preparation example Construction

[0023] The invention relates to a preparation process of an economical wear-resistant sandwich cloth, comprising the following steps:

[0024] Step 1: Coat the upper and lower surfaces of the base cloth with the first adhesive, plasticize and cool at 160-180°C.

[0025] Step 2: Preheat the base cloth coated with the first adhesive to 160-180°C, and attach the PVC film to the upper and lower surfaces of the base cloth by preheating at 160-180°C. The PVC layer on the lower surface of the base cloth The thickness is twice the thickness of the PVC layer on the upper surface;

[0026] Step 3: After the PVC film is cooled, lower the temperature of the base fabric to 140-155°C, coat the upper surface of the PVC film layer on the base fabric with a second adhesive, and extrude the TPU film at 140-155°C Casting and laminating on the upper surface of the base fabric, after lamination and cooling, an economical wear-resistant sandwich fabric is obtained; the thickness of the PVC layer o...

[0057] A preparation process of an economical wear-resistant sandwich cloth, comprising the following steps:

[0058] Step 1: Coat the upper and lower surfaces of the base cloth with the first adhesive, plasticize and cool at 168°C.

[0059] Step 2: Preheat the base cloth coated with the first adhesive to 180°C, and at 180°C, preheat the PVC film on the upper and lower surfaces of the base cloth. The thickness of the PVC layer on the lower surface of the base cloth is 2 times the thickness of the PVC layer on the upper surface;

[0060] Step 3: After the PVC film is cooled, lower the temperature of the base fabric to 155°C, coat the upper surface of the PVC film layer on the base fabric with a second adhesive, and stick the TPU film by extrusion casting at 155°C On the upper surface of the base cloth, through bonding and cooling, an economical wear-resistant sandwich cloth is obtained; the thickness of the PVC layer on the lower surface of the base cloth is twice the thicknes...

Abstract

The present invention relates to the field of preparation technology of sandwich cloth, in particular to a preparation technology of economical wear-resistant sandwich cloth; the base cloth is preheated to a high temperature of 160-180°C and extruded at a high temperature of 160-180°C. The PVC film is directly bonded to the upper and lower surfaces of the base fabric by casting; the bonding process does not need to add adhesives, and then use adhesives to cooperate with extrusion casting at 140-155°C to make the TPU film more firmly bonded on the upper surface; because the PVC material has the advantages of low cost and easy welding, most of the present invention uses PVC film on the mask layer material, and the uppermost layer of the sandwich cloth is extruded and cast at a specific temperature through an adhesive , The TPU film is firmly bonded to the upper surface of the sandwich cloth, so that the surface of the prepared sandwich cloth has high wear resistance, and plays a protective role for the whole sandwich cloth.

Description

technical field [0001] The invention relates to the field of preparation technology of sandwich cloth, in particular to a preparation technology of economical wear-resistant sandwich cloth. Background technique [0002] Sandwich cloth is a kind of material with textile mesh cloth as the base material, and one or more layers of different physical properties are compounded on both sides of the mesh cloth. [0003] The Chinese patent application publication number CN10700970A discloses a high-performance anti-ultraviolet and anti-static PVC sandwich cloth; it is characterized in that PVC layers are arranged outside the two sides of the base cloth layer; The structure, on the one hand, takes into account the low cost of PVC, and the characteristics of easy welding and bonding. On the one hand, PVC has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, and flame resistance; Bearing capacity, impact resistance and shock absorption perfor...
