Embodiment Construction

[0015] Below in conjunction with accompanying drawing, patent of the present invention is described further.

[0016] like figure 1 As shown, a "multifunctional soft wall base material" production process and formula, including production process and coating formula, is characterized in that: the coating formula includes the surface layer (T1) PU layer, the second layer (low hair foam layer) (T2), three layers (adhesive layer, low foam layer) (T3) composed of the front base fabric of the base fabric and the bottom layer of the base fabric (high foam layer) (T4); this substrate is produced in A new process based on the traditional release paper production line (see the soft wall substrate process flow chart), the carrier Z is the release paper, the entire substrate is carried on the release paper for processing, and ZA is the release paper unwinding , ZB is the release paper storage rack, the release paper is coated with T1 (formulation P1) as the surface layer, enters H1 for ...

Abstract

The invention relates to a multifunctional soft wall base material production process and formula. The multifunctional soft wall base material comprises T1, T2 and T3 (adhering layer) in the front. T1 is a PU (polyurethane) layer which is used for increasing surface anti-scratch strength, adding negative ion powder materials, and allowing the soft wall base material to have a negative ion releasing function. T2 is a support layer which is used for supporting embossed printing. Foaming agent is added to the adhering layer T3 to allow T3 to have the same foaming effect as T2, and weight of the soft wall base material is reduced and softness of the same is increased. Foaming ratio of T2 and T3 is controlled at 1.2-1.8 times according to different requirements of the soft wall base material. After cloth applying, a high-foaming material T3 layer is coated at the bottom of base cloth to increase internal space of the soft wall base material, achieve thermal insulation and softness, and facilitate wall adhering. Diatomaceous earth is added in the formula and one-step foaming is used to allow cells of the whole soft wall base material to be communicated so as to achieve breathability, and accordingly the soft wall base material has functions of breathability, moisture permeability, moisture adjusting by balancing moisture regain and water retention rate, and deodorization.

Description

technical field [0001] The patent of the present invention relates to a production process and formula in which PVC material is used to foam both the front and the bottom of the base fabric; the front and bottom have different expansion ratios; the front and the bottom are both completed in the same foaming oven. Background technique [0002] Usually, in the PVC production process, one or two layers of PVC material are coated on one side of the base fabric for single-layer foaming, which cannot meet the requirements of producing a kind of fabric with good dimensional stability, heat preservation, sound insulation, and ability to release negative ions. Paste performance and other multi-functional plastic soft walls are required as interior decoration materials. Contents of the invention [0003] The production process and formula of a "multifunctional soft wall base material" provided by the present invention, the adopted technical scheme is: [0004] A "multifunctional so...
