Description

The nontoxic uvioresistant sheet material of a kind of PVC hard

Technical field

The present invention relates to a kind of sheet material, be specifically related to the nontoxic uvioresistant sheet material of a kind of PVC hard.

Background technology

Publication No. is the Chinese invention patent of CN 103131099 A, it discloses a kind of anti-ultraviolet PVC sheet, toxic substance can be prevented after being subject to uviolizing, but degree of aging is very fast in this sheet material use procedure, tensile strength is general, especially cold-resistant degree is poor, when sheet material lower ground just uses in temperature, easily occurs slight crack.Contriver improves on the basis of original formula, to overcome described defect.

Summary of the invention

The object of the present invention is to provide a kind of shock resistance, anti-aging, cold-resistant, the seamless nontoxic uvioresistant sheet material of PVC hard.

For achieving the above object, the present invention adopts following technical scheme:

The nontoxic uvioresistant sheet material of a kind of PVC hard, is made up of following material per-cent: PVC resin-oatmeal 55-65%; EVA ethene-vinyl acetate copolymer 13-20%; LLDPE linear low density polyethylene 2-8%; PETG2-8%; MPE2-7%; Thiol methyl tin 0.5-5%; Toughener 0.5-5%; Stablizer 0.5-5%; Processing aid 0.5-4%; Calcium stearate 0.5-4%; Internal lubricant 0.1-3%; External lubricant 0.1-3%; Tinting material 0.1-3%.

As preferred technical scheme: PVC resin-oatmeal 60%; EVA ethene-vinyl acetate copolymer 16%; LLDPE linear low density polyethylene 4%; PETG4%; MPE3.5%; Thiol methyl tin 2.5%; Toughener 2.5%; Stablizer 2.5%; Processing aid 1.5%; Calcium stearate 1.5%; Internal lubricant 0.5%; External lubricant 0.5%; Tinting material 1%.

The invention has the advantages that: EVA ethene-vinyl acetate copolymer improves the snappiness of product, shock resistance; LLDPE linear low density polyethylene adds the sticking power of later stage ink and colloid, the problem avoided deinking and come unstuck; The use of MPE can improve the tensile strength of sheet material.Comprehensive obtain a kind of shock resistance, anti-aging, resist cold, the seamless nontoxic uvioresistant sheet material of PVC hard, especially stretch-proof and cold-resistant in, achieve excellent effect especially.

embodiment:

adopt preparation method as follows in embodiment,

1) calendering stage;

Mainly comprise: batching, heat agitated, cold stirring, extrude, press saliva, stripping, press polish, cooling, traction;

PVC resin-oatmeal 63%; EVA ethene-vinyl acetate copolymer 18%; LLDPE linear low density polyethylene 3%; PETG3%; MPE4%; Thiol methyl tin 1.5%; Toughener 1.5%; Stablizer 1.5%; Processing aid 0.9%; Calcium stearate 0.6%; Internal lubricant 1%; External lubricant 1%; Tinting material 1%.

Implement two:

PVC resin-oatmeal 55%; EVA ethene-vinyl acetate copolymer 14%; LLDPE linear low density polyethylene 6%; PETG4%; MPE3%; Thiol methyl tin 3%; Toughener 4%; Stablizer 4%; Processing aid 2%; Calcium stearate 2%; Internal lubricant 1%; External lubricant 1%; Tinting material 1%.

Implement three:

PVC resin-oatmeal 60%; EVA ethene-vinyl acetate copolymer 16%; LLDPE linear low density polyethylene 4%; PETG4%; MPE3.5%; Thiol methyl tin 2.5%; Toughener 2.5%; Stablizer 2.5%; Processing aid 1.5%; Calcium stearate 1.5%; Internal lubricant 0.5%; External lubricant 0.5%; Tinting material 1%.

Following table is patent test data contrast situation involved by the embodiment of the present invention and background technology:
