Problems solved by technology

The strength and weather resistance of the polyvinyl acetate emulsion used for the initial splicing of wood cannot meet the use requirements and the industry LY / T1601 standard
The vinyl acetate copolymer emulsion / curing agent special splicing glue that appeared later has good bonding effect on soft woods such as pine and birch, but the bonding strength to hard woods such as oak and ash is not high, especially when it is wet. The strength cannot meet the requirements

Abstract

The invention belongs to an environment-friendly type laminating glue, and particularly relates to a high-strength double-component laminating glue and a preparation method of the high-strength double-component laminating glue. The high-strength double-component laminating glue comprises a host agent and a curing agent; the host agent comprises 40-60% of vinyl acetate emulsion, 2-4% of polyvinyl alcohol, 1-5% of functional monomer, 0-1.5% of plasticizer, 15-25% of inorganic filler, 0.05-0.2% of dispersing agent, 0.05-0.2% of de-foaming agent, 0.05-0.2% of fungicide, and 5-30% of de-ionized water; the curing agent is poly-methylene poly-phenyl poly-isocyanates; the preparation method is as follows: adding the vinyl acetate emulsion, the functional monomer, the dispersing agent and the de-foaming agent in a high-speed dispersing kettle in sequence, slowly adding the inorganic filler, stirring with high speed, thereby obtaining flowable pulp-shaped mixture, then adding polyvinyl alcohol aqueous solution, a plasticizer and fungicide, thereby obtaining the high-strength double-component laminating glue. The high-strength double-component laminating glue excludes organic solvent, so that the glue belongs to environment-friendly type glue product, the product spliced wood is high in strength and excellent in waterproofing property.

Description

technical field [0001] The invention belongs to an environment-friendly water-based adhesive, in particular to a high-strength two-component puzzle glue and a preparation method thereof. Background technique [0002] With the improvement of the quality of life, people's demand for solid wood furniture and solid wood decoration is increasing day by day, but due to the lack of forest resources, large-diameter profiles cannot meet people's needs. The glulam spliced ​​by small pieces of wood is of the same material as the large-diameter profile. On the one hand, it meets people's demand for solid wood, and on the other hand, it solves the problem of scarcity of large timber. Therefore, wood splicing has developed rapidly in recent years. [0003] In order for the spliced ​​glulam to achieve the performance of large-diameter profiles, it is required that the glue used in wood splicing has strength and weather resistance that exceed the wood itself. The polyvinyl acetate emulsion...
