Abstract

The invention discloses an emulsion type wood starch adhesive and a preparation method thereof, which belongs to the technical field of adhesive preparation. With high-concentration starch milk as a main raw material, an emulsion type wood starch adhesive with a high solid content is prepared by a binary seed method. Compared with wood starch adhesives prepared by a traditional process, the product prepared by the preparation method is high in solid content, high in drying speed, good in film-forming property and high in bonding strength, and the comprehensive performance of the product reaches or exceeds the level of the currently commercially available high-quality white latex, so that the product can be widely applied to wood decoration and adhesion of artificial boards and plywood.

Description

technical field

[0001] The invention relates to an emulsion-type starch adhesive for wood and a preparation method thereof, belonging to the technical field of adhesive preparation. Background technique

[0002] Starch is an organic compound with abundant content in nature. It has the advantages of wide source, low price, renewable, completely degradable and non-polluting. A kind of adhesive for wood with low production cost, environmental protection and pollution-free can be prepared after acid hydrolysis, oxidation and graft copolymerization of starch. The solid content, bonding strength and drying speed of starch glue prepared by some current processes still need to be improved in order to be more widely used. The present invention aims at problems such as high viscosity of the system, uneven grafting reaction and poor storage stability caused by increasing the amount of starch and total solid content when the existing technology is applied to the preparation of high-sol...
