Embodiment 1～4

[0029] refer to figure 1 , a non-curling flexible composite material, prepared by the following method:

[0030] (1) High-strength polyester yarn is used as warp yarn, nylon monofilament is used as weft yarn, and woven fabric is made by Sulzer projectile loom plain weaving process as the skeleton material;

[0031] (2) After the skeleton material in step (1) is dipped and preformed, the double-sided PVC film is hot-melt bonded, and then subjected to rapid cooling and surface treatment to obtain a flexible composite material without curling.

[0032] The specification of the high-strength polyester filament is 500d, and the specification of the nylon monofilament is Φ0.25mm.

[0033] The PVC film is produced by the following method: the PVC ingredients are cooled and stirred at a high speed, then planetary extruded to achieve full plasticization in the early stage, and then plasticized again by two-roller refining and then four-roller calendering process to make PVC film.

[0042] Change the composition of PVC batching, other preparation technology is the same as embodiment 1. The properties of PVC ingredients and the prepared flexible composite material are shown in Table 2:

[0043] Table 2

[0044]

[0045] The results show that adding the mixture of modified light calcium carbonate and nano-calcium carbonate as a filler, the surface wetting tension of the obtained flexible composite material is the largest, that is, the ink absorption is the best, and the strength is also improved. This is because the modified calcium carbonate can be fully integrated with the organic system, and has good dispersion and compatibility. And because the nano-calcium carbonate is filled in the organic polymer, the interface between the high-modulus calcium carbonate and the low-modulus organic polymer can undergo appropriate stress transfer, making the interface plastic and preventing the interface between the powder and the substrate. Cracks occur due to pe...

[0047] The flexible composite material prepared in Example 4 of the present invention is compared with the conventional flexible composite material, and the results are shown in Table 3 below:

[0048] table 3

[0049] Conventional Flexible Composite Materials

[0050] The results show that compared with the conventional flexible composite material, the flexible composite material of the present invention has the advantages of good ink absorption, no curling, high strength, good aging resistance and the like.

Abstract

The invention relates to a non-curling flexible composite material, which is prepared by the following method: (1) high tenacity polyester filament is adopted as warp, nylon monofilament is adopted as weft, woven fabrics manufactured by a plain weaving process of a Sulzer gripper loom are adopted as framework materials; and (2) after the framework materials in the step (1) are processed by gum dipping and pre-setting, a double-sided PVC film is adopted for hot melting and jointing, and after cooling and surface treatment, the non-curling flexible composite material is prepared. The flexible composite material prepared by the invention has excellent non-curling performance, and simultaneously has the characteristics of high ink absorption, high strength, aging resistance and the like.

Description

(1) Technical field [0001] The invention relates to the field of textile materials, in particular to a flexible composite material used as an inkjet advertising cloth. (2) Background technology [0002] With the progress of the society and people's in-depth understanding and understanding of the advertising industry, the domestic advertising industry has developed rapidly. At the same time, due to the rapid development of the color inkjet technology in the printing field of the IT industry, it also objectively promotes the rapid development of outdoor advertising. Among them, the outdoor advertising industry has been favored by more and more advertising business owners due to its strong visual impact and competitive cost. The common form of advertising is light box advertising. Nowadays, whether you are running on the highway or walking in the streets and alleys of the city, you can see all kinds of colorful light box advertisements everywhere. The coloring method often us...
