Abstract

The invention discloses an anti-sticking agent for melamine impregnated paper and a preparation method thereof. The anti-sticking agent for the melamine impregnated paper is prepared from the following components in parts by mass: 5 to 10 parts of diethylene glycol, 3 to 5 parts of a sodium hydroxide saturated solution, 8 to 12 parts of octanol polyoxyethylene ether, 6 to 10 parts of polyether, 10 to 15 parts of alkylphenol polyoxyethylene ether, 10 to 15 parts of isooctanol phosphate, 3 to 5 parts of alcohol ester, 0.3 to 0.5 part of a defoaming agent and 40 to 60 parts of water. By using anti-sticking agent disclosed by the invention in the melamine impregnated paper, not only can the melamine impregnated paper be difficult to stick and the storage period of the melamine impregnated paper be prolonged, but also the fluidity of paper glue on the melamine impregnated paper is increased, and the phenomena of bright stars and sand holes appearing during a pressing and sticking process are improved.

Description

technical field [0001] The invention relates to a release agent for melamine-impregnated paper and a preparation method thereof. Background technique [0002] At present, the melamine-impregnated papers of the prior art tend to stick together, especially in summer, which shortens its storage period. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a kind of anti-adhesive agent for melamine-impregnated paper, which can not only make the melamine-impregnated paper not easy to stick, but also prolong its storage period , and increase the fluidity of the paper glue on the melamine-impregnated paper, and improve the phenomenon of bright stars and blisters during the pressing process. [0004] In order to solve the problems of the technologies described above, the technical solution of the present invention is: a kind of release agent for melamine-impregnated paper, the compon...
