Description
Technical field
The present invention relates to a kind of ageing-resistant PVC plastic formula.
Background technology
PVC work in-process needs to add auxiliary agent, the plastic products such as various soft, hard, transparent, the electrical isolation meeting people's needs is good, foaming can be obtained, in the preparation process of PVC plastic, the whiteness of plastic product is improved by adding the additives such as titanium dioxide, zinc white, white dyes, after long-time use, because uviolizing can cause the photoaging of material, make material aging variable color.
Summary of the invention
For the problems referred to above, the invention provides a kind of ageing-resistant PVC plastic formula, improve the ageing-resistant of PVC plastic finished product and anti-look change ability.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of ageing-resistant PVC plastic formula, it is characterized in that, its raw material consists of:
Polyvinyl chloride resin: 800-900 part;
Light active calcium carbonate: 80-90 part;
Zinc oxide: 50-55 part;
Rare-earth stabilizer: 25-28 part;
Titanium dioxide: 30-35 part;
White dyes: 0.5-1 part;
Hindered amine as light stabilizer: 10-18 part;
Chlorinatedpolyethylene: 60-70 part;
Acrylate: 15-20 part;
Above-mentioned number is mass fraction.
Preferably, described polyvinyl chloride resin is PVC-SC5 resin or PVC-SG4 resin.
Preferably, also comprise the blue 0.3-0.5 part of group cyanines, described number is mass fraction.
Preferably, 2-hydroxyl-4-octyloxybenzophenone or single phenylformic acid resorcinol is also comprised.
By adding multiple auxiliary agent in polyvinyl chloride resin, such as rare-earth stabilizer, hindered amine as light stabilizer, 2-hydroxyl-4-octyloxybenzophenone or single phenylformic acid resorcinol can produce good light stabilising effect to PVC product, effectively avoid ultraviolet loss, improve the ageing-resistant of PVC plastic finished product and anti-look change ability.
The invention has the beneficial effects as follows: formula is simple, low cost of manufacture, effectively can improve the ageing-resistant of PVC plastic finished product and anti-look change ability.
