Paste resin and composite cloth for composite cloth

Abstract

The invention relates to a paste resin for a composite cloth and the composite cloth. The composite cloth is prepared through the steps of by taking a gridding cloth as a framework material, carrying out paste resin dipping and drying presetting treatments, and then pasting PVC (Poly Vinyl Chloride) films on the two sides of the framework material by virtue of hot melting, thereby obtaining the composite cloth by virtue of knurling, cooling, setting and edge cutting, wherein the paste resin is composed of the following components in parts by weight: 100 parts of PVC paste resin, 110-130 parts of plasticizer, 1-3 parts of stabilizer, 25-40 parts of environment-friendly solvent oil, 25-35 parts of ethyl ester diluent, 15-25 parts of adhesive and 10-35 parts of benzoic acid inhibitor. The paste resin is capable of effectively retarding agglomeration and solidification of a slurry, so that the slurry can be exposed under an open condition for certain time, the solidification of the slurry in the dipping process is avoided, and excellent dipping effect is guaranteed; meanwhile, the obtained composite cloth has excellent tensile strength, tear strength and peel strength, and also has the characteristics of good flexibility, high damage endurance, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of advertising, and in particular relates to a paste resin used for a composite cloth and a composite cloth. Background technique [0002] With the progress of society and people's in-depth understanding and understanding of the advertising industry, the domestic advertising industry has developed rapidly, and the outdoor advertising industry has been favored by the majority of advertising industry due to its strong visual impact and competitive cost. favor. With the rapid development of the IT industry, in the field of printing, the colors and lines are more refined, the format is more flexible, the picture is more colorful and the price is more acceptable to people. The development of color inkjet technology meets the needs of outdoor advertising producers and promotes the accelerated development of outdoor advertising. The revenue of the domestic outdoor advertising industry is increasing at an annual ra...

Problems solved by technology

Gluing not only increases the production cost, but also easily causes uneven coating, which will directly affect the spray-painted pattern and affect the visual effect. Due to the poor compatibility between the middle grid cloth and the PVC mask / bottom film, its physical strength ( Tear strength and peel strength) are poor, the base fabric is easy to harden, poor flexibility, easy to break, and short service life

[0005] In the prior art, there is also a method of impregnating (soaking slurry) on the base cloth, but the slurry generally used for coating is easy to solidify due to the short opening time (that is, the solidification time of slurry agglomeration), and is not suitable for dipping. Slurry method, the slurry method is generally used for polyurethane glue, but the impregnation of polyurethane glue will have a certain impact on the tear strength of the product, and it is easy to harden the base fabric, thereby affecting its softness and making the product easy. damage, affecting service life
