It is vital, if the proportion of coupling agent is excessively high, the viscosity that will lead to acrylic copolymer and glass plate is too strong；If coupling agent
Proportion it is too low, it is unobvious to the reinforcing effect of acrylic copolymer to will lead to coupling agent；Only when coupling agent is 0.1~1.0
When part, coupling agent could carry out good reinforcing effect to acrylic copolymer, can effectively increase the low viscose glue stick of acrylic
Wear-resisting weather-proof high temperature resistance, corrosion resistance and the tensile strength of layer, so that the low viscose glue adhesive layer of acrylic is in hot environment
The service life is longer, and viscosity is moderate.
In order to adjust above embodiment acrylic copolymer viscosity, curing agent is added in acrylic copolymer.
One embodiment, the curing agent are isocyanates and epoxy hardener wherein at least one.Further, the curable epoxide
Agent includes: 1. alkaline curing agent, such as aliphatic diamine, polyamines, aromatic polyamine, dicyandiamide, imidazoles, modified amine etc.；
2. acid curing agent, such as organic acid anhydride, boron trifluoride and complex compound etc.；3. add-on type curing agent, such as fatty amines, fragrance
Race, cycloaliphatic ring class, modified amine, anhydride, Versamid and latency amine；And 4. catalytic curing agent, such as three
Grade amine and imidazoles.For example, the curing agent is made of isocyanates and epoxy hardener.For example, the curing agent is by 0.1
~3.0 parts of isocyanates and 0.1~0.5 part of epoxy hardener composition.In order to make acrylic copolymer hot environment keep compared with
Good thermal stability, reaches better heat resistance, the curing agent is preferably the better aromatic polyamine of heat resistance.Example
Such as, the curing agent is made of 0.1~3.0 part of isocyanates and 0.1~0.5 part of aromatic polyamine.For example, the curing agent by
0.1~3.0 part of isocyanates and 0.1~0.5 part of diaminodiphenyl-methane composition.It is appreciated that the curing agent be used for
Acrylic copolymer chemically reacts, and forms netted space polymers, that is, acrylic copolymer is promoted to be cured reaction, energy
The viscosity for enough reducing acrylic copolymer, so that the viscosity of acrylic copolymer and glass reaches certain desired value.
It should be noted that the proportion of acrylic copolymer and curing agent be also it is vital, if the proportion of curing agent
Excessively high, too strong with the curing reaction of acrylic copolymer, the mobility that will lead to acrylic copolymer is excessively weak, with glass plate
Viscosity is too low, can not adhering glass plate；It is excessively weak with the curing reaction of acrylic copolymer if the proportion of curing agent is too low, meeting
Cause the mobility of acrylic copolymer too strong, thermal stability is poor, and it is excessively high with the viscosity of glass plate, it is difficult under high temperature environment
Glass plate processing procedure is removed from glass plate with protective film and easily leaves residue glue；Only when curing agent is 0.2~3.5 part,
It is moderate with the curing reaction of acrylic copolymer, cause the better heat stability of acrylic copolymer, mobility is moderate, and can
The viscosity of acrylic copolymer and glass plate is reduced to desired value, so that the low viscose glue adhesive layer of acrylic is under high temperature environment
Still can be with strong bond macromolecule resistant substrates and glass plate, and it under high temperature environment can be relatively easily by glass plate system
Journey is removed from glass plate with protective film and will not leave behind residue glue to influence the planarization of glass plate.
Since acrylic copolymer and macromolecule resistant substrates are organic compounds, and glass is inorganic compound, therefore
Acrylic copolymer and the adhesion strength of macromolecule resistant substrates are higher than the adhesion strength of acrylic copolymer and glass.Through excessive
Secondary test discovery, when (adhesion strength a) is higher, and acrylic is low for the adhesion strengths of the low viscose glue adhesive layer of acrylic and macromolecule resistant substrates
(adhesion strength b) is lower and reaches certain numerical value and adhesion strength a is higher than adhesion strength b for the adhesion strength of viscose glue adhesive layer and glass plate
When to certain numerical value, glass plate processing procedure protective film can be easier to be stripped from glass plate and will not leave behind residue glue.It presses
