Abstract

The invention discloses a colorful SMC material applied to bathroom products, which comprises the following components in percentage by weight: 65.9-73% of continuous-phase resin paste, 1-3% of dispersed-phase color matching base paint, 1-1.6% of a thickener and 25-30% of alkali-free glass fibers, and the sum of the weight percentages of the components is 100%. The invention also provides a preparation method of the colorful SMC material. The colorful SMC material disclosed by the invention has the advantages of good surface gloss, various colors, good product color stability, good mechanicalstrength and simple production process.

Description

technical field [0001] The invention belongs to the field of chemical composite materials, and in particular relates to a colorful SMC material used in sanitary products and a preparation method thereof. Background technique [0002] Thermosetting resin glass fiber reinforced composite material, Sheet Molding Compound (SMC for short), is a kind of glass fiber reinforced composite material. It is based on unsaturated polyester resin, low shrinkage additives, thickeners, initiators, mold release agents, fillers, colorants, etc. mixed into a resin paste, and then impregnated with chopped glass fiber roving or glass chopped mat, and on both sides The "sandwich" molding compound formed by wrapping polyethylene or polypropylene film can be used after a certain period of aging. The SMC molding process is currently mainly molded, solidified and demolded under heating and pressure conditions to obtain a closed-film molding composite material technology for the desired product. Comp...
