Abstract
The invention discloses a special blow-molding resin for automobiles and a preparation method thereof. The special blow-molding resin for automobiles is prepared from the following raw materials in parts by weight: 15-90 parts of resin, 1-17 parts of glacial acetic acid, 1-20 parts of calcium carbonate, 1-20 parts of cold-resistant flexibilizer and 1-20 parts of environment-friendly antimicrobial agent. The invention aims to overcome the defects in the prior art. The preparation method comprises the following steps: heating the resin to 90-110 DEG C, spraying the glacial acetic acid on the heated resin, quickly cooling to normal temperature, adding the calcium carbonate, cold-resistant flexibilizer and environment-friendly antimicrobial agent, uniformly mixing, carrying out polymerization reaction, and finally granulating. The formula proportion is adjusted to achieve the strength, toughness and cold resistance. Compared with the common resin, the strength of the modified material is enhanced by 20-50 times, the toughness is enhanced by 20-70 times, and the modified material can not generate brittle fractures at -100 DEG C. Thus, the special blow-molding resin for automobiles is very suitable for automobile industry, and has the advantages of high practical value and low cost.
Description
Technical field
The present invention relates to resin formula technical field, belong to a kind of automobile specified blowing grade resins and preparation method thereof.
Background technology
In recent years, along with the rapid growth of China's automobile pollution, the center of gravity of China's resin consumption market and application progressively shifts, and resin has at traffic and transport field to be applied very widely, and especially inner and outer decorative parts of automobile goods become the new consumption growth point of resin.Well-known resin has good mechanical property and excellent forming process characteristic, is widely applied in automobile industry.As the door-plate in automotive trim, dashboard, auxiliary fasia console, sun visor, the heat dissipation grid in automobile exterior, rear vision mirror, car light, license plate etc.
Existing ordinary resin strength ratio is lower, and toughness is not high, and simultaneously winter hardiness is poor, and be not suitable for automobile industry, although some high-grade resins meet the performance requriements of automobile industry, price comparison is high, is inapplicablely applied on low and middle-grade car.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of automobile specified blowing grade resins and preparation method thereof is provided, resin is heated to 90 DEG C-110 DEG C, Glacial acetic acid is sprayed on resin after the heating, rapid cooling is to normal temperature, add calcium carbonate, after cold-resistant flexibility agent and environment-friendly antibacterial agent mix, carry out polyreaction, last granulation, by adjustment formula rate, thus reach strength and toughness and resist cold, modified material, intensity compares ordinary resin increases 20-50 doubly, toughness improves 20-70 doubly, can when-100 degree, not embrittlement, be applicable to very much automobile industry to use, practical value is high, cost is low.
The present invention adopts following technical scheme to achieve these goals:
A kind of automobile specified blowing grade resins and preparation method thereof, is made up of the raw material of following weight part: resin 15 ~ 90 parts, 1 ~ 17 part, Glacial acetic acid, 1 ~ 20 part, calcium carbonate, cold-resistant flexibility agent 1 ~ 20 part, environment-friendly antibacterial agent 1 ~ 20 part.
Further, be made up of the raw material of following weight part: resin 60 parts, 16 parts, Glacial acetic acid, 14 parts, calcium carbonate, cold-resistant flexibility agent 12 parts, environment-friendly antibacterial agent 9 parts.
Further, described preparation method is: resin is heated to 90 DEG C-110 DEG C, is sprayed by Glacial acetic acid on resin after the heating, rapid cooling is to normal temperature, add after calcium carbonate, cold-resistant flexibility agent and environment-friendly antibacterial agent mix, carry out polyreaction, last granulation.
Compared with the prior art, beneficial effect of the present invention is as follows:
Automobile specified blowing grade resins of the present invention and preparation method thereof, according to the fat melting index variation of material, resize ratio can be carried out, thus reach strength and toughness and resist cold, modified material, intensity compares ordinary resin increases 20-50 doubly, and toughness improves 20-70 doubly, can when-100 degree, not embrittlement, be applicable to very much automobile industry to use, practical value is high, and cost is low.
