Embodiment Construction

[0018] A waterproof, fireproof, flame retardant, low-smoke and halogen-free composite material, including the following weight ratio raw materials: polyethylene resin (PE) 70-80; dioctyl phthalate (DOP) or triisooctyl trimellitate (TOTM ) 10-20; Ca-Zn stabilizer 2-5; n-butyl ester or PE wax 2-3; aluminum hydroxide 5-10; PE extrusion foaming agent (TA860) 1-2; hydrophobic agent 2-3; Triazine char-forming agent 10-20; elastomer (TPE) 1-3; Nali synthetic agent 10-20.

[0019] In this embodiment, it can be properly adjusted within the range of the above-mentioned weight ratio according to different products or functional structural layers such as the outer sheath layer of cables and wires, floors, wall panels, ceilings and fire shutters.

[0020] In this embodiment, the lubricant uses PE wax or n-butyl ester, commercially available raw materials; the flame retardant uses aluminum hydroxide, which is an inorganic flame-retardant article in halogen-free, and is suitable for compound...

Abstract

The invention relates to a low smoke zero halogen composite material with functions of water resistance, fire protection and flame retardance. The material comprises the following raw materials in percentage by weight: 70-80 polyethylene (PE) resin, 10-20 plasticizer, 2-5 stabilizing agent, 2-3 lubricant, 5-10 flame retardant, 1-2 PE (Polyethylene) foaming agent, 2-3 hydrophobing agent, 10-20 carbonizing agent, 1-3 elastomer (TPE) and 10-20 PE synthesizing agent. The composite material can be produced to corresponding products or functional structure layers of the products through the extrusion moulding, and is mainly applied in the products or the functional structure layers, such as outer sheath layers of electric cables and electric wires, floors, wall plates, ceilings, fire resisting shutters and the like. The composite material has the advantages of excellent water resistance, fire protection, heat insulation, smoke prevention, ageing resistance, corrosion resistance and the like.

Description

technical field [0001] The invention relates to a low-smoke and halogen-free composite material with waterproof, fireproof and flame-retardant functions, which can be applied to the outer sheath layer of cables and wires, floors, wall panels, ceilings and fireproof roller shutters in building construction. Background technique [0002] There are many existing waterproof or fireproof materials, but their performances are relatively single, there is no comprehensive technical functional material, and their uses are single. In modern buildings, several different functional materials need to be used to meet the requirements of waterproof, fire prevention, and corrosion resistance, which consume a lot of manpower, material resources and financial resources. Contents of the invention [0003] The purpose of the present invention is to address the above existing problems and provide a low-smoke and halogen-free composite material with strong comprehensiveness, wide applicability,...
