Embodiment 1

[0025] Preparation of titanium dioxide slurry: Take 50kg of DINP and add it into the dispersion tank, then add 60kg of titanium dioxide powder under the condition that the rotation speed of the mixer is 50rmp / min, and stir for 0.5 hours. Grinding is carried out with a three-roll machine, and the grinding time is 2 to 5 hours. When the fineness of the slurry is 5 to 20 μm, the grinding is finished.

[0026] The raw materials used in Experiment 1 were all commercially available.

Embodiment 2

[0028] The configuration of the mixed solvent in the flame-retardant coating: Accurately weigh 50kg of ethyl acetate, 15kg of acetone, 10kg of cyclohexanone, and 25kg of 80# gasoline into a 200L dispersion bucket in sequence. Then set the rotation speed of the mixer to 50rmp / min, and stir for 3 min. Then the 200-mesh filter screen filters the material to obtain a mixed solvent.

[0029] The raw materials used in Experiment 2 were all commercially available.

Embodiment 3

[0031] Flame retardant coating configuration: take 8.0kg of mixed solvent and 20.0kg of plasticizer DINP and add them to a 200L dispersion bucket, and add 37.0kg of polyvinyl chloride paste resin, 10.0kg of PTFE suspension resin, 10.0kg titanium dioxide slurry, then adjust the rotation speed to 1500rmp / min, and disperse for 30 minutes. Then add 5.0kg of calcium carbonate under the condition that the rotating speed of the mixer is 50rmp / min, and after dispersing for 5 minutes, adjust the rotating speed to 1500rmp / min, and disperse for 15 minutes. Then, 2.0kg heat stabilizer, 0.3kg anti-ultraviolet agent, 0.3kg bactericide, 5.0kg flame retardant were added sequentially at a rotating speed of 1500rmp / min, and stirred for 5 minutes. After the addition is complete, stir for 5-15 minutes to obtain a homogeneous mixture. Add an appropriate amount of mixed solvent to adjust the viscosity of the coating to 1000-5000mpa.s, filter and pack to obtain a flame-retardant coating.

Abstract

The present invention discloses a fire retardation coating material, a preparation method and uses thereof. The coating material comprises, by weight, 20-40% of a polyvinyl chloride paste resin, 5-10% of a polytetrafluoroethylene suspension resin, 20-30% of an auxiliary agent part (a plasticizer, a heat stabilizer, an anti-ultraviolet agent, a sterilization agent, and a fire retardation agent), 5.0-10% of titanium dioxide, 3-5% of calcium carbonate, and the balance of a solvent part. According to the present invention, the polyvinyl chloride paste resin, the polytetrafluoroethylene suspension resin, the plasticizer, the heat stabilizer, the anti-ultraviolet agent, the sterilization agent, the fire retardation agent, the titanium dioxide and the calcium carbonate are adopted as the raw materials, and titanium dioxide slurry preparing, mixing, viscosity adjusting and a series of processes are performed to prepare the fire retardation coating material; and the PET textile cloth coated with the coating material of the present invention can be used in the field of PET tarpaulins, and has the good fire retardation effect.

Description

technical field [0001] The flame retardant paint disclosed by the invention is used for coating the surface of PET textile cloth, and the PET textile cloth coated with the flame retardant paint can be used in the field of PET tarpaulin and has good flame retardant effect. Background technique [0002] Coated PET textile cloth is a widely used material, a large part of which is used in the tarpaulin field. This material has good performance in terms of wear resistance and rain resistance, but it has a disadvantage: Since the base fabrics used for tarpaulins are mostly fiber materials, and the coatings are mostly PVC paste resin coatings, the flame retardancy is very poor. This material is used in indoor places such as supermarkets, airports, hotels, stations, etc. If it encounters an open flame, it will have disastrous consequences. Contents of the invention [0003] The object of the present invention is to provide a kind of flame-retardant coating that fundamentally solv...
