Description
Technical field
The invention belongs to acrylic acid structure adhesive fields, and in particular to one kind can room temperature fast-curing, and using temperature
The degree high temperature resistant bi-component acrylic sqtructural adhesive that performance does not reduce after -40 DEG C -180 DEG C, high temperature.
Background technology
Presently commercially available two-component acrylate structural adhesive is mostly rubber toughened system, rapid curing or is passed through at room temperature
It is appropriate to heat to accelerate solidified and located, cross-linked structure is formed, is suitble to binding metal, engineering plastics and other base materials.Acrylic acid
Ester gum stick can provide the performance of high shear strength, peel strength, impact strength and chemical resistance, cohesible base material range
Extensively, required surface treatment is lacked.Since it is with good flexibility, for different substrate materials bonding when, being glued workpiece will not
Bond failure is caused due to linear expansion coefficient difference, this advantage is also that other structures adhesive is incomparable.
But it is more and more extensive with the application of adhesive, client is to the performance of adhesive it is also proposed that higher and higher will
It asks.The temperature tolerance of adhesive is exactly one of them.Such as in automobile manufacture industry, vehicle body need to pass through electrophoresis process, environment temperature
Up to 180 DEG C, used structure glue should be able to provide certain intensity in this period, and its performance should not after electrophoresis
Less than performance before electrophoresis.The temperature tolerance for improving acrylic acid structure glue is generally filled out using the high Tg monomers of addition, heatproof resin and heatproof
The modes such as material.Epoxy structural rubber has better temperature tolerance relative to acrylic acid structure glue, but epoxy structural rubber has construction
And the shortcomings of curing mode is relative complex, and toughness is inadequate after curing.The present invention is organic with epoxy resin by acrylic acid structure glue
It is combined together, improves the temperature tolerance and weatherability of system.
Invention content
Higher-strength is still kept during to solve the problems, such as that adhesive uses at high temperature, the present invention provides a kind of high temperature resistants
Bi-component acrylic sqtructural adhesive, have can room temperature fast-curing, temperature in use performance after -40 DEG C -180 DEG C, high temperature
It does not reduce, the advantages that good weatherability.
A kind of high temperature resistant bi-component acrylic sqtructural adhesive of the present invention, the adhesive include A, B component, the A groups
Point be by：1-5 parts of acrylic acid, 30-60 parts of acrylic ester monomers, 15-30 parts of toughener, 1-3 parts of reducing agents, 0.3-3 parts of rings
Oxygen curing catalysts form；B component is by 30-50 parts of epoxy resin, 4-10 parts of oxidant compositions.
A kind of high temperature resistant bi-component acrylic sqtructural adhesive temperature in use of the present invention is after -40 DEG C -180 DEG C, high temperature
Performance does not reduce, and has good cementability, flexibility and weatherability.
Above-mentioned acrylic acid is at least one of acrylic acid and methacrylic acid.
Above-mentioned acrylic ester monomer for methyl methacrylate, Isobutyl methacrylate, isodecyl methacrylate,

Resin etc..
This technology is mainly characterized by formula containing 0.3-3 parts of curable epoxide catalyst, the curable epoxide catalyst
Ability with catalysis epoxy and carboxylic acid or anhydride reaction at room temperature, due to containing 1-5 parts of (methyl) acrylic acid in formula, provides
Carboxylic acid functional can be crosslinked with the epoxy resin cure of addition.
The present invention combines epoxy resin and acrylic acid structure glue, passes through the work of curable epoxide catalyst
With when acrylic system cures, epoxy resin and (methyl) acrylic acid crosslinking curing improve the intensity of adhesive at room temperature
And heat-resisting quantity, and improve the weatherability of product.
Specific embodiment
The principles and features of the present invention are described below, and the given examples are served only to explain the present invention, is not intended to limit
Determine the scope of the present invention.
Embodiment 1：
