapid assembly line production of composite laminated floor waterproofing due to the long drying and film-forming time, and cannot be applied in the actual production process

Abstract

The present invention discloses one kind of waterproof edge sealing agent for floor board, especially for composite reinforced floor board. The waterproof edge sealing agent has the features of safety, environment friendship, quick drying, easy use, etc. It can form one smooth, transparent, compact and tough watertight layer in the periphery of composite reinforced floor board to obstruct inward water permeation and outward free formaldehyde release and to make composite reinforced floor board durable and environment friendly.

Description

technical field [0001] The present invention relates to a kind of waterproof edge sealing agent for the wood fiber surface of the groove and tenon of the floor, especially the composite reinforced floor, more specifically, the present invention relates to a kind of water-based polymer waterproof which does not need heat curing and does not contain organic solvent Edge sealant. Background technique [0002] Composite laminate flooring is popular among consumers due to its advantages of high wear resistance, high hardness, heat resistance, natural wood texture, good decorative effect, surface not easy to be polluted, simple installation and maintenance, and high cost performance. However, its poor waterproof performance, high water absorption rate and formaldehyde release have always been insurmountable weaknesses, especially when the floor substrate has poor water resistance and the installation and sealing around the groove and tenon are not tight, external moisture can easi...
