Abstract

The embodiment of the invention discloses a water-base sealant for automobiles. The water-base sealant comprises the following components in mass ratio: pure crylic acid copolymer emulsion, a water soluble resin, di-n-butyltin dilaurate, carboxymethylcellulose, polyvinyl chloride, talcum powder, heavy calcium carbonate, phenethyl alcohol and clay. The water-base sealant is prepared by taking the crylic acid copolymer emulsion as a base material together with a plasticizer, a thickening agent, assistants and the like, and has the characteristics of being non-poisonous, tasteless, non-combustible, nonexplosible, free of environment pollution, low in price and the like.

Description

technical field [0001] The invention relates to the field of sealants, in particular to a water-based sealant for automobiles and a manufacturing process thereof. Background technique [0002] Sealant has its particularity in terms of sealing in automobile maintenance. Because most of the joint surfaces are deformed and damaged to varying degrees after use and disassembly, making it more difficult to seal and prevent leaks, making the "three leaks" problem particularly prominent in the auto repair industry. Due to the location and high pressure of some parts, the incidence of oil leakage failures has always been high, which has become a major problem in improving quality. For example, the side cover of the valve chamber of the engine is located on the side, and the inside has the effect of gas pressure. In addition, the side cover is made of iron and is easily deformed, and its structure is fastened by middle bolts, etc., which makes the oil leakage problem at this part par...
