Problems solved by technology

The main components of jigsaw glue are latex with strong adhesive ability and auxiliary raw materials. In recent years, with the improvement of people's jigsaw glue product technology and quality requirements and the enhancement of environmental protection awareness, people are more concerned about the safety and security of the jigsaw glue production process. Low cost, ease of operation, and higher requirements are put forward for the bonding strength, service life and environmental protection of panel glue products. In the prior art, the production process of panel glue often contains oily raw materials. There are potential safety hazards and high cost of raw materials. The production process of some panel adhesives with styrene-acrylic emulsion as the main agent is complicated, and the anti-aging ability is poor, and the bonding strength is low. At the same time, the existing panel adhesives mostly contain Volatile substances such as formaldehyde cannot meet the needs of indoor use

Abstract

The invention discloses a wood splicing adhesive and belongs to the field of adhesives. The wood splicing adhesive comprises the components in percentage by mass: 20-30% of styrene-acrylate emulsion,20-30% of ground calcium carbonate, 13-20% of polyvinyl alcohol emulsion, 9-15% of vinyl acetate-acrylate emulsion, 9-15% of vinyl acetate-ethylene copolymer emulsion, 5-9% of water, 0.6-1.0% of plasticizer and 0.05-0.1% of defoaming agent. The production process of the wood splicing adhesive disclosed by the scheme is safe, easy to implement and low in cost; and the wood splicing adhesive productis high in bonding strength and ageing resistance as well as better in environment protection property.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a puzzle glue. Background technique [0002] Panel glue refers to the adhesive used for splicing glulam and other wood products, and is suitable for panel bonding of non-structural materials and glulam for structural materials. The main components of jigsaw glue are latex with strong adhesive ability and auxiliary raw materials. In recent years, with the improvement of people's jigsaw glue product technology and quality requirements and the enhancement of environmental protection awareness, people are more concerned about the safety and security of the jigsaw glue production process. Low cost, ease of operation, and higher requirements are put forward for the bonding strength, service life and environmental protection of panel glue products. In the prior art, the production process of panel glue often contains oily raw materials. There are potential safety hazards and high cost of raw m...
