Abstract

The invention relates to the technical field of adhesive film paper production, in particular to an amine-formaldehyde resin glue for silicon wafers, comprising the following components in parts by weight: 86-92 parts of amine-formaldehyde resin, 8-14 parts of nano-silicon, and 0.7-0.9 parts of curing agent , 0.1-0.3 parts of release agent, 0.1-0.3 parts of penetrating agent, 0.1-0.3 parts of dust remover, and 0.1-0.3 parts of anti-sticking agent. The present invention also provides a deodorizing film paper prepared by using the above-mentioned amine-formaldehyde resin glue for silicon wafers. In the present invention, silicon chips are added to the amine-formaldehyde resin, which has the function of purifying odor. The adhesive film paper of the invention can absorb bacteria, viruses in the air and peculiar smell emitted from the base material, so as to purify the air.

Description

technical field [0001] The invention relates to the technical field of film paper production, in particular to a silicon chip amine-aldehyde resin glue and a film paper that can deodorize prepared by applying the same. Background technique [0002] At present, the complaints about the odor of the overall wardrobe in the market rank among the top three of all complaints about the wardrobe. The odor is mainly related to the base material, and the current production technology of the base material cannot solve this problem, so it can only be solved by other means. improve. [0003] During furniture production, impregnated film paper will be glued on the surface of the base material, which can play the role of waterproof, moisture-proof and decoration. Amine-aldehyde resin is widely used in impregnated decorative film paper. The performance of amine-formaldehyde resin has great influence on the film The properties of the paper play a huge role. Contents of the invention [0...
