Preparation method of novel PVC modified additive acrylonitrile-chlorinated polyethylene-methyl methacrylate polymer
Technical Field
The invention belongs to the field of high polymer materials, and particularly relates to a preparation method of a novel PVC modified auxiliary agent acrylonitrile-chlorinated polyethylene-methyl methacrylate polymer.
Background
Acrylonitrile-chlorinated polyethylene-methyl methacrylate (AN-CPE-MMA) is a terpolymer formed by grafting AN and MMA monomers on CPE, and the terpolymer mainly overcomes the defect of insufficient performance of CPE and is developed into a high polymer material. Compared with CPE, ACM greatly improves the physical mechanical property and chemical property of CPE.
The ACM is produced by a bulk, solution and aqueous suspension swelling graft copolymerization method. The aqueous suspension swelling graft polymerization is adopted to prepare the ACM, the polymerization temperature and the particle form are easier to control in the polymerization process, the operation is simple and convenient, and the method is suitable for industrial application. Half of the existing production only adopts a single dispersant, and the dispersion effect in a water phase under a high temperature condition is not good, so that the characteristics of particles are influenced. By adopting a novel dispersion system and a polymerization technology, the dispersion effect in a water phase can be improved, and the particle characteristics of the product are optimized.
Disclosure of Invention
The invention aims to provide a preparation method of acrylonitrile-chlorinated polyethylene-methyl methacrylate, which is scientific, reasonable, simple and feasible, has high polymerization conversion rate, and the prepared product has excellent physical and mechanical properties, chemical properties and processing properties.
The preparation method of the acrylonitrile-chlorinated polyethylene-methyl methacrylate is prepared from the following raw materials in parts by weight:
2-14 parts of acrylonitrile
30-90 parts of chlorinated polyethylene
2-56 parts of methyl methacrylate
0.6 to 1.3 portions of composite dispersant
0.1 to 0.2 portion of water-soluble peroxide initiator
250 portions of deionized water and 500 portions of deionized water.
The composite dispersant is an organic dispersant and an inorganic dispersant, and the mass ratio of the organic dispersant to the inorganic dispersant is 1:2.2-2.2: 1.
The organic dispersant is one of polyvinyl alcohol, sodium dodecyl sulfate or cellulose ether.
The inorganic dispersant is one of calcium phosphate, magnesium sulfate or magnesium bicarbonate.
The water-soluble peroxide initiator is one of benzoyl peroxide, dicumyl peroxide or tert-butyl peroxybenzoate.
The raw materials also comprise an emulsifier; the addition amount of the emulsifier is 0.01-0.02 part by weight.
The emulsifier is one of octylphenol polyoxyethylene ether, sec-octylphenol polyoxyethylene ether or alkylphenol polyoxyethylene ether.
The preparation method of the acrylonitrile-chlorinated polyethylene-methyl methacrylate comprises the steps of mixing and dispersing the raw materials in a reactor, then swelling, carrying out polymerization reaction, separating and drying to obtain the acrylonitrile-chlorinated polyethylene-methyl methacrylate.
The swelling temperature is 20-40 ℃, and the swelling time is 0.5-2 h.
The polymerization temperature is 90-120 ℃, the polymerization pressure is 0.2-0.3Mpa, and the polymerization time is 2-8 h.
According to different ACM properties and purposes, the invention selects CPE with good fluidity, adjusts the content of the CPE in the product and the AN/MMA ratio, and obtains ACM products with good processing properties and different properties.
The AN-CPE-MMA graft copolymerization is carried out by adopting AN aqueous suspension polymerization method, and besides AN, MMA monomers and CPE, a polymerization system also contains a dispersing agent, AN initiator and AN emulsifier.
In order to improve the dispersion stabilizing effect, an organic/inorganic composite dispersant is adopted for polymerization, preferably, the organic dispersant is polyvinyl alcohol, and the inorganic dispersant is calcium phosphate. In order to achieve a small dispersion size of the inorganic dispersant in the polymerization system, it is advantageous to use the method as it is prepared before the polymerization and to add it directly in the form of an aqueous dispersion.
In order to improve the dispersibility of AN, CPE and MMA in the aqueous phase, AN emulsifier can be added on the basis of the addition of the organic/inorganic dispersing agent.
The preparation method of the acrylonitrile-chlorinated polyethylene-methyl methacrylate comprises the following steps:
before the polymerization starts, adding deionized water and a composite dispersing agent into a reactor, then adding CPE powder, starting stirring to disperse the CPE powder in a water phase, then adding AN and MMA monomers, a water-soluble peroxide initiator and AN emulsifying agent, and stirring for 0.5-1.0 h; raising the temperature to 20-40 ℃ to swell AN and MMA monomers into CPE for 0.5-2 h; then raising the temperature of the system to 90-120 ℃, introducing nitrogen to pressurize to 0.2-0.3Mpa, and polymerizing for 2-8h under the conditions of constant temperature, continuous temperature rise or stage temperature rise; and after the set polymerization time is reached, cooling to finish polymerization, and separating, washing and drying the polymerization product and the water phase to obtain the polymer.
The polymerization conversion rate of the invention is more than 90%, and the obtained ACM product has better physical and mechanical properties than CPE, and has better weather resistance and aging resistance than CPE.
Compared with the prior art, the invention has the following beneficial effects:
the invention is scientific, reasonable, simple and easy to operate, and the organic/inorganic composite dispersant is adopted, so that the dispersion effect is good, the dosage is small, the obtained ACM particles have good characteristics, and the post-treatment and the processing are easy; the proper peroxide initiator is selected, and a high-temperature constant-temperature, continuous-temperature-rise or gradual-temperature-rise polymerization process is adopted, so that the polymerization conversion rate is improved, the composition of the product is uniform, and the physical mechanical property, the chemical property and the processing property of the product are excellent.
