A kind of pvc plastic floor renewable mid-sole material production process

Abstract

The invention provides a production technology of a renewable medium backing material of a polyvinyl chloride (PVC) plastic floor. The technology comprises the steps of putting PVC mixed powder and a plasticizer into a mixer, fully mixing, weighing and packaging; mixing the weighed and packaged mixed power with calcium carbonate and other auxiliary agents, and putting the mixture into an internal mixer; setting the heating temperature of the internal mixer, heating and maintaining the pressure; then, carrying out primary open mill and secondary open mill to obtain a product; feeding the product into a calender and carrying out calendering; cooling the product in a cooling machine; cutting the product into pieces by a cutting machine; judging whether the cut product is qualified, if the cut product is qualified, putting in storage and curing for 12 hours at room temperature, and if the cut product is not qualified, feeding the cut product to the internal mixer in the step b again and carrying out internal mixing. The production technology of the renewable medium backing material of the PVC plastic floor is scientific and reasonable in components of the floor, simple and scientific in production technology and high in product quality and production efficiency.

Description

technical field [0001] The invention relates to the technical field of floor production, in particular to a production process for a renewable midsole material for a PVC plastic floor. Background technique [0002] In the prior art, the application of PVC plastic flooring is more and more extensive, but in the prior art, when technicians usually use PVC plastic recycled materials to produce midsole materials, because they do not know the composition of specific materials, knowledge is produced by feeling, so they produce After the material is made into a finished product, the product performance is unstable due to the change of the returned material. Therefore, in the prior art, it is necessary to use relevant testing equipment to detect the component content of each material, and then perform corresponding material testing according to the requirements. The increase or decrease of the product makes the product reach a unified standard, the process is complicated and the sta...

[0002] In the prior art, the application of PVC plastic flooring is more and more extensive, but in the prior art, when technicians usually use PVC plastic recycled materials to produce midsole materials, because they do not know the composition of specific materials, knowledge is produced by feeling, so they produce After the material is made into a finished product, the product performance is unstable due to the change of the returned material. Therefore, in the prior art, it is necessary to use relevant testing equipment to detect the component content of each material, and then perform corresponding material testing according to the requirements. The increase or decrease of the product makes the product reach a unified standard, the process is complicated and the stability is not high, which affects the improvement of product quality and production efficiency, and the production process needs to be improved.
