Problems solved by technology

[0003] However, although the PVC material does not produce an open flame, it has the defect of being easy to burn, and it will also produce a large amount of toxic smoke during combustion, and it is also more likely to have hidden dangers of combustion. An important direction of the product
Especially the water-based flame-retardant gray glue-backed PVC, adding both flame retardant and gray paste, makes the performance of the glue worse, and it is easy to cause more residual glue.

Abstract

The invention relates to digital image receiving materials, especially to a preparation method of water-based flame-retardant grey gum type back glue PVC. The preparation method of the water-based flame-retardant grey gum type back glue PVC comprises the following steps: (1) preparing a flame-retardant coating; (2) preparing a flame-retardant glue layer; (3) coating a white PVC layer with 15-30 g/m<2> of the flame-retardant coating, drying, coating the other surface of the white PVC layer with 15-30 g/m<2> of the flame-retardant glue layer at the coating speed of 20-40 m/min, drying, gluing the white PVC layer with the release white silicon paper layer, and rolling. The flame retardant property of the water-based flame-retardant grey gum type back glue PVC prepared by the above preparationmethod can reach fireproofing grade of VTM-2; and the product has high color reduction degree, 100% removes residual glue and can be applied to water-based spray painting and portray printing equipment.

Description

technical field [0001] The invention relates to a digital image receiving material, in particular to a preparation method of water-based flame-retardant gray glue type back glue PVC. Background technique [0002] In recent years, green and environmentally friendly products have attracted people's attention, and the government has also vigorously advocated environmental protection. More than 80% of adhesive-backed PVC products in the market today use oil-based glue, which contains carcinogenic chemical components such as benzene or releases VOC gases that are harmful to the environment. [0003] However, although the PVC material does not produce an open flame, it has the defect of being easy to burn, and it will also produce a large amount of poisonous smoke during combustion, and it is also more likely to have hidden dangers of combustion. An important direction of the product. Especially for water-based flame-retardant gray glue-backed PVC, both flame retardant and gray ...
