Abstract
The new-type polypropylene material with very low shrinkage consists of polypropylene, polyethylene, EPDM, mica powder, antioxidant, co-antioxidant, calcium stearate, coupling agent of organic titanate. The technological process of preparing the polypropylene material includes the steps of activating stuffing with coupling agent of organic titanate and mixing the materials in certain proportion at high temperature 80-100 deg.c inside high speed stirrer; pugging and pelletizing the mixture in a double-screw extruder; and shearing and kneading in re-combined two groups of shearing spiral blocks with medium shearing capacity 45 deg angle and three groups of kneading blocks. The material has shrinkage as low as 0.4-0.8 % and low cost.
Description
Technical field:
The present invention relates to a kind of novel polypropylene material, particularly relate to a kind of novel ultralow shrinking percentage polypropylene material; Belong to a kind of type material of automobile with decoration.
Background technology:
The decoration such as the car door anti-collision of present domestic automobile, collision bumper, dashboard, pay dashboard, instrument lid and require the assembling quality requirement precision and the exigent heater unit housing in fit-up gap, air filter housing, air-conditioner housing etc. now normally with ABS, ABS/PC or adopt PUR to add 30% glass fibre making decoration, the low-temperature impact resistance of its material, dimensional stability, moulding process, profile pattern require very high, select external material price costliness at present for use, the cost height.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of novel ultralow shrinking percentage polypropylene material, adopts current material cheap, in light weight, the lower temperature resistance excellence, and shrinking percentage can reach 0.4%-0.8%, impacts constantly in the time of-40 ℃.
Technical scheme of the present invention is achieved in that novel ultralow shrinking percentage polypropylene material, and its prescription (parts by weight) is: polypropylene 54-57.7; Polyethylene 1-5; Terpolymer EP rubber 10-20; Mica powder 30-40; Oxidation inhibitor 0.1-1; Auxiliary antioxidant 0.1-0.5; Calcium stearate 0.2-0.5; Titanate coupling agent CSC 0.31-5.Technological process is as follows:
1, filler is carried out activation treatment with titante coupling agent, then above various raw materials being put into temperature by prescription is 80-100 ℃ homogenizer, and through the homogenizer high-speed mixing;
2, treat behind the thorough mixing compound to be transported to two Luo bar forcing machines, carry out mixing granulator;
3, will shear Luo piece and pinch and to close the Luo piece and reconfigure, and pinch the Luo piece configuration of closing with two groups of shearing, three groups, 45 jiaos Luo piece of shear ability is sheared in the shearing Luo piece usefulness.
Positively effect of the present invention is: material price is cheap, as comparing with the PUR material of original employing, the little red flag car door anti-collision bar 4Kg/ car of this material produce, and crashproof of producing with type material is the 1.7Kg/ car, weight reduction reaches 42%, and be 6.5 ten thousand yuan/ton with the price of PUR, the price that promptly makes this product is: 65 yuan/Kg * 4Kg=260 unit/car; And with the price of type material be: 13.5 yuan/Kg * 1.7Kg=22.95 unit/car; Its material cost has reduced by 237.05 yuan/car, and the material cost reduced rate is 91%.And the lower temperature resistance excellence of this material is impacted constantly in the time of-40 ℃, and shrinking percentage can reach 0.8%.
