Problems solved by technology

However, due to the special wire drawing structure of the space cloth, the coating method of ordinary materials (such as grid cloth and various single-layer base fabrics) cannot be directly applied to the space cloth, although a targeted coating method has been developed for the space cloth. , but the two layers of the existing space cloth are made of polyester PET fiber. For the space cloth made of the newly developed ultra-high molecular weight polyethylene fiber, it is difficult to integrate the PVC film or TPU film with the space cloth. Bonding, and the peel strength is not up to standard after bonding

preparation example Construction

[0018] The present invention provides a kind of preparation method of space cloth material, comprises the following steps:

[0019] Step 1, the upper surface and the lower surface of the PE space cloth are ironed respectively, and the upper surface and the lower surface of the PE space cloth after the ironing process are coated with PU paste at the same time, and then dried to obtain the pasted PE space cloth;

[0020] Wherein, the paste amount of the PU paste is 50-80gsm, and the viscosity of the PU paste is 40000-60000cps;

[0021] Step 2. The pasted PE space cloth and the film are preheated respectively, and then the film is placed on both sides of the pasted PE space cloth, and hot-pressed to obtain the space cloth material;

[0022] The PE space cloth includes an upper base cloth, a lower base cloth and a wire drawing structure arranged between the upper base cloth and the lower base cloth.

[0023] The upper surface of the PE space cloth is the upper bottom surface of t...

Embodiment 1

[0039] A preparation method of a space cloth material, specifically comprising the following steps:

[0040] Step 1. The upper surface and the lower surface of the PE space cloth are respectively ironed at 100°C, and the upper surface and the lower surface of the PE space cloth after the ironing treatment are coated with PU paste at the same time, and then dried at 120°C to obtain Paste PE space cloth;

[0041] Wherein, the amount of paste on one side of the PU paste is 60gsm, and the viscosity of the PU paste is 40000cps;

[0042] Step 2. Preheat the pasted PE space cloth and the TPU film respectively, and then place the TPU film on both sides of the pasted PE space cloth at 40kg / cm 2 , 150°C for hot-press lamination to obtain the space cloth material;

[0043] Among them, the preheating temperature of the upper surface and the lower surface of the PE space cloth is 100°C, and the preheating temperature of the TPU film is 120°C.

Embodiment 2

[0045] A space cloth material, prepared by the following preparation method of the space cloth material, the preparation method of the space cloth material specifically includes the following steps:

[0046] Step 1. The upper surface and the lower surface of the PE space cloth are respectively ironed at 90°C, and the upper surface and the lower surface of the PE space cloth after the ironing treatment are coated with PU paste at the same time, and then dried at 100°C to obtain Paste PE space cloth;

[0047]Wherein, the pasting amount of the PU paste is 50gsm, and the viscosity of the PU paste is 60000cps;

[0048] Step 2. Preheat the pasted PE space cloth and the PVC film respectively, and then place the PVC film on both sides of the pasted PE space cloth at a temperature of 30kg / cm 2 , 170 ° C under hot pressing lamination, to obtain the space cloth material;

[0049] Among them, the preheating temperature of the upper and lower surfaces of the PE space cloth is 105°C, and ...

Abstract

The invention discloses a preparation method of a space cloth material, and belongs to the technical field of composite materials. The preparation method includes the following steps that the upper surface and the lower surface of PE space cloth are ironed correspondingly, PU (polyurethane) paste is simultaneously applied to the upper surface and the lower surface, drying is conducted, films to bepasted and the pasted PE space cloth are simultaneously preheated, the films are pasted to the upper surface and the lower surface correspondingly, and the space cloth material is obtained. Accordingto the preparation method of the space cloth material, the problems that the films and the PE space cloth are hardly pasted, and the peel strength after pasting does not reach the standard are solved, the peel strength after pasting can reach 150 N / 5 cm or above, a product prepared from the obtained space cloth material can bear higher air pressure, the preparation method can be used for pastingof TPU films and can also be used for pasting of PVC films, and only one time of pasting is conducted, so that the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a preparation method of a space cloth material. Background technique [0002] The space fabric is different from the mesh fabric obtained from conventional textiles. The space fabric is a 3D three-dimensional hollow structure. The base fabric adopts 3D weaving technology. According to the different drawing methods in the middle, different shapes of cloth surface effects can be formed, such as wavy pattern, starry pattern, one-line pattern, etc. Space cloth can provide a very stable three-dimensional space structure when used, and has the advantages of stable size, smooth surface, good resilience and high specific strength. Most of the space fabrics are used to prepare floating boards, surfboards, kayaks and other products, which need to provide good airtightness. For the space fabrics required for such products, the surface is coated with a special PVC ai...
