A kind of material for vulcanization mold surface treatment and its preparation method and application

Abstract

The invention discloses a material for surface treatment of vulcanization molds, its preparation method and application. The material is composed of thermosetting acrylic resin, silane coupling agent, silanol oligomer, carbodiimide, inorganic oxide , deionized water and silicone polyoxyethylene ether are composed according to a specific ratio. Experiments have proved that the material of the present invention can be coated on the surface of metal molds at room temperature without special equipment, simple and quick to operate, easy to construct and independently complete the coating operation, and the bonding force between the coating film and the surface of the metal mold is strong, and has a low surface area. Excellent performance of hydrophobic and oleophobic, which can reduce or eliminate the use of release agent, and also has a good anti-rust effect, which significantly prolongs the mold washing cycle and mold service life, and significantly reduces the number of mold washing and enterprise costs. ; Moreover, the material is a water-based product, does not contain solvents, and is safe for transportation, storage, and construction; it is especially valuable for tire manufacturers to achieve energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a material for vulcanization mold surface treatment, a preparation method and application thereof, and belongs to the technical field of mold surface treatment. Background technique [0002] The so-called vulcanization mold refers to the metal model used for vulcanization molding of rubber products (such as tires). During the high-temperature and high-pressure vulcanization process, low-molecular carbides, sulfur-containing, and zinc-containing compounds will gradually deposit on the surface of the mold, forming uneven scales, which will affect the appearance quality of the vulcanized product and easily cause "pattern roundness". Therefore, the surface treatment of vulcanized molds has always been an important link in the production enterprises of rubber vulcanized products. Especially in tire manufacturing enterprises, the cleaning of tire molds is particularly important and prominent. If it is not cleaned for a long time It ...

Problems solved by technology

This method has little effect and short service life. Usually, the release agent needs to be sprayed every 4 to 6 hours, which affects the production efficiency. It is easy to cause pollution. The appearance of the 1st to 3rd tires vulcanized after spraying the release agent has oil stains, which affects the appearance quality of the tires and produces "scrap failure rate"
