Problems solved by technology

Mainly manifested in poor wear resistance, poor strength, short service life, etc.
[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

[0024] Such as figure 2 Shown, the preparation method of black titanium crystal sprinkled PVC coil floor, the method comprises the following process steps:

[0025] (1) PVC 100Kg, DINP 30Kg, CaCO 3 100Kg, heat stabilizer Ca / Zn 2Kg, Ba / Zn 2Kg, modifier ACR-403 3Kg, titanium dioxide 1Kg, original blue 1Kg, heat-resistant purple 2Kg, put into the mixer and stir at a low speed, the speed of the middle and low speed stirring is 100 ~250 rpm, continue to high-speed stirring for about 6 minutes, the speed of high-speed stirring is 1000-1200 rpm, the temperature rises to 100°C, turn to low speed again, and the mixed materials are discharged into a low-speed cold stirring pot for dispersion Cooling, the speed of stirring at low speed is 100~250 rpm. Then it is discharged into the storage tank, and then sent to the twin-screw extruder by the screw conveyor to fully heat, shear and plasticize. Then enter the single-screw extruder for further heating (the body temperature of the sing...

Embodiment 2

[0032] A method for manufacturing a black titanium crystal sprinkled PVC coil floor, characterized in that the method comprises the following steps:

[0033] (1) PVC granulation: Polyvinyl chloride resin (PVC) 100kg, diisononyl phthalate (DINP) 35kg, calcium carbonate 100kg, Ca / Zn composite heat stabilizer 6kg, modifier ACR-401 4kg , titanium dioxide 2kg, put into the mixer at a low speed (300-800 rpm) and stir for 2-3 minutes, then transfer to a 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 130-145°C, and the head temperature is 170-175°C), shearing, plasticizing, and then entering the single-scr...

Embodiment 3

[0039] The preparation method of black titanium crystal sprinkled PVC coil floor, the method comprises the following process steps:

[0040] (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 , 0.5kg of heat-resistant purple red, 0.5kg of carbon black, 2kg of organic perylene red, 1kg of permanent yellow, and 1kg of phthalocyanine green, put into the mixer and stir at low speed (300-800 rpm) for 2-3 minutes, and then turn to high speed (1000-1200 rpm) stirring for 5-6 minutes, the temperature rises to 95°C, then turn to low speed (300-500 rpm) and stir for 2-3 minutes, and the mixed materials are discharged into a low-speed cold stirring pot for dispersion and cooling to 20°C, 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 i...

Abstract

The invention relates to a black rutile patterned PVC (polyvinyl chloride) sheet floor and a manufacturing method thereof. The floor comprises a backing layer and a PVC particle layer, a black rutile patterned layer and a UV (ultraviolet) processing layer which are sequentially arranged on the backing layer. As the PVC granulation process, the PVC rolling process and the PVC patterning process are combined organically, the floor manufactured by the method has higher density and wear resistance, cleaner and more natural patterns and wider adaptability and is more environment-friendly in application as compared with products manufactured by other processes and methods.

Description

technical field [0001] The invention relates to a plastic floor, in particular to a black titanium crystal sprinkled PVC 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, the demand for flooring materials (especially PVC flooring materials) in public places such as airports, subways, hospitals, shopping malls, and office buildings has skyrocketed. Long. 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 strength, short service life and so on. [0003] 1. Existing composite method PVC floor coil: film printing...
