Abstract
The invention relates to the technical field of plastic production and especially relates to impact-resistant stretch-resistant plastic. The impact-resistant stretch-resistant plastic comprises, by weight, 80-100 parts of PVC resin, 8-20 parts of light calcium carbonate, 15-30 parts of block polyisocyanate, 5-15 parts of dipropylene glycol dimethyl ether, 15-25 parts of organosilicone-modified polyurethane resin and 10-20 parts of deionized water. The PVC resin resists impact, stretch, aging, embrittlement and deformation and satisfies product special performance requirements.
Description
Technical field:
The present invention relates to plastic cement production technical field, refer in particular to a kind of Shock-resistant stretch-proof plastic cement.
Background technology:
Shock-resistant stretch-proof plastic cement is most widely used polymer.It has good physics
And mechanical performance, impact strength is higher, and chemical stability, electrical property are good, finished product processing,
Machining property is good, and water-fast, inorganic salt, soda acid, is that one can be wide variety of
Engineering material.But current resin plastic cement yet suffers from, and intensity is low, abrasion-resistant surface is poor,
Under extreme case, flame-proof heat-resistant performance is not strong, the shortcoming of surface gloss difference.
Summary of the invention:
It is an object of the invention to for the deficiencies in the prior art, and provide that a kind of shock resistance is resistance to draws
Stretching plastic cement, the present invention solves prior art existing problems, uses polyvinyl chloride resin, shock resistance
Stretch-proof, be difficult to aging, be difficult to become fragile, be unlikely to deform, meet the need of product property
Want.
For achieving the above object, the present invention adopts the following technical scheme that, a kind of Shock-resistant stretch-proof
Plastic cement, including the component of following percentage by weight:
Polyvinyl chloride resin 80-100 part；
Precipitated calcium carbonate 8-20 part；
Polyisocyanate block thing 15-30 part；
Dimethyl ether 5-15 part；
Organic silicon modified polyurethane resin 15-25 part；
Deionized water 10-20 part.
The preparation method of described a kind of Shock-resistant stretch-proof plastic cement, it comprises the following steps:
A) weighed polyvinyl chloride resin, precipitated calcium carbonate, polyisocyanate block thing by formula, had
Machine silicon modified polyurethane resin is in a mixing bowl；
B) weigh the deionized water of corresponding proportion, be heated to 80 ± 10 DEG C, point 2-4 addition
With a mixing bowl of propeller, often add and once stir 2-10min, until adding completely；
C) mixing stirring: after all raw materials add, propeller is with 800-1200 rev/min turn
Speed stirring 15min-30min；
D) extruder extrusion；
E) pelletizing；
I.e. make a kind of Shock-resistant stretch-proof plastic cement.
Present invention have the beneficial effect that Shock-resistant stretch-proof, be difficult to aging, be difficult to become fragile, no
Yielding, meet the needs of product property.
