Embodiment Construction

[0014] The patent of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] like figure 1 As shown, a production process and formulation of a multifunctional soft wall base material, including production process and coating formulation, is characterized in that: the coating formulation comprises a surface layer (T1) PU layer, a two-layer (low-foaming layer) ) (T2), three layers (adhesive layer, low foam layer) (T3) consisting of the front base fabric of the base fabric and the bottom surface layer (high foam layer) (T4) of the base fabric; this substrate is produced by traditional The new process based on the release paper production line (see the process flow chart of the soft wall substrate), the carrier Z is the release paper, the whole substrate is carried on the release paper for processing, ZA is the release paper unwinding, ZB is the release paper It is a release paper storage rack. The release paper passes through...

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 both the front surface and the bottom surface of the base fabric are foamed with PVC material; the front surface and the bottom surface have different foaming ratios; 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 product with good dimensional stability, heat preservation, sound insulation, negative ion release, and good air quality. Multifunctional plastic soft walls such as adhesive properties are required as interior decoration materials. SUMMARY OF THE INVENTION [0003] The invention provides a production process and formulation of a multifunctional soft wall base material, and the adopted technical scheme is: a production process and formulation of a multifunctional soft wall b...
