Acrylate adhesive and preparation method thereof

Abstract

The invention discloses a new acrylic ester adhesive agent, which comprises the following two components A and B in the weight proportion of A of 90-120 shears and of B of 2-40 shears, wherein, the said component A is made of the following raw materials in weight proportion of methyl methacrylate of 80-120 shears, acrylonitrile-butadiene-styrene of 20-35 shears and modified arylamine of 1-4 shears, the said component B is made of the following raw materials in weight proportion of benzoyl peroxide of 5-15 shears, methacrylic acid of 5-15 shears and talcum powder of 10-30 shears. The acrylic ester adhesive agent in the invention cures mildly and stably in room temperature and disappears the phenomenons vigorous heat release or imploding detonation when the curing time in room temperature is controlled in 10-90 min and the one-time dosage is lass than 10 g. The shelf life of the said acrylic ester adhesive agent in room temperature can reach more than half a year.

Description

technical field

[0001] The invention relates to an adhesive, in particular to an acrylate adhesive and a preparation method thereof, belonging to the field of chemical industry. Background technique

[0002] Most of the commonly used and popular second-generation acrylate adhesives (SGA) of type A and B on the market are fast-curing at room temperature, and the curing time at room temperature is mostly in the range of 1 minute to 15 minutes. Rapid curing brings a lot of convenience to use, but if the amount of application exceeds 10g at one time, it is prone to violent exotherm or explosion during curing, which makes it impossible for this glue to be formulated and used in large quantities at one time or even used for potting and pouring. In addition, the room temperature fast curing adhesive still has the following defects that need to be solved urgently: the storage period at room temperature is short; during storage, the components containing peroxides are unstable and ea...
