Abstract
The invention relates to an assistant capable of improving the ageing resistance of a PVC (polyvinyl chloride) film. The assistant comprises raw materials in parts by weight as follows: 20 parts of diethyl phthalate, 18 parts of phosphite ester, 12 parts of epoxidized soybean oil, 12 parts of calcium carbonate, 7 parts of polycarbonate, 3 parts of a calcium-zinc stabilizer and 3 parts of lemon glycoside. By means of the assistant, the thermal ageing resistance of the PVC film can be improved, and the ageing time of the PVC film can be prolonged.
Description
Technical field
The present invention relates to plastics technology field, relate in particular to a kind of auxiliary agent of the PVC of raising film ageing-resistant performance.
Background technology
PVC film obtains widespread use as a kind of synthetic materials, but PVC film in processing, be easily heated in use procedure, the effect of light, oxygen produces degraded, there is usually said catabiosis, this is a large defect of PVC film, and the ageing-resistant performance that therefore improves PVC film is the important content of current scientific research.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of auxiliary agent of the PVC of raising film ageing-resistant performance is provided.
The technical solution used in the present invention is as follows, improve an auxiliary agent for PVC film ageing-resistant performance, this auxiliary formula is comprised of the raw material of following weight part: 20 parts of diethyl phthalates, 18 parts of phosphorous acid esters, 12 parts of epoxy soybean oils, 12 parts, calcium carbonate, 7 parts of polycarbonate, 3 parts of calcium zinc stabilizers, 3 parts of limonins.
Advantage of the present invention is: auxiliary agent of the present invention can improve the thermal ageing resistant performance of PVC film and the digestion time that extends product.
Embodiment
Be below several specific examples of the present invention, further describe the present invention, but the present invention be not limited only to this.
