Abstract
The invention relates to a 60% high solid content pressure-sensitive adhesive and a preparation method thereof, and discloses a way for obtaining environment-friendly pressure-sensitive adhesive whichis applicable to manufacturing a surface protective film of building materials, electrical and electronic products, machines, furniture and the like. The pressure-sensitive adhesive is prepared by adopting a semi-continuous seed emulsion polymerization, taking butyl acrylate, methyl methacrylate, hydroxy-ethyl acrylate and acrylic acid as monomers, synchronously adding mixed emulsifying agent formed by anionic emulsifying agent and nonionic emulsifying agent as well as mixed liquid formed by initiating agent and ammonium persulphate, and having polymerization reaction in subacid deionized water. The pressure-sensitive adhesive has no emission of noxious and harmful substances when in production and use, so as to purify the environment. Meanwhile, the protective film and base material produced by the pressure-sensitive adhesive has better combination, do not damage the surface of the protected object, and can be torn off from the surface of the protected object so as to leave no residual trace.
Description
Affiliated technical field
The invention belongs to chemical technology field, is a kind of high solids content environment friendly pressure sensitive, and it is applicable to the manufacturing of surface protection films such as building materials, electric equipment products, shape, machinery, furniture.
Background technology
Since long term, protective membrane is made used glue and mostly is the solvent-borne type pressure sensitive adhesive, and because of poisonous, the deleterious organic compound of solvent polyphyly commonly used, therefore existing solvent-borne type pressure sensitive adhesive contaminate environment damages human body, and its price height.Though existing market has minority environmental protection pressure sensitive adhesive to occur, their solid content is unfavorable for low cost production far below 60%, and the viscosity that has is higher, and levelling property is bad, and what have is not good enough with the consistency of certain base material again, causes difficulty.Existing in a word pressure sensitive adhesive all is difficult to the effect that reaches satisfied.
Summary of the invention
The objective of the invention is to overcome the defective of existing pressure sensitive adhesive, provide a kind of solid content up to 60%, and viscosity is lower, good with the adaptability of base material, especially can in the process of making protective membrane, guarantee pollution-free, harmless pressure sensitive adhesive.
The objective of the invention is to realize by following technical measures: this 60% high solid content pressure-sensitive adhesive is to adopt the semi-continuous seed emulsion polymerization method, with acrylic acid butyl ester, methyl methacrylate, Hydroxyethyl acrylate, vinylformic acid is monomer, add synchronously by anionic emulsifier and nonionic emulsifying agent and form the mixed solution that blending emulsifiers and initiator ammonium persulfate are formed, and in slightly acidic deionized water, be polymerized.Its prescription is as follows by weight percentage:
Butyl acrylate 48-54%
Methyl methacrylate 3-6%
Hydroxyethyl acrylate 0.6-3%
Vinylformic acid 0.6-3%
Blending emulsifiers 0.6-4.2%
Ammonium persulphate 2.4-5.4%
The deionized water surplus
Described blending emulsifiers is by weight by the anionic emulsifier sodium lauryl sulphate: nonionic emulsifying agent sim alkylphenol Soxylat A 25-7 is to mix at 2: 1.The pH value of described deionized water should be 6-7.
Preparation process of the present invention is to get each raw material ready by above-mentioned recipe ratio earlier to be undertaken by following processing step:
(1) by in the recipe ratio, remove the 18-20% of ionized water gross weight, the 20-25% of blending emulsifiers gross weight stirs in the 10% adding reactor of each total monomer weight;
When (2) being warming up to 75-81 ℃, by getting 50% of ammonium persulphate gross weight in the recipe ratio, and it is mixed with after weight percent concentration is 10% ammonium persulfate solution, is added dropwise to reactor;
(3) after ammonium persulphate drips, be incubated 1 hour, again with remaining each monomer and remaining blending emulsifiers, to be made into weight percent concentration by remaining ammonium persulphate be 10% ammonium persulfate solution, and remaining deionized water drips synchronously, is warming up to 80-85 ℃ after dripping off again;
(4) insulation was reduced to room temperature after 1 hour;
(5) regulate pH value to 6-7 with ammoniacal liquor;
(6) add defoamer, its consumption till the visual inspection lather collapse, filter the back product.
The present invention's beneficial effect compared to existing technology is: no matter in the production of this pressure sensitive adhesive, also or the manufacturing of derived product protective membrane and use in all do not have poisonous, discharge of poisonous waste, environment is purified.The protective membrane of being made by this pressure sensitive adhesive combines with base material better simultaneously, does not damage the protected object surface, is not corroded as metallic surface.When not needing protection, easily take off, and the protection body surface can remaining trace from the protection body surface.
