Problems solved by technology

[0007] The above-mentioned formable sheet becomes a slightly dry state in a low-humidity environment, and the formable sheet becomes hard especially at a low temperature, so the stretchability is insufficient, resulting in poor formability. Problems such as wrinkles occur

Embodiment 1

[0095] Used in the initial phenol-formaldehyde condensate (aqueous solution of 50% by mass solid content), and added in proportions of 0.1, 5.0, 10.0, 20.0, 40.0, and 50.0% by mass to the solid content of the phenol-formaldehyde initial condensate Various mixtures obtained by mixing diethylene glycol (DEG) by stirring and mixing, with a weight per unit area of ​​150 g / m compared to polyester fibers produced by needle punching 2 Fiber sheets of non-woven fabrics, to achieve a coating weight of 30% by mass (solid content) (45g / m 2 ) dipping and coating various mixed liquids with a coating roller, drying at a temperature of 120-130° C. for 2 minutes, and then pre-curing the impregnated initial condensate to stage B to obtain a formable sheet A.

Embodiment 2

[0097]Use in acrylic polymer latex (aqueous solution of 50% by mass solid content), and add and stir in proportions of 0.1, 5.0, 10.0, 20.0, 40.0, 50.0 mass% to the solid content of the acrylic polymer latex Various mixtures of polyethylene glycol (PEG) are used in non-woven fiber sheets made of polyester fibers and made by spunbonding (weight per unit area: 30g / m 2 ) on overlapping glass fibers (weight per unit area: 100g / m 2 ), from the glass fiber surface, the mixed liquid is applied in an amount of 60% by mass (solid content) relative to the glass fiber (60g / m 2 ) was applied with a sprayer, and then dried at a temperature of 120 to 130° C. for 2 minutes to obtain a moldable sheet B with a polyester nonwoven fabric.

Embodiment 3

[0137] By 30 mass parts of sulfomethylated phenol-alkyl resorcinol-formaldehyde initial condensation product (50 mass % solid content aqueous solution), 5 mass parts of ethylene glycol, 1 mass part of carbon black dispersion ( 35 mass % solid content aqueous solution), 2 mass parts of fluorine-based water and oil repellent (20 mass % solid content aqueous solution), 2 mass parts of flame retardant (50 mass % of nitrogen-containing, phosphorus flame retardant Aqueous solution of solid content) and 60 parts by mass of water have a weight per unit area of ​​30 g / m with respect to polyester fibers produced by the spunbond method 2 The fibrous sheet of the non-woven fabric is dip-coated on the fibrous sheet with a coating roller in a coating amount of 45% by mass, and then dried at a temperature of 120 to 130°C for 1 minute, and the impregnated initial The condensate is pre-cured to B-stage to produce a formable sheet. The obtained formable sheet was used as a skin material, and t...

Abstract

The invention provides a formable sheet which exhibits good formability even after the storage at low temperature and humidity. A formable sheet obtained by coating or impregnating a porous material with a synthetic resin, which sheet is further impregnated with a water-retaining agent. The water-retaining agent serves to make the sheet retain a suitable amount of water, whereby the sheet can keep good formability.

Description

technical field [0001] The present invention relates to a formable sheet used as, for example, a skin material of an automobile interior material, and an interior material using the formable sheet. Background technique [0002] Conventionally, for example, as a skin material for automobile interior materials, a formable sheet is provided in which a porous material such as a fiber sheet is impregnated with a synthetic resin to impart formability (for example, refer to Patent Documents 1 to 4). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 11-263170 [0004] Patent Document 2: JP-A-2000-62543 [0005] Patent Document 3: JP-A-2000-327797 [0006] Patent Document 4: JP-A-2003-326628 [0007] The above-mentioned formable sheet becomes a slightly dry state in a low-humidity environment, and the formable sheet becomes hard especially at a low temperature, so the stretchability is insufficient, resulting in poor formability. Problems such as wrinkles occ...
