Abstract

The invention discloses a high-mildew-resistance and water-resistance soybean meal protein adhesive and a preparation method thereof, and particularly relates to the technical field of adhesives. Thehigh-mildew-resistance and water-resistant soybean meal protein adhesive is prepared from the following components in parts by mass: 10-50 parts of degreased soybean meal powder, 80-120 parts of water, 1-20 parts of a cross-linking agent, 0.2-6 part of a natural mildew inhibitor and 0.5-8 part of a viscosity regulator. The preparation method of the high-mildew-resistance and water-resistance soybean meal protein adhesive comprises the following steps: S102, uniformly mixing degreased soybean meal powder, water and a cross-linking agent to prepare viscous liquid; S104, adding a natural mildew preventive into the viscous liquid obtained in the S102, and carrying out dispersion treatment by using mechanical dispersion equipment until the temperature of the viscous liquid does not exceed 50 DEG C in the dispersion process; and S106, adding a viscosity regulator into the viscous liquid obtained in S104, and controlling the temperature not to exceed 70 DEG C in the stirring process to finally prepare the adhesive. According to the technical scheme, the problems that an existing soybean meal protein adhesive is prone to mildewing and poor in viscosity are solved, and the soybean meal protein adhesive can be used for improving the adhesion performance of artificial boards.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a highly mildew-proof and water-resistant soybean meal protein adhesive and a preparation method thereof. Background technique [0002] China's wood-based panel industry is huge, and its output accounts for more than 50% of the world's total wood-based panel production, and it is showing an upward trend year by year. Wood adhesives are an important part of the wood-based panel manufacturing industry. Traditional aldehyde-based resins have excellent bonding performance, but have the problem of formaldehyde release, which makes it difficult to match the current market demand and policy orientation. As a substitute for traditional aldehyde resin adhesives, soybean meal protein adhesives have good environmental protection properties and can be used in the manufacture of multi-layer boards, large-core boards, particle boards and other wood-based board products, especially in the ma...
