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

[0020] A preparation method for a PVC granule permeable coil floor, the method comprising the following process steps:

[0021] (1) PVC 50Kg, DINP 16Kg, CaCO 3 50Kg, heat stabilizer Ca / Zn 1Kg, Ba / Zn 2Kg, modifier ACR-403 1Kg, 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.

[0022] (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.

[0023] (3) Calendering: Put the blue and dark blue PVC particles into the mixer in a ratio of 1:1 and mix them evenly, and then enter the high-power single-screw extruder (L / D=28) to mix ...

Embodiment 2

[0028] A preparation method for a PVC granule permeable coil floor, the method comprising the following process steps:

[0029] A method for manufacturing a PVC granule permeable coil floor, characterized in that the method comprises 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-401 4kg , 8 kg of titanium dioxide, put 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, again Turn to low speed (300-500 rpm) and stir for 2-3 minutes. The mixed materials are discharged into the low-speed cold stirring pot, dispersed and cooled to 25°C, then discharged into the storage tank, and then sent into the twin-screw by the screw conveyor. The extruder is fully heated (the body temperature of the single-screw extruder is 130-...

Embodiment 3

[0036] A preparation method for a PVC granule permeable coil floor, the method comprising the following process steps:

[0037](1) PVC granulation: PVC 100kg, DINP 35kg, calcium carbonate 100kg, Ca / Zn composite heat stabilizer 3kg, Ba / Zn composite heat stabilizer 3kg, modifier ACR-401 1kg, modifier ACR-403 1kg , 2kg of heat-resistant purple red, 2kg of carbon black, 2kg of organic perylene red, 2kg of permanent yellow, and 2kg of phthalocyanine green are put into the mixer and stirred at low speed (300-800 rpm) for 2-3 minutes, and then transferred to high-speed (1000 rpm) ~1200 rpm) and stir for 5-6 minutes, the temperature rises to 95°C, then turn to low speed (300-500 rpm) and stir for 2-3 minutes, the mixed materials are discharged into the low-speed cold stirring pot, dispersed and cooled to 20 ℃, and then discharged into the storage tank, and then sent to the twin-screw extruder by the screw conveyor for full heating (the body temperature of the single-screw extruder is ...

Abstract

The invention relates to a PVC granular 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 invention organically combines PVC granulating method and PVC calendering method. 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 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. Sp...
