Abstract

The invention relates to the technical field of polymer materials, in particular to a polyester mesh false roof and a preparation method thereof. The false roof of halogen-free flame-retardant and antistatic polyester mesh used in underground coal mines includes a vertical and horizontal grid-shaped false roof main body made of roof belts. The roof belt is made of halogen-free flame-retardant polyester industrial filament warp weaving machine. The polyethylene terephthalate used in the top belt of the present invention includes a phosphorus-based reactive flame retardant and an antistatic agent component, which has flame-retardant and antistatic properties; it overcomes the polyester fiber used in coal mines in the prior art Reinforced plastic mesh false roof has the defect of complex production process; compared with the prior art polyester fiber reinforced plastic mesh false roof for underground coal mines, the halogen-free flame retardant and antistatic polyester mesh false roof has smaller volume, compact structure, and lower weight. At least 50% lighter; and halogen-free, less toxic after burning.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyester mesh false top and a preparation method thereof. Background technique [0002] When using false roofs in coal mines to mine thick coal seams in layers, when the first layer is taken, materials such as bamboo fence and metal mesh are laid on the roof, and then the pillars are put on the roof, and the collapsed rock is compacted to form the next layer. The roof during mining; it is a safety product used in underground coal mines. [0003] At present, the roadway support materials used in underground coal mines mainly include metal wire mesh false roofs, plastic mesh false roofs for underground coal mines, steel-plastic composite mesh false roofs for underground coal mines, two-way stretch plastic mesh false roofs for underground coal mines, and polyester for underground coal mines. Fiber reinforced plastic mesh false top. [0004] Due to the shortcomings of heavy wei...
