Soybean adhesive for water-resistant shaving board and preparation method thereof

Abstract

The invention discloses a soybean adhesive for a water-resistant shaving board and a preparation method thereof, and relates to an adhesive and a preparation method thereof, in particular to a modified soybean adhesive for production of boiling water boiling-resistant shaving boards, which aims at solving the technical problems of difficulty in adhesive applying in the production process of the shaving board due to large viscosity and difficulty in adapting to the production of the shaving board due to long hot pressing time in the existing soybean adhesive. The method comprises the following steps of 1, synthesizing of modified polyamide polyamine resin; 2, preparing of the adhesive. The prepared soybean adhesive for the water-resistant shaving board is prepared by adding 0.3 to 1.5% of curing agent and 10 to 25 parts of soybean meal into 100 parts of modified polyamide polyamine resin and mixing at room temperature. The soybean adhesive has the advantages that the viscosity is low, the adhesive is conveniently and uniformly sprayed onto the shaving board, the curing speed is high, the water-resistant property is good, and the soybean adhesive is especially suitable for preparing the boiling water boiling-resistant shaving board in the existing shaved board production line. The soybean adhesive belongs to the field of preparation of adhesives.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to a modified soybean adhesive used in the production of boiling-resistant particle boards. Background technique [0002] Particleboard is a wood-based panel made of wood, straw and other lignocellulose-based scraps, which are hot-pressed with adhesives; it is one of the three major wood-based panel products in my country, and its output is second only to plywood and fiberboard. At present, most of the adhesives used in the production of particleboard in my country are still formaldehyde-based synthetic resins (urea-formaldehyde resin adhesives and melamine-modified urea-formaldehyde resins). Formaldehyde will be released during use, and particleboard is mainly used in furniture manufacturing and interior decoration products in my country. Therefore, the problem of formaldehyde release from wood-based panels and the safety of the living environment are getting more and ...
