Preparation process of anti-static polyvinyl chloride (PVC) homogeneous through-core coiled material floor board

Abstract

The invention relates to a preparation process of an anti-static polyvinyl chloride (PVC) homogeneous through-core coiled material floor board. The preparation process includes the following steps: PVC particles are prepared through a PVC granulating process; conductive slurry is wrapped on the surfaces of the PVC particles and dried, and a layer of conductive thin film is respectively formed on the surfaces of the PVC particles; or electric conductors are evenly mixed in the PVC particles; the PVC particles wrapped by the conductive thin film or the PVC particles mixed with the electric conductors are put into a drum-type vulcanizer to be molded through vulcanization; and aftertreatment is processed. The preparation process of the anti-static PVC homogeneous through-core coiled material floor board has the advantages of being simple in manufacturing process, good in stability, long in service life of the manufactured floor board, even in conductivity performance, small in joint during pavement, clear and natural in pattern and strong in third dimension. The dimension of the manufactured floor board can be 2.0m*50m generally or can be longer.

Description

technical field [0001] The invention relates to the technical field of preparation of PVC homogeneous core-permeable floor, in particular to a preparation process of antistatic PVC homogeneous core-permeable coil floor. Background technique [0002] At present, in many public places with a large flow of people, such as hospitals, airports, subways, large shopping malls, and libraries, PVC rolls are mostly used as the material for laying the ground, because this material has moderate hardness, resilience, and sound insulation. , Non-slip, moisture-proof, warm effect. However, in the manufacturing workshops of electronic components and electronic equipment, computer rooms, etc., PVC coils are required to have the function of preventing static electricity. [0003] In the prior art, the antistatic PVC floor currently used has the following types: [0004] (1) Add carbon black conductive particles to the PVC raw material and heat the laminated PVC coil. This anti-static PVC co...

Problems solved by technology

This method is currently the most popular anti-static PVC material on the market. It is a permanent anti-static product with uniform conductivity and beautiful appearance, but its size is small, generally between 600×600~900×900. The construction is troublesome and there are many seams, and the quality inspection of the laying is difficult to guarantee.

[0006] (3) Anti-static PVC coil made by splicing method. This anti-static PVC coil is firstly made of PVC into anti-static block. After grinding and polishing, the anti-static PVC block is spliced ​​into PVC by splicing machine. Then, on the continuous plate hot press or drum hot press, the finishing process of heating and rolling the spliced ​​PVC coils is carried out. The antistatic PVC coils made by this splicing method have uniform conductivity and small size. It can reach 2.0m x 50m, and it can be larger, which reduces the trouble of construction, but this kind of manufacturing process is complicated, and the strength of the splicing is not good, the thickness of the splicing is difficult to control, and the appearance is not beautiful
