Description

Coating process for preparing superfine polymer yarn
Technical Field
The invention relates to a coating process for preparing superfine polymer yarns.
Background
At present, PVC cloth or cloth with a PVC coating is mostly adopted as the sun-shading material. The PVC cloth has the following disadvantages: 1) the weather resistance is poor, the material is easy to soften and relax in hot days, and the material is easy to harden and become brittle in cold days; 2) the PVC cloth is easy to age and short in service life; 3) PVC cloth gas permeability is poor, is not suitable for using under the environment that needs ventilation. 4) The weight of the cloth is high, and the application field is limited.
The cloth with the PVC coating is improved in performance compared with PVC cloth, but has the following defects: 1) the PVC coating is easy to fall off and has short service life; 2) PVC cloth gas permeability is poor, is not suitable for using under the environment that needs ventilation. 3) The weight of the cloth is high, and the application field is limited.
In view of the above problems, there is a need to develop a sunshade material with good sunshade, waterproof, air permeability and long service life.
Disclosure of Invention
The invention aims to provide a coating process for preparing superfine polymer yarns, which can be used for preparing superfine polymer yarns and weaving sun-shading materials with sun-shading, light weight, waterproof and air permeability and long service life.
In order to achieve the above purpose, the invention comprises the following steps: step A, coating polyvinyl chloride paste resin slurry on the surface of the yarn; b, heating and shaping the yarn coated with the sizing agent; and step C, cooling the shaped yarn to obtain the superfine polymer yarn.
And a step A1 of passing the yarn coated with the sizing agent through a die with a die hole to remove the excess sizing agent so as to enable the yarn coated with the sizing agent to reach a set diameter is further included between the step A and the step B.
The heating temperature in the step B is 160-180 ℃, and the heating time is 1-5 minutes.
The yarn in the step A is inorganic fiber or organic fiber or a mixture of inorganic fiber and organic fiber.
The inorganic fiber is any one or a mixture of at least two of glass fiber, carbon fiber and boron fiber; the organic fiber is one or the mixture of at least two of chinlon, polypropylene fiber, acrylic fiber, spandex, vinylon, viscose fiber and terylene.
The polyvinyl chloride paste resin slurry in the step A comprises the following components in parts by weight: 60-90 parts of PVC paste resin, 10-40 parts of PVC blending resin, 40-60 parts of plasticizer DOTP, 5-15 parts of diluent, 3-5 parts of heat stabilizer, 10-30 parts of flame retardant, 5-10 parts of titanium dioxide, 10-20 parts of filler, 0.5-1 part of anti-ultraviolet agent and 0.5-1 part of antioxidant.
The flame retardant comprises one or a mixture of at least two of decabromodiphenylethane, brominated polystyrene, antimony trioxide, zinc borate, magnesium hydroxide or aluminum hydroxide.
The filler comprises any one or the mixture of at least two of talcum powder, barium sulfate, calcium carbonate, wollastonite, kaolin and mica powder;
the antioxidant comprises any one or mixture of at least two of phenolic antioxidant, amine antioxidant, phosphite antioxidant or thioester antioxidant.
The light stabilizer comprises any one or a mixture of at least two of hindered amine light stabilizer, triazine light stabilizer or organic nickel complex.
The invention has the beneficial effects that: the high-molecular yarn with the PVC coating layer can be produced by the process and used for manufacturing the sun-shading material, has the advantages of sun protection, heat insulation, water resistance, fire resistance, mildew resistance, ageing resistance, ventilation and air permeability, and has better performance than that of the traditional sun-shading material. After the process is adopted, the raw material yarn can be selected with a thin specification, the thickness of the coating layer can be controlled through the die holes, so that the produced high polymer yarn with the PVC coating layer is thin, the woven fabric is light, soft and good in hand feeling, the requirement on the strength of the supporting structure is low when the fabric is used, the installation is more convenient, and the application field is wider.
