Problems solved by technology

[0002] Most of the existing composite wooden doors are made by bonding miscellaneous wood particles with a large amount of adhesive. This kind of wooden door uses a large amount of glue and releases high concentration of formaldehyde in the later stage, which is not conducive to the health of users.
Moreover, the composite wooden doors on the market are prone to swell and crack under high temperature in summer, mainly due to thermal expansion and contraction of the adhesive contained.

Abstract

The invention relates to an anti-thermal expansion adhesive used for a wood door. The adhesive is mainly composed of, by mass, 30 to 40 parts of starch adhesive, 3 to 6 parts of bismaleimide, 8 to 12parts of a PU adhesive, 2 to 4 parts of an inorganic heat conductive agent, 2 to 4 parts of an antifoaming agent, 3 to 5 parts of an antioxidant, 10 to 15 parts of a diallyl compound, and 3 to 5 partsof a nonionic surfactant. The adhesive has the advantages of low formaldehyde release, good adhesion performance and low production cost.

Description

technical field [0001] The invention relates to the technical field of auxiliary materials for furniture manufacturing, in particular to an anti-thermal expansion adhesive for wooden doors. Background technique [0002] Most of the existing composite wooden doors are made by bonding miscellaneous wood particles with a large amount of adhesive. This kind of wooden door uses a large amount of glue and releases high concentration of formaldehyde in the later stage, which is not conducive to the health of users. Moreover, the composite wooden doors on the market are prone to swell and crack under high temperature in summer, mainly due to the thermal expansion and contraction of the adhesive contained. Contents of the invention [0003] In order to solve the above technical problems and provide an adhesive for wooden doors that is not prone to high-temperature deformation and is relatively environmentally friendly, the present invention provides the following technical solution...
