Impervious permanent bonding wood plastic and timber adhesive, and preparation method thereof

Abstract

The invention relates to a wood plastic and timber adhesive, and especially relates to an impervious permanent bonding wood plastic and timber adhesive, and a preparation method thereof. The impervious permanent bonding wood plastic and timber adhesive mainly comprises 21.1 to 24.3 parts of polyformaldehyde resin, 15.2 to 17.4 parts of polyacrylamide emulsifier, 7.2 to 9.5 parts of epoxy resin, 2.3 to 4.2 parts of white latex, 7.2 to 10.4 parts of a curing agent, 1.1 to 1.6 parts of cellulase, 0.6 to 1.2 parts of powdered steatile, 7.0 to 9.3 parts of modified tree ash, and 2.3 to 3.6 parts ofdimethicone. The impervious permanent bonding wood plastic and timber adhesive is high in bonding capacity, and is capable of realizing permanent bonding; when the impervious permanent bonding wood plastic and timber adhesive is used for wood products, no penetration or water contact deterioration is caused; when the impervious permanent bonding wood plastic and timber adhesive is used for bonding of timber with timber, or composite bonding of timber with wood plastic, bonding capacity is excellent, and no penetration is caused in using process, wood products can be protected from weather, and using quality is ensured.

Description

technical field [0001] The invention relates to an adhesive glue for wood-plastic products and wood, in particular to an adhesive glue for non-permeable and permanent bonding between wood-plastic products and wood and a preparation method thereof. Background technique [0002] In the commonly used wood board or wood-plastic board application, no matter what thickness the board is, it can be processed and shaped according to the thickness size. Resources are scarce and require high financial support, which not all consumers can afford. However, if wood-plastic materials are used to prepare wood-plastic products, because the wood-plastic material is relatively flexible, it is easy to deform the wood-plastic material when long-term force is applied Therefore, even if the thickness of the wood-plastic production design is thicker, it cannot be avoided. At the same time, the thickness of the wood-plastic board should not be designed too thick according to the needs of life. There...

[0002] In the commonly used wood board or wood-plastic board application, no matter what thickness the board is, it can be processed and shaped according to the thickness size. Resources are scarce and require high financial support, which not all consumers can afford. However, if wood-plastic materials are used to prepare wood-plastic products, because the wood-plastic material is relatively flexible, it is easy to deform the wood-plastic material when long-term force is applied Therefore, even if the thickness of the wood-plastic production design is thicker, it cannot be avoided. At the same time, the thickness of the wood-plastic board should not be designed too thick according to the needs of life. Therefore, in order to save costs and protect the environment, people use wood and wood-plastic composites. However, the bonding problem is another problem in the process of use. The bonding glue commonly used by the public can basically satisfy the ability to bond the two together, but after a long time Under normal use conditions, the glue is easily affected by the humid climate, and the glue will permeate or deteriorate and lose its bonding ability, resulting in a decrease in the quality of the composite board, or even the failure to continue to use it.
