Problems solved by technology

[0003] 1. Existing composite method PVC floor coil: film printing multi-layer PVC thermal composite production method, general wear resistance, easy to wear through the pattern, poor composite layer, weak welding and other defects, not suitable for public areas with large traffic place use
[0004] 2. Existing coating and scraping method for PVC floor coils: the production method of coating and scraping PVC paste on the base material and entering the oven for plasticization has no defects such as poor thermal shear strength, easy wear of the pattern, poor wear resistance, and the surface is not stain-resistant. Only suitable for places with low traffic, such as families

Embodiment 1

[0021] A preparation method for a PVC granule semi-permeable coil floor, the method comprising the following process steps:

[0022] (1) PVC 50Kg, DINP 16Kg, CaCO 3 50Kg, heat stabilizer Ca / Zn 1Kg, Ba / Zn 2Kg, modifier ACR-4031Kg, titanium dioxide 4Kg, original blue 0.02, heat-resistant purple red 0.009, etc., add to the high-speed mixer and stir. Temperature to 95°C discharge to cold stirred pot. Other color pigments are different.

[0023] (2) The screw conveyor feeds the material into the twin-screw extruder to fully heat, shear and plasticize. Then enter the single-screw extruder for further heating (body 140°C, head 172°C), plasticize, and the exit rotary knife cuts and granulates (Φ8mm). Finally, the finished blue PVC granules are cooled by two-stage cyclone. Screen through a vibrating sieve, weigh and bag for later use.

[0024] (3) Calendering molding: put PVC particles of blue, dark blue, white and black in a ratio of 1:1:0.5:0.2 into the mixer and mix evenly, and ...

Embodiment 2

[0029] A method for manufacturing a PVC granule semi-permeable coil floor, the method comprising the following steps:

[0030] (1) PVC granulation: Polyvinyl chloride resin (PVC) 100kg, diisononyl phthalate (DINP) 30kg, calcium carbonate 100kg, Ca / Zn composite heat stabilizer 4kg, modifier ACR-4014kg, Put 8kg of titanium dioxide into the mixer at low speed (300-800 rpm) and stir for 2-3 minutes, then turn to high-speed (1000-1200 rpm) and stir for 5-6 minutes, the temperature rises to 110°C, and turn again Stir at a low speed (300-500 rpm) for 2-3 minutes, discharge the mixed material into a low-speed cold stirring pot, disperse and cool to 25°C, then discharge it into a storage tank, and then send it into a twin-screw extruder by a screw conveyor. Exit the machine to be fully heated (the body temperature of the single-screw extruder is 130-145°C, and the head temperature is 170-175°C), cut, plasticized, and then enter the single-screw extruder for further heating, plasticized...

Abstract

The invention relates to a PVC granular semi-permeable coiled floor, and its preparation method. The floor material comprises (by weight parts) polyvinyl chloride (PVC) resin 100, diisononyl phthalate 30-35, calcium carbonate 100, thermal stabilizer 4-6, modifier 2-4, and color masterbatch 8-10. The floor is prepared by PVC granulating, calendering, heating and plasticating, calendering, and post-treatment. The product has high density and wear resistance, clear pattern, wide applicability, and environmental friendliness. The leftovers and unqualified products can be recycled. The floor has high self quality value and social value.

Description

technical field [0001] The invention relates to a plastic floor, in particular to a PVC particle semi-permeable coiled floor and a manufacturing method thereof. Background technique [0002] With the development of my country's economy, the improvement of people's lives, and the continuous improvement and beautification of public facilities, it is used as flooring materials in public places such as airports, subways, hospitals, schools, kindergartens, nursing homes, shopping malls, office buildings, etc. (especially PVC paving) ground materials) demand has grown by leaps and bounds. It mainly comes from foreign brand products and low-end products produced by a few domestic manufacturers. Most of the products currently on the market are composite PVC floor coils and coating and scraping PVC floor coils, which have defects in functionality and usability to varying degrees. Mainly manifested in poor wear resistance, poor stain resistance, poor strength, short service life, etc...
