High-strength plastic

Abstract

The invention relates to high-strength plastic, which comprises the following components in percentage by weight: 18-24 percent of PA66, 4-6 percent of PA6, 8-13 percent of organic silicon modified bisphenol A epoxy resin, 0.1-0.3 percent of an antioxidant, 0.8-1.0 percent of a coupling agent, 0.1-0.3 percent of a lubricating agent and 60-65 percent of organic silicon modified bisphenol A epoxy resin.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a high-strength plastic. Background technique [0002] Since environmental issues have been paid more and more attention, the energy consumed by steel production is huge, and the proportion of steel is relatively high, especially in some rotating parts of vehicles and motors, and the basic power consumed to drive them is also relatively small. high. [0003] To this end, engineers have been looking for lightweight, high-strength alternatives. In this regard, polymer materials have become the preferred target due to their small specific gravity, which is only about one-third of that of steel in the same volume. After years of development, some high-strength engineering plastics have been developed and applied to the market. When these engineering plastics are used in motor vehicles, the weight reduction is also an important factor in reducing emissions, especially in the automo...

Problems solved by technology

But in this way, although the strength is enhanced, the toughness is relatively reduced, especially in the event of a collision, it is easy to be affected by the shear force and cause fractures or cracks.

At the same time, the surface adsorption of these high-strength plastics is low, and the binding force with the paint is not high, resulting in little color change, which cannot meet people's requirements.
