Special reinforced polypropylene functional resin for ABS ( Acrylonitrile Butadiene Styrene) and modified ABS resin

Abstract

The invention relates to special reinforced polypropylene functional resin for ABS (Acrylonitrile Butadiene Styrene) and modified ABS resin. The special reinforced polypropylene functional resin for the ABS is prepared from polypropylene and acrylate monomers, wherein the polypropylene is subjected to irradiation through an electron accelerator; the energy level of the electron accelerator is 3.0MeV, the irradiation dosage is 100 to 300KGy, and the irradiated polypropylene is mixed with the acrylate monomers. The special reinforced polypropylene functional resin for the ABS and the modified ABS resin disclosed by the invention have the beneficial effects that the a certain proportion of acrylate monomers (AA) are added into a polypropylene powder material, the irradiation is carried out byadopting the 3.0 electron accelerator, and grafted reaction on the monomers and the polypropylene is carried out, so that the reinforced polypropylene functional resin is obtained, and therefore, thepolarity of the product is greatly improved; the reinforced polypropylene functional resin as a base material is applied to the ABS resin or a blend filled with the enhanced composite material and the polypropylene, so that the compatibility and the interface bonding degree of the material can be obviously improved, thereby improving the comprehensive performance of the material.

Description

technical field [0001] The invention belongs to the field of resin processing, and in particular relates to a special reinforced polypropylene functional resin for ABS and a modified ABS resin. Background technique [0002] ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size, and good surface gloss. It is easy to paint. , coloring, and secondary processing such as surface metal spraying, electroplating, welding, hot pressing and bonding, etc. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles and construction. Wide range of thermoplastic engineering plastics. [0003] In ABS resin, rubber particles are dispersed phase, dispersed in the continuous phase of SAN resin. Just because the continuous phase is SAN r...

AI Technical Summary

Problems solved by technology

In the common ABS high rubber powder, the butadiene content is 55-70%, the rubber particles are in the continuous phase, and the rubber particles are wrapped with the SAN resin in the dispersed phase, so that the apparent performance of the high rubber powder is dominated by butadiene, with Elasticity, the solubility parameter is between 9.0-9.3, which is closer to the solubility parameter of polybutadiene (8.2-8.5), and the apparent polarity is poor

[0005] Although the composition monomers of ABS resin and ABS high rubber powder are consistent and have certain compatibility, when the addition amount of ABS high rubber powder is less than 5%, the impact resistance can be effectively improved, but due to the large difference in solubility between the two Large, with different apparent polarities. When the amount of ABS high-grade rubber powder added is greater than 5%, the dispersed rubber particles will aggregate into a stem tape, and local phase delamination occurs. With the increase of high-grade rubber powder, the phase The delamination phenomenon will be more serious, resulting in poor effect of enhancement, and even affecting the overall performance of the material
