Abstract

The invention discloses a waterproof plastic mold coating and its application, belonging to the technical field of molds. The waterproof plastic mold coating of the present invention comprises the following components in parts by weight of raw materials: 50-60 parts of acrylic emulsion, 20-30 parts of phenolic resin, 20-30 parts of polytetrafluoroethylene, 10-20 parts of epoxy resin, 5-10 parts of silicon dioxide, 1-5 parts of silane coupling agent, 1-3 parts of film-forming aid, 1-2 parts of defoamer, 1-2 parts of thickener, and 50-60 parts of solvent. The waterproof plastic mold coating of the invention is coated on the surface of the plastic mold, not only can effectively waterproof, but also can protect the mold steel against corrosion, and can meet the temperature requirement of thermoplastic.

Description

technical field [0001] The invention relates to a waterproof plastic mold coating and its application, belonging to the technical field of molds. Background technique [0002] With the application of plastic products in industry and daily life more and more widely, and the existing plastic products are becoming more and more refined, the demand for mold steel in the plastic mold industry is becoming more and more stringent. In plastic molding processing, whether the surface of the mold is smooth or not plays an important role in the quality of the product. After the plastic mold has been used for a period of time, some oil, dirt, pollutants, rust and scale will adhere to the surface. Therefore, it is necessary to clean the plastic mold. However, the surface of the existing plastic mold does not have waterproof function, and it is difficult to clean. , After cleaning, some stains are easy to remain, and it is easy to cause adsorption of stains. Contents of the invention ...
