Problems solved by technology

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. , some stains are easy to remain after cleaning, and it is easy to cause adsorption stains

Abstract

The invention discloses a waterproof plastic mold coating and application thereof and belongs to the technical field of molds. The waterproof plastic mold coating disclosed by the invention comprisesthe following components in parts by weight: 50-60 parts of an acrylic emulsion, 20-30 parts of a phenolic resin, 20-30 parts of polytetrafluoroethylene, 10-20 parts of an epoxy resin, 5-10 parts of silica, 1-5 parts of a silane coupling agent, 1-3 parts of filming aids, 1-2 parts of a defoaming agent, 1-2 parts of a thickening agent and 50-60 parts of a solvent. When being applied to the surfaceof a plastic mold, the waterproof plastic mold coating disclosed by the invention not only is capable of effectively preventing water, but also has an anti-corrosion protection function on mold steel,and in addition meets temperature requirements on thermoplastics.

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 ...
