Abstract

The invention discloses an improved wood adhesive. The improved wood adhesive is prepared by using the following raw materials, by weight, 2.5-4.2 parts of bisphenol epoxy resin, 2-4 parts of hydroxyl terminated polybutadiene, 1.5-2.7 parts of isomeric alcohol ethoxylates, 2.5-3.7 parts of sec-octylphenol polyoxyethylene ether, 1.2-2.3 parts of dibutyltin dilaurate, 0.5-0.8 parts of diglycerol, 1.2-1.8 parts of alkenyl succinic acid and 2.5-3.6 parts of ethyl chrysanthemumate. Compared with present products, the improved wood adhesive has the advantages of reduction of free formaldehyde reaching E0 grade to below 0.11, environmental protection, and long storage time, and a bamboo wood product using the improved wood adhesive has very good water and moisture resistance; raw materials of the improved wood adhesive can be easily obtained, so the improved wood adhesive is suitable for batch production; and the addition of the odor absorber rosin resin makes the strength and the pre-pressing effect of a resin adhesive increased and the free formaldehyde reduced.

Description

technical field [0001] The invention relates to an improved solid wood adhesive and belongs to the field of building materials. Background technique [0002] Adhesives for bamboo and wood products are used to bond wood and wood or the surface of wood and other objects together by gluing. This kind of adhesive is necessary in bamboo products and wood products processing industries, such as plywood, The adhesive is required for the production of MDF, laminates, decorative cladding and blockboard, etc. The emergence of adhesives not only plays an important role in saving bamboo and wood products and simplifying the production process, but also can glue materials with different properties such as metal or plastic with materials such as bamboo and wood to make composite materials with various properties, so as to play the role of bamboo and wood. The unique function of the product provides some special purposes. Humans have a long history of using adhesives for bamboo and wood ...
