Porcelainized polyolefin composite material and preparation method thereof

Abstract

The invention discloses a porcelainized polyolefin composite material, comprising the following raw materials in parts by weight: 50-100 parts of polyolefin resin, 10-200 parts of porcelainized powder, 0.1-50 parts of an accelerant, 0-100 parts of a fire retardant, 0.3-15 parts of a compatilizer, 0.2-10 parts of a coupling agent, 0.1-5 parts of a lubricant and 0.1-8 parts of an antioxidant. The porcelainized polyolefin composite material disclosed by the invention is simple in technological process, easy to operate, free of three wastes, and excellent in mechanical property and electric property, and can be sintered into ceramic at a temperature over 600 DEG C or in a flame within 5-10 minutes; and the formed shell is good in integrity, free of cracking or drippage, has excellent fireproof performance and heat-insulating property, and has high application value in the fields of fire-resistant wires and cables and indoor fire-resistant decoration.

Description

technical field [0001] The invention relates to a polyolefin composite material and a preparation method thereof. Background technique [0002] With the development of society and economy and the advancement of science and technology, polymer materials are playing an increasingly important role in the construction of the national economy and are widely used in many fields such as people's daily life, aerospace and military. The country's fire-resistant requirements for wires and cables and interior decoration materials in public places are getting higher and higher, and the fields involved are becoming wider and wider, and the market potential of fire-resistant polymer materials is gradually showing. Especially in the field of national defense and military affairs, fire-resistant polymer materials are of great significance for ensuring the safety of power supply and equipment protection in case of abnormal fire.

Problems solved by technology

[0003] In the cable industry, the mineral insulated fire-resistant cables in the past are gradually being replaced by the emerging ceramic silicone rubber flexible fire-resistant fire-resistant cables. However, due to the poor mechanical properties and scratch resistance of ceramic silicone rubber, it is used as Restricted when used over the outer sheath of a cable or directly on the sheath of a wire

In the field of interior decoration materials, the current main direction is to improve the flame retardant properties of materials, but high flame retardant materials must add a large amount of flame retardants or high-performance flame retardants, so there are poor mechanical properties of materials or high costs. problem, it is more difficult to popularize
