Low-smoke bittern-free flame-retardant polyolefin material and braided fabric manufactured thereby

Abstract

The invention relates to low smoke non-halogen flame-resistant polyolefine material and compound weaved cloth made of the low smoke non-halogen flame-resistant polyolefine material. The low smoke non-halogen flame-resistant polyolefine material is composed of polyolefine resin and inorganic flame retardant. The manufacturing process of the weaved cloth comprises the following steps: on one hand, polyolefine material is taken to be filled into a plastic extrusion molding machine, film is extruded through the plastic extrusion molding machine, and then cooled and cut, heated and directionally stretched, the pre-heating treatment is performed to the film to be shaped, and then the film is rolled, and woven in across warp and warp direction into plastic cloth; on the other hand, the low smoke non-halogen being flame-resistant polyolefine material is taken to be filled into a clothes rack type flat frame head plastic extrusion molding machine, and film coating is extruded through the clothes rack type flat frame head plastic extrusion molding machine; after two aspects are accomplished, the film coating is hot melt and continuously compressed into the low smoke non-halogen flame-resistant polyolefine weaved cloth through a compound rolling drum. The technology of the invention can improve the low smoke non-halogen flame-resistant performance and the anti-aging performance of the polyolefine plastic weaved cloth.

Description

technical field [0001] The invention relates to a polyolefin plastic woven cloth, especially a low-smoke, halogen-free flame-retardant polyolefin material and a composite woven cloth made of the material. Background technique [0002] Plastic weaving products are an important part of plastic products. According to the statistics of "Plastic Knitting Packaging", the plastic knitting industry completed an output value of about 53 billion yuan in 2007; Higher profits require the development of new products in order to obtain innovative technical plastic woven series products with high economic growth points, such as: new functional plastic woven materials with low-smoke, halogen-free, flame-retardant, anti-static, etc.; traditional polyolefin Plastic woven polymer is a flammable and combustible material. When burning, it has a large heat release rate, high calorific value, fast flame propagation speed, not easy to self-extinguish, and strong flame retardancy. It will also produ...

[0002] Plastic weaving products are an important part of plastic products. According to the statistics of "Plastic Knitting Packaging", the plastic knitting industry completed an output value of about 53 billion yuan in 2007; Higher profits require the development of new products in order to obtain innovative technical plastic woven series products with high economic growth points, such as: new functional plastic woven materials with low-smoke, halogen-free, flame-retardant, anti-static, etc.; traditional polyolefin Plastic woven polymer is a flammable and combustible material. When burning, it has a large heat release rate, high calorific value, fast flame propagation speed, not easy to self-extinguish, and strong flame retardancy. It will also produce thick smoke or poisonous and harmful when burning. , corrosive gas, causing secondary disasters, harming the environment and posing a huge threat to human life safety; this kind of woven fabric is easy to burn when it encounters fire, and its strength is not good, so the scope of use is limited
