[0003] Patent CN109810371A invented a kind of ceramizable polyolefin oxygen barrier material, which uses polyolefin resin as the matrix, and blends and extrudes with flame retardant, ceramic powder, flux, coupling agent, lubricant and antioxidant Obtain an oxygen-insulated layer material, which can be sintered into porcelain at a temperature above 600°C, and has the function of heat and fire insulation. However, the disadvantage of this invention is that the temperature for forming porcelain is relatively high, and the strength of the formed porcelain body is relatively high. not enough, easy to drop
[0004] Patent CN107488294A invented a ceramic polyolefin cable material, which uses natural or porous layered aluminosilicates synthesized from natural clay as ceramic fillers, and polyolefin as a matrix material, so that ceramic polyolefin cable materials can be used in Porcelain is formed in a wide temperature range, but the invention has disadvantages such as insufficient strength of the formed porcelain body and complicated process
[0005] In short, the current ceramic polyolefin products on the market have problems such as insufficient strength of the sintered ceramic layer, and easy to fall due to slight vibration, which is not ideal for circuit protection in fire

Abstract

The invention discloses ceramic polyolefin with high ceramic forming strength and a preparation method thereof. The ceramic polyolefin with high ceramic forming strength is prepared from the following raw materials in parts by weight: 30-60 parts of polyolefin resin, 30-90 parts of ceramic powder, 10-30 parts of a flame retardant, 5-15 parts of a compatilizer, 0.1-5 parts of a smoke suppressant and 0.1-5 parts of an antioxidant. Polyolefin is selected as a base material, porcelain powder is added to prepare the composite material, green and environment-friendly tannin is introduced to serve as a flame retardant, the composite material has good flame retardant performance at low temperature, the tannin has the effect of an adhesive after being compounded with other flame retardants, a hydrogen bond network is established among filler particles, and the strength of a product is guaranteed; besides, in order to improve the damage to the processability or sintering performance caused by the addition of boron oxide or boric acid in a common method, boron carbide is added, so that the sintering speed and the compactness and strength of the formed ceramic are improved.

Description

Background technique [0002] Polyolefin has the advantages of high specific strength and good processability, and is widely used in various fields, but its flammable characteristics make it difficult to expand its scope of application, especially in the fields of wires and cables. cause a second disaster. In order to solve this hidden danger, technicians have developed ceramized polyolefin, which can form a ceramic layer at high temperature, so that the circuit can remain unblocked in a fire. [0003] Patent CN109810371A invented a kind of ceramizable polyolefin oxygen barrier material. The invention takes polyolefin resin as matrix, and is extruded by blending with flame retardant, ceramic powder, flux, coupling agent, lubricant and antioxidant. The oxygen barrier la...
