Abstract
A kind of flame-proof acrylic pressure sensitive adhesive and preparation method thereof includes: Isooctyl acrylate monomer, vinylacetate, hydroxy-ethyl acrylate, glycidyl acrylate, azodiisobutyronitrile and ethyl acetate, the fire retardant of acrylate polymer is halogen-free flame retardants, and the mass fraction of halogen-free flame retardants is 5~10 parts；The mass fraction of its each component are as follows: 50~80 parts of Isooctyl acrylate monomer, 10~30 parts of vinylacetate, 1~10 part of hydroxy-ethyl acrylate, 0.2~2 part of glycidyl acrylate, 0.2 part of azodiisobutyronitrile and 150 parts of ethyl acetate.For the present invention compared with traditional technology, adding different amounts of fire retardant influences very little to peeling force.To reach flame retardant effect, a large amount of fire retardants are added, although having an impact to peeling force, can still keep higher peeling force.
Description
Technical field
The present invention relates to chemical fields, and in particular to a kind of flame-proof acrylic pressure sensitive adhesive and preparation method thereof.
Background technique
Pressure sensitive adhesive is applied to the every field of daily life, and different field has different requirements to pressure sensitive adhesive.In electrician
Electronics, the pressure sensitive adhesive tape of packages printing route, label etc. are generally required with flame retardant effect.In addition non-flammable adhesive tape navigates in space flight
Also there is extensive purposes in empty field.
For the pressure sensitive adhesive glue of halogen-free flameproof, in order to reach good flame retardant effect, a large amount of resistance is usually added
Agent is fired, but after fire retardant is added, the peeling force of glue will receive very big influence.As introduced in patent CN103865449B
Flame-retardant glue, although peeling force can be more than 10 Ns/inch, self-extinguishing time cannot reach many clients at 10 seconds or so
It is required that be lower than requirement in 5 seconds；The flame-retardant glue for another example introduced in patent CN101805567A, although self-extinguishing time 5 seconds with
Under, peeling force can only achieve the intensity of 5 Ns/inch.
To solve the above-mentioned problems, we are made that a series of improvement.
Summary of the invention
The object of the present invention is to provide a kind of flame-proof acrylic pressure sensitive adhesives and preparation method thereof, to overcome the prior art
Existing disadvantages mentioned above and deficiency.
A kind of flame-proof acrylic pressure sensitive adhesive, which is characterized in that the acrylate pressure sensitive adhesive is acrylate polymer, packet
It includes: Isooctyl acrylate monomer, vinylacetate, hydroxy-ethyl acrylate, glycidyl acrylate, azodiisobutyronitrile and acetic acid second
Ester, the fire retardant of the acrylate polymer are halogen-free flame retardants, and the mass fraction of the halogen-free flame retardants is 5~10 parts；
The mass fraction of its each component are as follows:
