Halogen-free rubber-plastic product and preparation method thereof

Abstract

The invention relates to a halogen-free rubber-plastic product and a preparation method thereof. The halogen-free rubber-plastic product comprises the following components by weight: a dispersing agent HT-5168, calcium stearate, polyethylene glycol, an anti-aging agent 4020, activated zinc oxide, sulfur powder, solid paraffin, antimony trioxide, zinc borate, nitrile rubber, aluminum hydroxide, polyvinyl chloride resin, dioctyl ester, epoxidized soybean oil, carbon black N550, azodicarbonamide and rubber accelerating agent. The halogen-free rubber-plastic product is simple and convenient in preparation process and low in production cost, and the rubber-plastic product performance, the flame-retardant performance and the using safety performance can be combined.

Description

[0001] technical field [0002] The invention relates to a rubber and plastic product, in particular to a halogen-free rubber and plastic product and a preparation method thereof. [0003] Background technique [0004] Halogen-containing polymers or flame-retardant mixtures combined with halogen-containing flame retardants have excellent flame-retardant properties and have been widely used as flame-retardant materials. However, when a fire occurs, such halogen-containing flame-retardant materials will produce a large amount of smoke and toxic corrosive hydrogen halide gas, causing secondary hazards. In February 2003, the European Union promulgated RoHs (The Restriction of Hazardous Substances in Electrical and Electronic Equipment, Directive 2002 / 95 / EC) and WEEE (Waste Electric and Electronic Equipment, Directive 2002 / 96 / EC) two directives , the former is an instruction on the restriction and prohibition of the use of certain toxic and hazardous substances and elements...

Problems solved by technology

[0005] Most of the rubber and plastic materials on the market are combustible or flammable rubber types, which have potential fire safety hazards

In order to improve the flame retardant properties of rubber and plastic materials, halogenated flame retardants are traditionally added during the refining process of rubber and plastic materials. This type of rubber and plastic materials will produce dioxins when they are flame retardant, and dioxins can exist in the environment for many years. It can even be accumulated in organisms for life and cannot be discharged. At the same time, the toxic gas containing dioxin can easily make it difficult for personnel to escape, and the flame retardancy and use safety performance is low.

At present, antimony trioxide and hydroxide are used as flame retardants for rubber and plastic materials to increase their environmental protection and safety performance. When burning, the amount of smoke is small and no toxic or corrosive gases are produced, but the amount of flame retardant that needs to be added Larger, it is easy to increase the difficulty of rubber refining and reduce the performance of the rubber compound. At the same time, some flame retardants are expensive and not suitable for industrial mass production.
