Tackiness agent for automobile tank

Abstract

The invention belongs to the field of resin adhesion, and in particular relates to a tackiness agent for an automobile tank. The tackiness agent is characterized by comprising components A and B, wherein the proportion of the components A and B is 1:1; the component A comprises the following compositions by weight percent: 2-5% of MAA (methyl acrylic acid), 35-45% of MMA (methyl methacrylate), 10-15% of hydroxyethyl methacrylate, 5-10% of ethylene glycol dimethacrylate, 15-22% of toughening resin, 0-30% of elastomer and 2-5% of initiator; and the component B comprises the following compositions by weight percent: 2-5% of MAA, 15-20% of hydroxyethyl methacrylate, 6-10% of organosilicon polymer, 35-45% of MMA, 15-22% of toughening resin, 0-30% of elastomer and 0.8-1.5% of accelerator. The tackiness agent provided by the invention has good mechanical property, storage stability, weather resistance, water tolerance and the like, can be quickly solidified at room temperature, has good fuel oil soaking resisting property, and is especially suitable for manufacturing of automobile tanks and products with similar applications.

Description

technical field [0001] The invention belongs to the field of adhesive resins, and in particular relates to an adhesive used for automobile oil tanks. Background technique [0002] In recent years, with the development of the economy, China's automobile industry has developed substantially. China's automobile production has risen from about 3 million in 2002 to about 13 million in 2009. In 2010, China's automobile sales ranked first in the world, reaching 1806 10,000 vehicles, and the increase in output also hit a record high. With the increasingly stringent international environmental protection laws and requirements for energy saving and emission reduction, as well as people's pursuit of low-carbon life, the California PGEV standard stipulates that from 2005, the fuel leakage of each car within 24 hours must be less than 54mg. This puts higher demands on the fuel tank of the automobile. [0003] The fuel tank is an important safety part of the car, it must be firm, sealed...

Problems solved by technology

However, at present, the SGA produced by major manufacturers has the same problem: the strength is not high enough, and the storage time is too short. These two shortcomings seriously hinder the expansion of its application range.
