Composite adhesive

Abstract

The invention discloses a composite adhesive. The adhesive comprises, by weight, 20-30 parts of magnesium oxide, 5-10 parts of sodium sulfate, 20-30 parts of rosin, 30-40 parts of vinyl acetate, 10-20 parts of polyvinyl alcohol and 30-50 parts of ethanol. The composite adhesive has the advantages of being simple in producing method, low in cost, convenient to operate during usage, non-toxic, harmless, high in adhesion, good in permeability and environment-friendly; and raw materials of the adhesive are easy to obtain.

Description

technical field [0001] The invention relates to an adhesive, in particular to a composite adhesive. Background technique [0002] There are many types of adhesives on the market, but most of them contain harmful substances, which are easy to volatilize, which is not only not conducive to environmental protection, but also harmful to the health of operators. In addition, the single-performance adhesive not only has poor performance, but also has complicated manufacturing process, high production cost, weak cohesive force and poor leakage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite adhesive with strong cohesive force, good leakage, simple manufacturing process and low production cost. [0004] In order to solve the problems of the technologies described above, the technical scheme adopted in the present invention is as follows: [0005] A composite adhesive comprising the following components...
