AI Technical Summary

Problems solved by technology

During the high temperature time in summer, the pot life is too short, so it is difficult to construct and cannot be applied. The development of a styrene-acrylic emulsion for panel adhesive with a long pot life can well meet the needs of market development and has a good development prospect.

Abstract

The invention discloses a styrene-acrylic emulsion board splicing adhesive with a long activation period, the board splicing adhesive is composed of a main agent and a curing agent according to a mass ratio of 100: 15, the main agent is composed of a styrene-acrylic emulsion, Chuanwei polyvinyl alcohol 088-50 and calcium carbonate; the styrene-acrylic emulsion is prepared from butyl acrylate, styrene, vinyl versatate, methyl methacrylate, acrylic acid, a hydroxyl monomer, a functional monomer, an A171 silane coupling agent, an initiator, an emulsifier, deionized water, baking soda, an oxidizing agent, a reducing agent and a defoaming agent. The board splicing adhesive has the characteristic of long activation period and conforms to the national ten-ring environmental protection standard, and the dry and wet strength of the plate splicing adhesive passes the Japan agriculture and forestry specification JIS K6806-2003 standard test.

Description

technical field [0001] The invention belongs to the technical field of emulsion polymerization, and in particular relates to a long-activation-period styrene-acrylic emulsion puzzle glue and a preparation method thereof. Background technique [0002] The two-component panel glue is mainly the ratio of the main agent and the curing agent. This two-component panel glue can be easily used in various climates and has good heat resistance. Common cork, hardwood, extra hardwood and other tree species in our life can be bonded with jigsaw glue. It refers to the adhesive used to assemble wood products such as glulam, which is a fast bonding type. It is widely used in splicing production of structural or non-structural glulam in the fields of wood-based panels, jigsaw panels and composite floors. The main agent of two-component puzzle glue is generally a specially prepared and compounded emulsion, and the curing agent is generally isocyanate. Two-component puzzle glue is a water-b...
