Embodiment 1

[0035] 1. Dip coating treatment of base cloth

[0036] Diameter braided fabrics with directional structure adopt polyester silk cloth or vinylon fiber cloth. Dip coating liquid glue adopts polyurethane paste, adding corresponding solvent, and the solid content is 30%. The base fabric has been treated with liquid glue, its traveling speed is 30-40 m / min, and the amount of paste is 100-120 g / m 2 , drying at 150°C;

[0037] 2. Preparation of modified PVC film

[0038] The component formula is: PVC resin (1300 degree of polymerization) 100 (parts by weight, the same below), DINP 30, barium laurate 1.5, active calcium carbonate (particle size less than 100nm) 5, nitrile rubber 3. Stir the mixture for 5-6 minutes, plasticize it in an internal mixer for 4-5 minutes; heat up, start kneading twice at 150-160°C, filter and extrude at 150-160°C; Calendering at 160°C to obtain a modified PVC film. Finally, it is processed by embossing, cooling, trimming, coiling, packaging and other ...

[0042] 1. Dip coating treatment of base cloth

[0043] The radial braid of directional structure adopts polyester fiber cloth or nylon fiber cloth. The liquid glue for dipping is made of PVC paste, and the corresponding solvent is added, and the solid content is 35%. The base fabric has been treated with liquid glue, its traveling speed is 20-30 m / min, and the amount of paste is 150-180 g / m 2 , drying at 160-170°C;

[0044] 2. Preparation of modified PVC film

[0045] The component formula is: 100 parts by weight of PVC resin, 40 parts of DINP, 3 parts of zinc laurate, 10 parts of activated calcium carbonate (particle size less than 100nm), and 8 parts of nitrile rubber. Stir the mixed liquid for 5-6 minutes, and plasticize it in the internal mixer for 3-4 minutes; heat up and heat up at 140-150°C for two times; filter and extrude at 160-170°C; Calendering at 170°C to obtain a modified PVC film. Finally, it is processed by embossing, cooling, trimming, coiling, packaging ...

Embodiment 3

[0049] 1. Dip coating treatment of base cloth

[0050] The radial braid of the directional structure adopts nylon fiber cloth or glass fiber cloth. Dip-coat liquid gum color polyurethane paste, add corresponding solvent, and the solid content is 32%. The base fabric has been treated with liquid glue, its traveling speed is 10-20 m / min, and the amount of paste is 180-200 g / m 2 , drying at 180°C;

[0051] 2. Preparation of modified PVC film

[0052] The component formula is: 100 parts by weight of PVC resin, DINP60, 2.5 parts of barium laurate and zinc laurate, 20 parts of activated calcium carbonate (particle size less than 100nm), and 10 parts of nitrile rubber. Stir the mixed liquid for 5-6 minutes, then banbury and plasticize it in the internal mixer for 6-8 minutes; heat up, start kneading twice at 160-170°C, filter and extrude at 160-170°C; Calendering at 170°C to obtain a modified PVC film. Finally, it is processed by embossing, cooling, trimming, coiling, packaging ...

Abstract

The present invention relates to netted fabric technology, and is especially a kind of high strength wicking-resisting waterproof netted fabric and its preparation process. The netted fabric is prepared with radial braid possessing directional structure as base fabric and through soaking with liquid rubber, stoving and adhering modified PVC films to its two sides. The netted fabric of the present invention has high tensile strength, high breaking strength, high stripping strength, powerful wicking resistance, good waterproof performance and high weather resistance, and may be used widely in making inflated toy, household swimming pool, tent, etc.

Description

technical field [0001] The invention belongs to the technical field of mesh cloth, and in particular relates to a high-strength core-absorption-resistant and waterproof mesh cloth for household swimming pools and inflatable yachts and a preparation method thereof. Background technique [0002] With the continuous development of society, people's living standards continue to improve. People pay more and more attention to the quality of life, and leisure sports equipment is becoming more and more popular as a part of people's life. Among them, family swimming pools and inflatable yachts have become important choices for some people's lives. [0003] At present, the materials used for family swimming pools and inflatable yachts in the international market are as follows. [0004] 1. PVC film. Due to its low strength, high elongation rate, and poor impact resistance, family swimming pools can only be made into children's swimming pools with a diameter of less than 1 meter and...
