Abstract

The invention discloses an emulsion-type antifoaming agent used for rubber and plastic, which belongs to the chemical preparation field. The emulsion-type antifoaming agent used for rubber and plastic comprises the following components by weight part: 13-20 parts of alkylol amine, 40-50 parts of alkymer, 25-30 parts of aliphatic acid, 5-10 parts of assisted antifoaming agent, 4-10 parts of dispersant and a proper amount of water. The emulsion-type antifoaming agent is capable of eliminating foams, and has the advantages of simple preparation, easy operation, fast defoaming speed and strong foam inhibition capability, the emulsion-type antifoaming agent has no adverse influence on rubber and plastic polymers, no by-product, waste water, exhaust gas and solid waste materials can be generated during a reaction process, and no pollution is generated on environment.

Description

technical field [0001] The invention belongs to a defoamer, in particular to an emulsion type defoamer for rubber and plastic. Background technique [0002] Rubber and plastic is the collective name of the rubber and plastic industries. They are all subsidiary products of petroleum. They are all the same in source. However, in the process of making products, their physical properties are different, and their uses are even more different. The most common is tires. Plastics are becoming more and more widely used with the needs and uses of technology and markets, and they are inseparable from daily life. [0003] Both plastic and rubber belong to polymer materials, mainly composed of carbon and hydrogen atoms, and some contain a small amount of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms, which have special properties and uses. At room temperature, Plastic is solid, very hard, and cannot be stretched and deformed. Rubber is not very hard, but elastic,...
