Embodiment 1

[0029] Example 1: Take the raw materials according to the components of the low-smoke halogen-free skeleton material described in Example 1 in Table 1 and their parts by weight; Then add it to the high mixer together with the rest of the components, stir at high speed for 5 minutes, feed into the internal mixer, and banbury for 10-15 minutes, until the banbury temperature reaches 130-135°C and discharge; then feed into the twin-screw In the extruder feeder, the temperature of the twin-screw extruder is 145°C-160°C, the feeding frequency is 30 Hz, and the main engine speed is 300 rpm; then it enters the single-screw extruder to extrude from the head, and then It is granulated by a granulator, and finally air-cooled to obtain a low-smoke and halogen-free skeleton material.

Embodiment 2

[0030] Embodiment 2: The raw materials are weighed according to the components and the parts by weight thereof in Embodiment 2 in Table 1, and other technological processes are the same as in Embodiment 1, and will not be repeated.

Embodiment 3

[0031] Embodiment 3: The raw materials are weighed according to the components of Embodiment 3 in Table 1 and the parts by weight thereof, and the other technological processes are the same as in Embodiment 1, and will not be repeated.

Abstract

Belonging to the technical field of new materials, the invention relates to a hydromagnesite, huntite and aluminum hydroxide composite synergistic flame retardant and smoke suppression low smoke halogen-free skeleton material. The low smoke halogen-free skeleton material is composed of the following components by weight: 10-20 parts of matrix resin A, 5-10 parts of matrix resin B, 15-30 parts of matrix resin C, 10-20 parts of a compatilizer, 40-60 parts of a flame retardant and smoke suppression agent, 0.5-2 parts of a coupling agent, 2-4 parts of a flow promoter, 0.5-2 parts of a lubricant, and 0.5-2 parts of an antioxidant. Specifically, the flame retardant and smoke suppression agent is a composite synergistic flame retardant and smoke suppression agent formed by hydromagnesite-huntite and aluminum hydroxide in a ratio of 1:1-2. The matrix resin A is an ethylene-vinyl acetate copolymer, the matrix resin B is an ethylene-octene copolymer, and the matrix resin C is polyethylene. The mechanical properties of the low smoke halogen-free skeleton material provided by the invention are improved, and at the same time the flame retardancy is also greatly enhanced.

Description

technical field [0001] The invention relates to a low-smoke, halogen-free frame material, in particular to a low-smoke, halogen-free frame material with a composite synergistic effect of flame retardancy and smoke suppression, and belongs to the technical field of new materials. Background technique [0002] In recent years, it has been found that more than 80% of the causes of death in fire accidents are related to the dense smoke and toxic gases produced by materials. With the rapid development of my country's modern industry, safety and prevention measures should be more and more perfect. In many large public places, in order to avoid the secondary disaster caused by cable fire (a large amount of smoke and acid gas are produced when the cable burns), special The wires and cables used to transmit electric energy and communication signals are not only required to have flame retardant properties such as preventing the flame from spreading when the cable and the surrounding en...
