Embodiment Construction

[0027] Such as Figure 1 to Figure 3 Shown, be tarpaulin coating technology involved in the present invention, specifically comprise the steps:

[0028] (a) Prepare coating slurry: disperse polyvinyl chloride solution in liquid plasticizer, swell and plasticize the mixed solution to form plastisol, then add emulsion, stabilizer, filler, colorant, and then stir, It is made into polyvinyl chloride paste resin, and then chemical additives are added to the polyvinyl chloride paste resin. The chemical additives are plasticizers, anti-fungal agents, anti-aging agents, antistatic agents, adhesives, and penetrating agents. , crosslinking agent and softener, etc. The dosage of each chemical additive is as shown in Table 1:

[0029]

[0030]

[0031] Table 1

[0032] The mixture of polyvinyl chloride paste resin and chemical additives is passed into the Z-type kneader through the screw feeding device, and then kneaded in the Z-type kneader, and then the mixture is sent to the c...

Abstract

The invention discloses an awning cloth coating technology. The technology comprises steps as follows: (a), coating slurry is prepared; (b), base cloth is processed; (c), the base cloth is dried; (d), the base cloth is calendered; (e), the coating slurry is transferred; (f), a thin film and the base cloth are overlapped; (g), awning cloth initial fabric is subjected to water-proof finish; (h), the awning cloth initial fabric is detected; (i), the awning cloth is trimmed, and a finished product is obtained. According to the awning cloth coating technology, chemical additives are added to polyvinyl chloride paste resin, so that the performance of the coating slurry is improved, the base cloth can be rapidly coated with the thin film in a base cloth coating process, the coating is even and reliable, the coating time is short, the thickness of the thin film can be controlled, and the thickness and the breadth of the finished product of the awning cloth are effectively controlled; the preparation efficiency of the awning cloth is improved, the awning cloth has waterproof, mould-proof, cold-resistant, anti-aging, anti-static properties and other properties, besides, breaking strength, tearing elongation and tearing strength of the awning cloth are greatly superior to those of traditional awning cloth, the quality of the finished product of the awning cloth is wholly improved, and demands of users are met.

Description

technical field [0001] The invention relates to a tarpaulin coating process. Background technique [0002] Tarpaulin is a kind of thick cotton fabric or hemp fabric. It is named after it was originally used for sails. Generally, plain weave is used, and a small amount of twill weave is used. Both warp and weft yarns are multi-strand. Tarpaulins are usually divided into two categories: coarse tarpaulins and fine tarpaulins: coarse tarpaulins are also called tarpaulins. The fabric is firm and resistant to folding and has good waterproof performance. It is used for covering automobile transportation and open warehouses and setting up tents in the wild; The warp and weft yarns of the fine tarpaulin are used to make labor protection clothing and its supplies. After being dyed, it can also be used as fabrics for shoes, travel bags, backpacks, etc. In addition, there are rubber tarpaulins, shielding tarpaulins for fire protection and radiation protection, and tarpaulins for paper...
