Embodiment 1

[0028] A matte flame-retardant and cold-resistant tarpaulin. After the tarpaulin is soaked in glue and dried on the base fabric, the base fabric, PVC mask and PVC base film are laminated on both sides, and then finished with fluorine silicon after cooling and shaping. The surface functional treatment is carried out with the agent, and then it is made by drying and coiling process;

[0029] Wherein, the calendering formula of the PVC mask and the PVC bottom film is: 100 parts by weight of PVC resin powder, 3 parts by weight of antimony trioxide, 50 parts by weight of dioctyl phthalate, 3 parts by weight of dioctyl adipate , 3 parts by weight of titanium dioxide, 3 parts by weight of stabilizer, 2 parts by weight of soybean oil, and 20 parts by weight of calcium carbonate.

[0030] The surface of the PVC mask and the PVC bottom film has been matte treated, and the matte surface can greatly improve the sticking phenomenon between the film and the pressure roller; the base fabric ...

Embodiment 2

[0037] With reference to Example 1, change the calendering formula of PVC facial film, PVC base film, the calendering formula of described PVC facial film, PVC base film is: PVC resin powder 100 weight parts, antimony trioxide 4 weight parts, dioctyl phthalate 60 parts by weight of ester, 4 parts by weight of dioctyl adipate, 5 parts by weight of titanium dioxide, 6 parts by weight of stabilizer, 4 parts by weight of soybean oil, and 20 parts by weight of calcium carbonate.

[0038] The flame retardancy of the covering cloth obtained by the present invention meets the requirements of grade B2 of decorative fabrics in GB / T 17591, the tensile load is ≥2450N / 5cm in the warp direction, and ≥1800N / 5cm in the transverse direction, and the tear load is ≥260N in the warp direction, and ≥260N in the transverse direction. 195N, cold resistance performance: placed at -30°C for 2 hours and folded in half without cracks.

Embodiment 3

[0040] The fluorosilicone finishing agent utilizes the internal C=C and Si-H in its molecule to cross-link to form a film under the action of a catalyst, thereby providing low surface energy on the surface of the fiber. The influence of different process parameters on the finishing effect is investigated. The specific steps refer to Example 1 .

[0041] 1. Effect of baking temperature on finishing effect

[0042] Since the process of fluorine-containing silicone oil cross-linking itself to form a film or reacting with the hydroxyl functional group on the fiber is mainly completed during the baking process, the selection of the baking temperature is very important. The fabrics finished with 25g / L fluorosilicone finishing agent were baked at different baking temperatures, and the effects of the baking temperatures on the water repellency, washability, and mechanical strength of the finished fabrics were tested. The results are shown in Table 1. Show:

Abstract

The invention relates to matte flame-retardant cold-resistant covering cloth. The covering cloth is prepared by performing gumming dipping and drying on base cloth, employing a PVC surface membrane and a PVC bottom membrane to bond with two faces of the base cloth, performing cooling fixing, then employing a fluorosilicone finishing agent to perform surface function processing, and then performing drying and reeling. A double-face bonding production technology of plain base cloth and the PVC surface membrane and the PVC bottom membrane is employed, also a flame retardant and a cold-resisting agent are added into the formula of the PVC membrane, so that the flame retardation performance and the cold resistant performance of the product are improved. The covering cloth possess good flame retardation performance, mechanical properties, cold resistance and the like, and also is greatly improved in applicability and added value by coating the covering cloth surface with a layer of the fluorosilicone finishing agent.

Description

technical field [0001] The invention relates to a tarpaulin, in particular to a matte flame-retardant and cold-resistant tarpaulin. Background technique [0002] Tarpaulin is a kind of product widely used by people. It is mainly used in transportation, transportation, oil fields, coal mines, construction, military industry, civil and tourism, etc., and has become an indispensable part of human life. With the rapid development of the national economy, the demand for tarpaulins in the fields of transportation, ports, open storage, exploration and mining, and national defense equipment has been increasing. At the same time, natural disasters such as earthquakes and floods occur frequently, and the improvement of the national emergency support and risk avoidance system has been promoted to a very important position. Strengthening the establishment of urban emergency support and risk avoidance systems requires the development of multifunctional and high-performance canopy materia...
