Novel solid wood adhesive

Abstract

The invention discloses a novel solid wood adhesive. The novel solid wood adhesive is prepared from the following raw materials in parts by weight: 2.5-4.2 parts of bisphenol epoxy resin, 2-4 parts of polybutadiene diol, 1.5-2.7 parts of saccharose oleate, 2.5-3.7 parts of sec-octyl phenol polyoxyethylene ether, 1.2-2.3 parts of laurinol dibutyl tin, 0.5-0.8 part of dipolyglycerol, 1.2-1.8 parts of butylated hydroxyl anisole and 2.5-3.6 parts of ethyl chrysanthemate. Compared with the prior art, the novel solid wood adhesive disclosed by the invention can be used for lowering free formaldehyde which is smaller than 0.11, so that the E0 level is achieved, and thus, the novel solid wood adhesive is relatively environmentally friendly. The novel solid wood adhesive disclosed by the invention is long in storage time, easily available for raw materials and more suitable for large-scale production, and a bamboo wood product adopting the novel solid wood adhesive has good water resistance and moisture resistance. By adding a smell remover rosin resin, the strength and pre-pressing effects of the resin adhesive are increased, and the free formaldehyde is lowered.

Description

technical field [0001] The invention relates to a novel solid wood adhesive, which 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 p...

Problems solved by technology

Bamboo and wood product adhesives used in the market today basically use urea-formaldehyde resin, which causes the main problem of high formaldehyde emission in the product
