Abstract

The preparation method that the invention discloses a kind of PVC paste resin, comprise the following steps: emulsifying agent and deionized water are sequentially added in reactor, stir, adjust solution ph to 8.5~9, then being sequentially added into initiator and vinyl chloride, stir, controlling reactor temperature is 90 DEG C~100 DEG C, polyreaction 1.5 hours~2 hours, obtains PVC paste resin.The PVC paste resin foam performance prepared according to the inventive method is good, becomes to stick with paste function admirable, and product stability is better.

Description

The preparation method of PVC paste resin
Technical field
The present invention relates to chemical industry resin technology field, the preparation method of especially a kind of PVC paste resin.
Background technology
PVC paste resin is a kind of unique liquid form of the igelite under rough, and its granularity is fine, the similar Pulvis Talci of quality, has nonflowing character.PVC paste resin is agitated to form stable suspension after mixing with plasticizer, namely makes PVC paste material.
PVC paste resin prepares mainly through emulsion method and microsuspending method, the production of PVC paste resin all needs to add emulsifying agent and diversion agent, the selection of emulsifying agent and diversion agent and formula are all very crucial, directly influence production cost and product quality, for this, this is all conducted in-depth research by many documents and patent.
Summary of the invention
The preparation method that it is an object of the invention to provide a kind of PVC paste resin, this method adopts sucrose fatty acid ester or dodecylbenzene sodium sulfonate as emulsifying agent, using azodiisobutyronitrile as initiator, it is possible to the problem solving product stability difference.
In order to solve the problems referred to above, the technical solution used in the present invention is: the preparation method of this PVC paste resin, comprise the following steps: first emulsifying agent and deionized water are sequentially added in reactor, stir, adjust solution ph to 8.5~9, be then sequentially added into initiator and vinyl chloride, stir, controlling reactor temperature is 90 DEG C~100 DEG C, and polyreaction 1.5 hours~2 hours obtains PVC paste resin.
In technique scheme, scheme can also make more specifically: emulsifying agent adopts sucrose fatty acid ester or dodecylbenzene sodium sulfonate.
Further, initiator adopts azodiisobutyronitrile.
Further, vinyl chloride, emulsifying agent, the mass ratio of deionized water and initiator is 1:0.1~0.15:1.5~2:0.05~0.1.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
The present invention adopts sucrose fatty acid ester or dodecylbenzene sodium sulfonate as emulsifying agent, and using azodiisobutyronitrile as initiator, prepared PVC paste resin foam performance is good, becomes to stick with paste function admirable, and product stability is better.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
Embodiment 1
150 grams of sucrose fatty acid ester and 1.5 kilograms of deionized waters are sequentially added in reactor, stir, adjust solution ph to 8.5~9, then 50 grams of azodiisobutyronitriles and 1 kilogram of vinyl chloride it are sequentially added into, stir, controlling reactor temperature is 90 DEG C, and polyreaction 2 hours obtains PVC paste resin.
Embodiment 2
1 kilogram of sucrose fatty acid ester and 12.5 kilograms of deionized waters are sequentially added in reactor, stir, adjust solution ph to 8.5~9, then 1 kilogram of azodiisobutyronitrile and 10 kilograms of vinyl chloride it are sequentially added into, stir, controlling reactor temperature is 90 DEG C, and polyreaction 2 hours obtains PVC paste resin.
Embodiment 3
6.25 kilograms of sucrose fatty acid ester and 50 kilograms of deionized waters are sequentially added in reactor, stir, adjust solution ph to 8.5~9, then 3.75 kilograms of azodiisobutyronitriles and 50 kilograms of vinyl chloride it are sequentially added into, stir, controlling reactor temperature is 90 DEG C, and polyreaction 2 hours obtains PVC paste resin.
