Embodiment 1

[0055] The resin, microspheres, pigments, additives, and solvents were mixed according to the contents described in the following Table 1 (unit: parts by weight) to prepare a texture coating composition. The prepared composition was coated on a center trim, which is a plastic part for automotive interiors, which is injection-coated with a PC / ABS material, and dried at 95° C. for 40 minutes to form a coating film layer.

[0056] Such as Figure 4 As shown, it can be confirmed that fluffing is completed, the surface gloss is lost due to the drying of the coating film, and a part of the swollen microspheres is exposed to the surface of the coating film due to the expansion of the microspheres, thereby achieving a surface texture. In addition, plastic parts were attached to the cockpit module (Cockpit Module) to conduct a heat resistance cycle test of the module. The test method is to measure the distance and step difference between the center decoration and the surrounding plast...

Embodiment 2

[0058] In Example 2, except having changed each component as shown in Table 1 below, the coating film was formed by the same method.

Abstract

The present invention relates to a composition for texture coating of automobile parts and an automobile part comprising a coating film formed from the composition. The composition for texture coating of automobile parts comprises: 20 to 50% by weight of a thermosetting resin; 1 to 10% by weight 3 to 20% by weight of pigments; 1 to 20% by weight of additives; and the remaining amount of solvent; and 5 to 20% by weight of hardener can be added subsequently.

Description

technical field [0001] The present invention relates to a composition for texture coating of automobile parts and an automobile part comprising the composition. Background technique [0002] Currently, soft resins and surface texture modifiers are used in texture-forming paints used for automotive interior / exterior parts. Texture-forming paints are applied to automotive parts materials to express a certain texture. [0003] Texture paints containing polyester resin and silicon as well as urethane or acrylic beads have high softness due to the use of polyester alone, which can maximize the texture perceived by consumers, but poly The characteristic of ester is that it has low weather resistance, so if it is exposed to sunlight for a long time, it may cause discoloration, cracks and other defects in the coating film. Furthermore, although the paint containing polyester and polycarbonate diol has better physical properties than a composition containing polyester alone, it is ...
