Embodiment 1
[0026] A method for preparing an environment-friendly silent floor, specifically attaching a new foamed PE cushion to the back of a hard PVC floor, specifically includes the following steps:
[0027] (1) Production of hard PVC floor semi-finished products: Weigh the raw materials in corresponding parts by weight, mix 100 parts of PVC resin, 280 parts of stone powder, 3 parts of stearic acid, 5 parts of internal lubricant, and 5 parts of impact modifier 3. Add 3 parts of coloring agent to the high-speed mixer. After setting the temperature to 110°C, mix and stir evenly at a speed of 250r / min while raising the temperature. After reaching the temperature, start cold mixing at the same time, and put the The raw material is unloaded to the cold mixer and stirred for 12 minutes; the cold-mixed material is unloaded into the storage tank, and fed into the twin-screw extruder, the temperature of the screw area is 195°C, and the temperature of the outlet mold is 185°C; the calendering te...

[0031] A method for preparing an environment-friendly silent floor, specifically attaching a new foamed PE cushion to the back of a hard PVC floor, specifically includes the following steps:
[0032] (1) Production of hard PVC floor semi-finished products: Weigh the raw materials in corresponding parts by weight, mix 110 parts of PVC resin, 350 parts of stone powder, 8 parts of stearic acid, 4 parts of internal lubricant, and 8 parts of impact modifier 1. Add 1 to 4 parts of colorant to the high-speed mixer. After setting the temperature to 110°C, mix and stir evenly at a speed of 300r / min while raising the temperature. The material in the machine is unloaded to the cold mixer and stirred for 13 minutes; the cold-mixed material is unloaded into the storage tank, and fed into the twin-screw extruder, the temperature of the screw area is 200 ° C, the temperature of the outlet mold is 190 ° C; the calendering temperature is 215 ° C , the hard PVC base material is obtained, which ...

Abstract
The invention discloses a preparation method of an environment-friendly mute hard PVC floor. The hard PVC floor does not use a plasticizer, the lowest layer adopts a novel foaming PE cushion layer, after PE is foamed, crosslinked and molded, a pressure-sensitive adhesive is applied to the back surface, and a release film is pasted, in actual production and use, only the release film needs to be torn off, and the release film is pasted to the back surface of a conventional hard PVC floor, so that the environment-friendly mute hard PVC floor is obtained. No hot melt adhesive is used, the gluing procedure is omitted, harmful substances generated when the adhesive is in a molten state are avoided, environmental protection and no pollution are achieved, the working environment of staff is improved, and the environmental protection property of the product is improved; in addition, the production process is effectively accelerated, and efficiency is improved; and equipment such as a feeding machine, a roller coater, a pressing roller and a receiving machine does not need to be used, and 5-6 workers can be saved in each production line, so that the labor, material and equipment costs are reduced. The production process is simplified, the production period is shortened, the whole floor production period can be shortened by 3-5 days, and the time cost is greatly saved. The prepared floor is good in flatness, and the peel strength and the warping of the prepared floor meet relevant national or industrial standards.
Description
technical field [0001] The invention relates to the field of floor preparation, in particular to a preparation method of an environment-friendly silent floor. Background technique [0002] Silent PVC floor is soft, quiet, comfortable and wear-resistant. Its unique sound insulation effect and thermal insulation performance are very suitable for use in bedrooms, meeting rooms, libraries, recording studios and other places. However, the production process of silent PVC flooring products currently on the market is mainly traditional technology, and hot-melt glue is used to paste IXPE or cork on the back of PVC flooring, which has many shortcomings. [0003] On the one hand, hot melt adhesives will produce certain harmful substances in the melting state during the use of solid hot melt adhesives, which will affect the health of operators; on the other hand, the glue application process will also invisibly increase the difficulty of operation in actual production and use. , if it...
