High compatibility modifier for plastic processing

Abstract

The invention provides a high compatibility modifier for plastic processing. The high compatibility modifier for plastic processing comprises, by weight parts, 5-15 parts of nano calcium carbonate, 5-10 parts of chlorinated polyethylene, 5-10 parts of silicone acrylic emulsion, 2-5 parts of dimethicone copolyol, 0.5-2 parts of grafted polyether polyol, 3-10 parts of polyethylene glycol, 0-1 part of ethyl p-aminobenzoate, 0-1 part of heat stabilizer, 0-1 part of coupling agent and 0-0.5 part of surfactant. Through the reasonable raw material ratio, the made modifier has excellent dispersibilityand compatibility for plastic processing and improves plastic product quality stability. In addition, the high compatibility modifier also has excellent weather resistance, UV resistance and toughness, the comprehensive quality is obviously improved, the practical benefit is improved, and the high compatibility modifier is worth promoting.

Description

technical field [0001] The invention relates to the technical field of plastic processing aids, in particular to a highly compatible modifier for plastic processing. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose synthetic resins in synthetic materials, and its output is second only to polyethylene, ranking second. PVC is one of the most widely used plastics in the world. Only half of the raw material comes from petroleum, and the other half comes from rich ore, so it is widely used in construction industry, packaging materials, household daily necessities and automobile industry. However, the recycling problem of PVC and the potential impact on the environment have not been solved, and the restrictions on PVC still exist in many occasions. Therefore, attention must still be paid to the application development and recycling of PVC. At present, in order to reduce the industrial hazards of PVC plastics as much as possible, most PVC ...

AI Technical Summary

Problems solved by technology

In order to overcome the disadvantages of poor flexibility, high brittleness and poor impact resistance of plastic products, it is generally necessary to add plasticizers, tougheners, anti-impact agents, lubricants and other modifiers

For the processing of recycled engineering plastics, the performance requirements for modifiers must be higher. However, most of the existing modifiers have single functions and only have a certain function. Therefore, in the production process of a plastic product, it often needs Adding a variety of modifiers will virtually increase the cost of the product, not to mention the low utilization rate of raw materials and the poor performance of each modifier. Most of the performance improvement effects are poor, and the timeliness is short. The overall quality Difference

In addition, the existing modifiers contain a variety of additives with different performance improvement requirements. In the plastic production process, when used, there are problems of mutual antagonism, poor dispersion, and low utilization rate, which greatly affects the modification. Therefore, it is necessary to design a plastic processing modifier with comprehensive performance modification, high degree of coordination between raw materials, and good comprehensive compatibility and dispersion.
