Problems solved by technology

At present, the kayaks or rubber boats used for rafting are generally made of airtight waterproof cloth. This kind of airtight waterproof cloth generally adopts the process of adding a layer of PVC coating film on the polyester woven fabric. Due to different polyester The dry heat shrinkage and tensile strength of woven fabrics are different. Under long-term continuous pressure, the wicking effect will become more and more obvious. As the PVC coating ages, the wicking effect will destroy the peel strength and make the product surface Cracks and delamination occur, and the product life is greatly shortened

Embodiment 1

[0053] Since the products are mainly used in the field of inflatable equipment, the requirements for various indicators of the products are extremely high, especially the durability, air tightness and impact resistance of outdoor products. The performance strength of a product is mainly determined by raw materials and formulations, so selecting appropriate raw materials and additives is an important link.

[0054] Base fabric: 1000D woven fabric is selected as the waterproof fabric base fabric, and the density of the woven fabric is 20 strands / cm×20 strands / cm;

[0055] Process flow:

[0056] 1. Anti-wicking treatment process: base fabric unwinding → anti-wicking treatment → drying → cooling → coiling

[0057] 2. Scratch coating processing technology: base cloth unwinding → slurry preparation → scraping coating → drying and plasticizing → cooling → coiling;

[0058] 3. Laminating process of PVC film and base fabric: base fabric unwinding→heating→pressing→cooling→coiling-insp...

Embodiment 2

[0092] 1. Specific steps of base fabric anti-wicking treatment process:

[0093] 1) Unwind the base fabric by the unwinding device;

[0094] 2) Enter the impregnation tank at a speed of 15m / min for padding. The solution in the impregnation tank is composed of deionized water and anti-wicking agent. The volume ratio of ionized water and anti-wicking agent is 100:10. The composition of anti-wicking agent is a C6 perfluoroacrylate;

[0095] 3) enter the oven for finalizing;

[0096] 4) Enter the cooling device for cooling.

[0097] Second, the specific steps of the base cloth coating process:

[0098] 1) Unwind the base fabric after anti-wicking treatment by the unwinding device;

[0099] 2) After preparing the slurry, perform knife coating treatment.

[0100] 3) The knife-scratch coating adopts multiple scraping processes to make the surface of the product more smooth and air-tight.

[0101] The first coating (one coating) base cloth coating formula is as follows (parts by...

[0123] 1. Specific steps of base fabric anti-wicking treatment process:

[0124] 1) Unwind the base fabric by the unwinding device;

[0125] 2) Enter the impregnation tank for padding at a speed of 15m / min. The solution in the impregnation tank is composed of deionized water and anti-wicking agent. The volume ratio of ionized water and anti-wicking agent is 100:10. The composition of anti-wicking agent is a C6 perfluoroacrylate;

[0126] 3) enter the oven for finalizing;

[0127] 4) Enter the cooling device for cooling.

[0128] Second, the specific steps of the base cloth coating process:

[0129] 1) Unwind the base fabric after anti-wicking treatment by the unwinding device;

[0130] 2) After preparing the slurry, perform knife coating treatment.

[0131] 3) The knife-scratch coating adopts multiple scraping processes to make the surface of the product more smooth and air-tight.

[0132] The first coating (one coating) base cloth coating formula is as follows (parts by...

Abstract

The invention relates to a technology for producing anti-wicking airtight waterproof cloth, which is characterized by comprising the following steps: performing anti-wicking processing on a base cloth, processing a knife-scraping coating, and applying a PVC membrane and the base cloth. The technology comprises the following steps: 1)unreeling the base cloth by an unreeling apparatus; 2) padding in a soaking trough, wherein a solution in the soaking trough is composed of deionized water and an anti-wicking agent, volume ratio of deionized water to the anti-wicking agent is 100: 9-13, the component of the anti-wicking agent is perfluoroalkyl acrylate; 3)fixing in a baking oven; and 4)cooling in a cooling device. By preferably selecting the base cloth raw material, the anti-wicking treatment is carried out, the membrane and the coating base cloth are processed through applying, the anti-wicking airtight waterproof cloth has anti-wicking and excellent air tightness, wicking effect due to the fabric aperture characteristic and fabric structure can be effectively reduced, and the problems of cracks and mildew of the material due to intrusion of extraneous moisture through the wicking effect can be solved.

Description

technical field [0001] The invention relates to a waterproof cloth, in particular to a production process for an anti-wicking airtight waterproof cloth applied in the field of inflatable equipment. Background technique [0002] Rafting in China is also on the rise, and kayaking competitions and rubber boat tourism have been launched in many famous rivers in China. At present, the kayaks or rubber boats used for rafting are generally made of airtight waterproof cloth. This kind of airtight waterproof cloth generally adopts the process of adding a layer of PVC coating film on the polyester woven fabric. Due to different polyester The dry heat shrinkage and tensile strength of woven fabrics are different. Under long-term continuous pressure, the wicking effect will become more and more obvious. As the PVC coating ages, the wicking effect will destroy the peel strength and make the product surface Cracks and delamination occur, and the product life is greatly shortened. Conte...
