Embodiment 1

[0024] As shown in Figure 1 and Figure 4, coating the PU adhesive layer: first unwind the selected base cloth, and carry out hanging knife coating after passing through the cloth storage rack. The consumption of the adhesive material is 0.015kg / m, and the speed It is 30m / min, and it is dried after coating. The oven temperature is 110°C. After leaving the oven, it is cooled by a steel roller with cooling water circulation, and then wound. PU binder formula: 100 kilograms of two-component PU binder resin for PVC, 3 kilograms of dimethylformamide, 3 kilograms of toluene, and 4 kilograms of bridging agent.

[0025] As shown in Figure 2 and Figure 5, PVC calendering film: first measure 100 kg of PVC-III type resin, 70 kg of DOP, 3 kg of dioctyl sebacate, 2 kg of Ba-Cd-Zn mixed stabilizer, CaCO 3 5 kg, appropriate amount of pigment, put into the kneader, stir evenly at a certain temperature, and initially plasticize. The kneading time is 8 minutes, and then banburying is carried ou...

Embodiment 2

[0027] Coating PU adhesive layer: Firstly, unwind the selected base cloth, pass through the cloth storage rack, and then carry out hanging knife coating. The binder consumption is 0.03kg / m, and the vehicle speed is 15m / min. Drying is carried out after coating, and the oven temperature is 150°C. After leaving the oven, it is cooled by steel rollers with cooling water circulation, and then rolled. The formula of the PU adhesive is: 100 kg of two-component PU adhesive resin for PVC, 8 kg of dimethylformamide, 15 kg of toluene, and 12 kg of bridging agent.

[0028] PVC calendering film: First measure 100 kg of PVC-III type resin, 90 kg of DOP, 15 kg of dioctyl sebacate, 4 kg of Ba-Cd-Zn mixed stabilizer, CaCO 3 15 kg, appropriate amount of pigment. Add it into the kneader, stir evenly at a certain temperature, and initially plasticize, and the kneading time is 12 minutes. Then banburying is carried out, and the color paste is added, and the set temperature is 160°C. After ban...

Embodiment 3

[0030] Coating PU adhesive layer: Firstly, unwind the selected base cloth, pass through the cloth storage rack, and then carry out hanging knife coating. The binder consumption is 0.02kg / m, and the vehicle speed is 20m / min. After coating, it is dried, the oven temperature is 130°C, after leaving the oven, it is cooled by a steel roller with cooling water circulation, and then rolled. The formula of the PU adhesive is: 100 kg of two-component PU adhesive resin for PVC, 5 kg of dimethylformamide, 10 kg of toluene, and 8 kg of bridging agent.

[0031] PVC calendering film: First measure 100 kg of PVC-III type resin, 80 kg of DOP, 10 kg of dioctyl sebacate, 3 kg of Ba-Cd-Zn mixed stabilizer, CaCO 3 10 kg, appropriate amount of pigment. Add it into the kneader, stir evenly at a certain temperature, and initially plasticize. The kneading time is 10 minutes, and then carry out banburying. The set temperature is 165°C. After banburying, carry out kneading for further plasticization....

Abstract

The rain coat cloth with polyvinyl chloride is one three-layer structure including base cloth layer, outer PVC film layer and the polyurethane adhesive layer in between. The preparation process includes painting polyurethane adhesive layer on base cloth layer, stoving, cooling, winding and pressing PVC film. The present invention combines the said two kinds of film to ensure high peeling-off strength, excellent low temperature performance and water pressure resistance over 200 KPa to ensure flood and rainstorm resisting requirement. The rain coat cloth of the present invention has the advantages of good rain resisting effect, excellent physical and mechanical performance, light weight, etc. and is especially suitable for making rain coat for soldiers.

Description

Technical field: [0001] The invention relates to a raincoat cloth and a preparation method thereof. Background technique: [0002] Traditional oilcloth raincoats are often glued together, and the rainproof effect is not good. The strength of the film raincoat is too weak, and the rubber raincoat is too bulky, which is difficult to meet the needs of the PLA for flood fighting, emergency rescue, and marching operations. Invention content: [0003] The purpose of the present invention is to provide a special raincoat fabric, PVC-coated raincoat fabric, which has excellent rainproof effect, good physical and mechanical properties and light weight. [0004] Another object of the present invention aims to provide the preparation method of above-mentioned PVC coated raincoat cloth. [0005] The purpose of the present invention is achieved by the following scheme. [0006] The invention has a three-layer structure, the bottom layer is a cloth base, the outermost layer is a polyv...
