Abstract

The invention discloses an environment-friendly self-curing epoxy resin adhesive and a preparation method thereof. The adhesive is prepared from the following components in parts by weight: 30 to 50 parts of fluororubber, 10 to 20 parts of modified epoxide resin, 10 to 20 parts of perchloro-ethylene resin, 5 to 15 parts of polyvinyl alcohol, 4 to 12 parts of methylcellulose, 8 to 14 parts of percarbamide, 4 to 12 parts of potassium hydroxide, 5 to 10 parts of epoxy chloropropane, 4 to 12 parts of methacrylic acid, 8 to 20 parts of dianthus chinensis extracting solution and 4 to 10 parts of turpentine. The preparation method disclosed by the invention is simple; the preparation process is environment-friendly and pollution-free; the prepared adhesive has the advantages of oil resistance, good corrosion resistance, high adhesion as well as no toxicity and no irritating odor.

Description

technical field [0001] The invention relates to the technical field of adhesive preparation, in particular to an environment-friendly self-curing epoxy resin adhesive and a preparation method thereof. Background technique [0002] At present, the adhesives used in the wood-based panel manufacturing industry at home and abroad are mainly urea-formaldehyde resin, phenolic resin, melamine-formaldehyde resin, etc. This type of adhesive has a high content of free formaldehyde, and slowly releases toxic formaldehyde gas during use, causing harm to the human body. In order to reduce the emission of formaldehyde gas, the domestic research idea is to improve the original technical route of synthesizing urea-formaldehyde resin in an attempt to reduce the content of free formaldehyde. Such as adding formaldehyde capture agents such as urea and melamine; on the other hand, trying to use cheap biomass polyhydroxy compounds as raw materials to prepare wood adhesives to replace formaldehy...
