Embodiment 1

[0021] The following part of this embodiment describes the composition and preparation method of raw materials in this embodiment:

[0022] Prepare 25 kg of phthalic resin; 12 kg of polystyrene; 20 kg of glass fiber; 40 kg of calcium carbonate; 0.5 kg of TBPB; 0.5 kg of MgO; kilogram.

[0023] Ortho-phenyl resin, polystyrene, calcium carbonate, TBPB, MgO, zinc stearate, 2-imidazoline-5-thione derivatives are strictly measured and fully mixed in advance, and then become a paste mixture (resin paste). The resin paste passes through the SMC unit, and the glass fiber chopped into 25.4mm is impregnated, bubbled, compacted and other processes to make an SMC sheet. After the sheet is matured, the viscosity reaches the molded viscosity range and is stable. Molded to obtain an antibacterial SMC molded material, and the antibacterial rate of the material after standing for 24 hours can reach 94.5%.

Embodiment 2

[0025] The following part of this embodiment describes the composition and preparation method of raw materials in this embodiment:

[0026] An antibacterial sheet molding compound and a preparation method thereof, the components of the sheet molding compound are by mass fraction:

[0027] 23 parts of isophthalic resin; 15 parts of polyvinyl acetate; 20 parts of glass fiber; 35 parts of talcum powder; 0.25 parts of TBPO; 0.25 parts of MgO; 5 servings.

[0028] The preparation method is the same as in Example 1. The antibacterial sheet molding compound has the following properties: tensile strength 90MPa, bending strength 165MPa, impact strength 85kJ / m2, oxygen index 36 (belonging to B1 grade), and the antibacterial rate after standing for 24 hours can reach 94.8%.

Embodiment 3

[0030] The following part of this embodiment describes the composition and preparation method of raw materials in this embodiment:

[0031] An antibacterial sheet molding compound and a preparation method thereof, the components of the sheet molding compound are by mass fraction:

[0032] 30 parts of vinyl resin; 14 parts of polyvinyl acetate; 28 parts of glass fiber; 25 parts of talcum powder; 25 parts of aluminum hydroxide; 0.8 parts of TBPO; 0.7 parts of MgO; - 0.6 parts of thione derivatives.

[0033] The preparation method is the same as in Example 1. The antibacterial rate of the antibacterial sheet molding compound after standing for 24 hours can reach 94.1%.

Abstract

The invention relates to the field of composite materials, in particular to an antimicrobial sheet molding compound and a preparation method thereof. The antimicrobial sheet molding compound comprises the following raw material components in parts by weight: 15-30 parts of unsaturated polyester resin, 5-15 parts of low shrinkage agent, 10-30 parts of fibre glass, 35-55 parts of inorganic filler, 0.2-1 part of evocating agent, 0.2-1 part of thickening agent, 1-3 parts of mold lubricant and 0.5-5 parts of antibacterial agent. The invention has the advantages of reasonable prescription design, high efficiency, innocuity and good antimicrobial effect.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to an antibacterial sheet molding compound and a preparation method thereof. Background technique [0002] Ordinary glass fiber reinforced unsaturated polyester sheet molding compound is composed of unsaturated polyester resin, glass fiber, filler and auxiliary materials. It has the characteristics of chemical corrosion resistance, light weight and high strength, good fatigue resistance and excellent anti-aging performance. , sheet molding compound and its molded products are widely used, such as SMC doors, bathroom products, office furniture, etc., but the existing molded products have no self-antibacterial function, and many bacteria are often attached to the surface of these material products, which endanger the health of the crowd healthy. [0003] At present, my country has not yet produced glass fiber reinforced unsaturated polyester sheet molding compound with antibacteria...
