Abstract

The invention discloses an improved environment-friendly woodware adhesive. The adhesive is prepared from the following raw materials in parts by weight: 1.2-3.5 parts of rosin, 2.3-4.6 parts of blood meal, 2.3-4.5 parts of polyol polyoxyethylene ether carboxylic ester, 5-10 parts of tapioca adhesive, 2-6 parts of soybean protein concentrate, 0.8-1.6 parts of ammonium thiosulfate and 1.2-4 parts of sodium sulfosuccinate. The improved environment-friendly woodware adhesive has the beneficial effects that compared with existing adhesives, the adhesive can be implemented on conventional adhesive production equipment, without extra processing equipment; a method has the advantages of simple preparation process, mild reaction conditions and high process stability; as cheap and renewable starch is adopted as the main raw material, the adhesive does not release toxic and harmful gases and has good environmental harmonization; relative to common white latex, the adhesive has lower content of total volatile organic compounds and better environment-friendliness.

Description

technical field [0001] The invention relates to an improved environmental-friendly wood glue, which belongs to the field of building materials. Background technique [0002] As a kind of natural adhesive, starch adhesive has the advantages of light weight, no corrosion, no pollution, easy to obtain raw materials, low price, and convenient use. It is widely used for bonding paper, cotton fabrics, trademarks, etc. However, starch adhesives have disadvantages such as low bonding strength and easy mildew when exposed to moisture, which limits the application in the bonding of wood products. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the present invention is to provide an improved environmental-friendly wood glue, which has high bonding strength, is not prone to mildew when exposed to moisture, is relatively low in cost, and is environmentally friendly. [0004] In order to solve the above-men...
