Technical field
The present invention relates to a kind of resins and preparation method thereof.Specifically, it is lotion used in artificial leather preparation process ----
Corvic and preparation method thereof.
Background technology
It is both known about in chemical industry, as the polrvinyl chloride product of artificial leather etc is mostly by fabric and to be compounded in fabric table
Face lotion drying after formed surface layer and constitute.Lotion therein is polyvinyl chloride.And vinyl chloride mobility is poor, therefore
It needs that modifier is added in process of production to promote its plasticizing, it is comprehensive with the appearance for improving its mobile performance and artificial leather product
Close performance.In addition, being formed in the surface layer of fabric surface with polyvinyl chloride has the characteristics that black brittleness, shock resistance are poor.Cause
In process of production, and anti-impact modifier need to be added to improve its shock resistance in this.Wherein, the processing of polyvinyl-chloride use changes
Property agent be esters of acrylic acid（ACR）, anti-impact modifier is haloflex（CPE）, methyl methacrylate-butadiene-benzene
Ethylene（MBS）And esters of acrylic acid（ACR）.And above-mentioned esters of acrylic acid（ACR）, haloflex（CPE）And methacrylic acid
Methyl esters-butadiene-styrene（MBS）It is expensive so that the production cost of polrvinyl chloride product is higher.
Invention content
The problem to be solved in the present invention is to provide a kind of vinyl chloride high polymer.This vinyl chloride high polymer, raw materials used valence
Lattice are cheap, and production cost is low.The polrvinyl chloride product made of this vinyl chloride high polymer, shock resistance are good.
The invention solves another problem be to provide a kind of method preparing vinyl chloride high polymer.
The invention solves the above problem realized by following scheme：
The vinyl chloride high polymer feature of the present invention is made of following raw material：

The dispersant is with polyvinyl alcohol and polyvinylpyrrolidone methylcellulose graft copolymer and according to polyethylene
Alcohol：Polyvinylpyrrolidone methylcellulose graft copolymer=1:3 weight ratio mixes；；
The method for preparing the vinyl chloride high polymer includes the following steps successively：
First molecular weight regulator, initiator, dispersant and deionized water are added in reaction kettle, while agitating, to reaction
Kettle is vacuumized, and dispersant is made fully to dissolve；
While continuing stirring, vinylacetate is added；Later, the 1/2-2/3 of vinyl chloride is added, and continues to stir 20-30
Minute, keep starting material pre-dispersed；
Later, reaction kettle is heated, so that the material in reaction kettle is warming up to 40-60 degrees Celsius and is reacted；Work as reaction kettle
It is continuous in 2.9 ~ 3.1 hours, be homogeneously added into acrylic ester monomer and remaining chloroethene when interior pressure reduction 0.2MPa
Alkene；
When the pressure in reaction kettle is down to 0.25MPa or less, the temperature of charge in reaction kettle is risen to 70-75 degrees Celsius, and
Keep the temperature 1-2 hours at this temperature；
Later, the material in reaction kettle is poured out and is dehydrated；
Later, to being washed through dewatered material；
Later, second dehydration is carried out to the material after washed；
Later, with 40-50 DEG C of hot wind to being dried into the material through second dehydration；
Finally, the material after drying is sieved with the sieve of 40 mesh, vinyl chloride high polymer is made.
As can be seen from the above scheme, due to primary raw material vinyl chloride, vinylacetate and the acrylic acid of the invention used
Esters monomer is cheap, thus greatly reduces the production cost of polrvinyl chloride product.And the good, anti-impact with processing performance
Hit the excellent feature of performance.In addition, also have the characteristics that it is fire-retardant, insulation, it is corrosion resistant, have wide range of applications.In addition, as a result of
Suspension polymerisation, and the advantages of combine in synthesis nucleocapsid and reticular structure, overcome the chlorine of other synthesis modes preparation
Ethylene copolymer technical maturity is low, auxiliary agent, emulsifier residual is more, product purity is not high, processing performance is bad, impact resistance
Disadvantage that can not be strong.
