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] Such as figure 1 Shown, the preparation method of PVC granule flower permeable coil floor, the method comprises the following process steps:

[0021] (1) PVC 50Kg, DINP 16Kg, CaCO 3 Add 50Kg, heat stabilizer Ca / Zn 1Kg, Ba / Zn 2Kg, modifier ACR-4031Kg, titanium dioxide 3Kg, rose red 0.02Kg, medium chrome yellow 0.016Kg, thick black 0.002kg, etc. into the high-speed mixer and stir. Temperature to 95°C discharge to cold stirred pot. Other color pigments are different.

[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 off the pellets (Φ8mm), and finally the red PVC pellets are cooled by two-stage cyclone, Vibrating sieve screening, weighing and bagging for later use.

[0023] (3) PVC granule crushing: Pour Φ8mm PVC granules into a grinder equipped with a 2-3mm aperture sieve for c...

Embodiment 2

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

[0029] (1) PVC granulation: Polyvinyl chloride resin (PVC) 100Kg, diisononyl phthalate (DINP) 30-35Kg, calcium carbonate 100Kg, Ca / Zn composite heat stabilizer 4Kg, modifier ACR- 403 2Kg, modifier ACR-401 2Kg, titanium dioxide 2Kg, original blue 1Kg, heat-resistant purple 1Kg, thick black 1Kg, rose red 1Kg, medium chrome yellow 1Kg, phthalocyanine green 1Kg, phthalocyanine blue 2Kg, put into the mixer Stir at low speed (300 rpm) for 2 to 3 minutes, then turn to high speed (1000 rpm) and stir for 5 to 6 minutes, then turn to low speed and stir for 2 to 3 minutes when the temperature rises to 110°C. Discharge into the low-speed cold stirring pot, disperse and cool to 20-25°C, then discharge into the storage tank, and then send to the twin-screw extruder by the screw conveyor to fully heat, shear, plasticize, and then enter the single-screw extruder (The t...

Embodiment 3

[0035] A method for manufacturing a PVC granule sprinkled permeable coil floor, the method comprising the following steps:

[0036](1) PVC granulation: polyvinyl chloride resin (PVC) 100Kg, diisononyl phthalate (DINP) 30-35Kg, calcium carbonate 100Kg, Ca / Zn composite heat stabilizer 6Kg, modifier ACR- 403 1Kg, modifier ACR-401 1Kg, titanium dioxide 2Kg, medium chrome yellow 2Kg, phthalocyanine green 2Kg, phthalocyanine blue 2Kg, put into the mixer and stir at low speed (800 rpm) for 2 to 3 minutes, then transfer to Stir at high speed (1200 rpm) for 5-6 minutes, the temperature rises to 95°C, then turn to low-speed stirring for 2-3 minutes again, put the mixed material into a low-speed cold stirring pot, disperse and cool to 20-25°C, and then discharge it into In the storage tank, it is sent to the twin-screw extruder by the screw conveyor to fully heat, shear, and plasticize, and then enter the single-screw extruder (the temperature of the body is 130-145°C, and the temperatur...

Abstract

The invention relates to a PVC granule-spread 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, PVC granule crushing, PVC granule spreading, three-roller calendering, and post-treatment. The product has high density and wear resistance, clear pattern, wide applicability, and environmental friendliness. The floor has high plastification, uniform material, high permeability, and stable size stability.

Description

technical field [0001] The invention relates to a plastic floor, in particular to a PVC granule sprinkled transparent 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 lif...
