Problems solved by technology

The Chinese invention patent with the patent number CN103184032B discloses a soybean gum and its manufacturing method, which improves the insect-proof performance by adding pyrethroid insect repellents to the soybean gum raw materials, but some pyrethroid insect repellents are used in soybean protein-based gums. It is easy to disperse unevenly in the adhesive system, which affects the cross-linked network formed by soybean protein glue on the surface of the veneer, and will greatly reduce the overall stability and water resistance of the adhesive over time

Abstract

The invention relates to an artificial veneer composite formaldehyde-free adhesive. The invention is characterized in that the formaldehyde-free adhesive is prepared from water, soybean protein, inorganic alkali, silicate, a surfactant, a polyamide polyamine epoxy chloropropane resin and a cyclodextrin-pyrethroid inclusion compound. The soybean protein accounts for 10-50 wt% of the formaldehyde-free adhesive; the inorganic alkali accounts for 3-5% of the soybean protein; the silicate accounts for 5-7% of the soybean protein; the surfactant accounts for 2-12% of the soybean protein; the polyamide polyamine epoxy chloropropane resin accounts for 0.2-15% of the soybean protein; and the cyclodextrin-pyrethroid inclusion compound accounts for 0.01-1.2 wt% of the formaldehyde-free adhesive. By improving the existing soybean-protein-base adhesive, the formaldehyde-free adhesive still has excellent binding strength, water resistance and vermin resistance on the premise of lowering the free formaldehyde.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to an formaldehyde-free adhesive and a preparation method thereof. Background technique [0002] In 2016, China's artificial veneer output was 883558m 3 , the demand for adhesives in my country has grown rapidly, and the average annual growth rate has been around 20% for more than 10 years. Among them, the three-aldehyde glue, namely urea-formaldehyde, phenolic and melamine-formaldehyde resin glue, is about 6 million tons, with the largest output, accounting for about 40% of the total adhesive production. . Although after years of hard work, the production level of wood-based veneer adhesives in my country has been greatly improved, and the environmental protection characteristics of wood-based veneer and its products have been greatly improved, but many enterprises produce wood-based panels and their products, such as furniture and wooden floors. , Indoor wood decorat...
