Embodiment 1）

[0019] The colored gel coat of the sanitary ware of the present embodiment is ivory white, and it is made by the component of following parts by weight:

[0020] 100 parts of matrix resin; among them, 90 parts of medium-active matrix resin, whose molecular weight distribution index (Mw / Mn) ≤ 2.5, specifically adopts the m-phenylene neopentyl glycol type matrix resin of Huari Company's model 251, in which unsaturated di The number of moles of basic acid is 50% of the total number of moles of dibasic acid; 10 parts of highly active matrix resin, its molecular weight distribution index (Mw / Mn) ≤ 2.5, the specific use of Huari company's model is 230 isophthalic new Pentylene glycol-based matrix resin, in which the mole number of unsaturated dibasic acid is 70% of the total mole number of dibasic acid.

[0021] 12 parts of styrene.

[0022] 20 parts of talcum powder.

[0023] Fumed silica 2 parts.

[0024] 0.15 part of thixotropic stabilizer, what adopt is the PR600 type thixotr...

Abstract

The invention discloses a colored gel coat for sanitary ware and a manufacturing method of the colored gel coat. The colored gel coat for the sanitary ware is manufactured by components including, by weight, 100 parts of matrix resin, 8-20 parts of styrene, 10-30 parts of functional filler, 2-3 parts of thixotropic agent, 0.12-0.2 part of thixotropic stabilizer, 0.6-1.2 parts of surface auxiliaries, 10-20 parts of color paste and 0.1-0.4 part of accelerator. The manufacturing method includes weighing the components for use according to formula; firstly placing the matrix resin into a dispersing reactor, adding the functional filler with stirring, dispersing after adding, adding the thixotropic stabilizer, adding the thixotropic agent with stirring, dispersing after adding and obtaining the matrix gel coat; adding the color paste, the styrene, the surface auxiliaries and the accelerator into the gel coat, and uniformly stirring to obtain the colored gel coat for the sanitary ware. The colored gel coat for the sanitary ware is colorful and has excellent resistance to heat and cod impact.

Description

technical field [0001] The invention relates to a gel coat and a preparation method thereof, in particular to a colored gel coat for sanitary ware and a preparation method thereof. Background technique [0002] At present, the materials of sanitary ware are mostly ceramic or enamel, and some are made of acrylic. Among them, the biggest disadvantage of ceramics and enamel is that the comfort is poor, especially when used in winter, it feels cold and very uncomfortable. Although acrylic has better comfort, its wear resistance, stain resistance and weather resistance are not good, and the surface is prone to aging and discoloration. [0003] Gel coat is a surface material with certain thixotropy, good rheology and excellent mechanical properties obtained by adding thixotropic agent and rheological additive to a suitable matrix resin through high-speed dispersion or grinding. Due to its good comprehensive performance, it is widely used in ships, vehicles, buildings, clothing a...
