BMC formula for manufacturing kitchen and bath supplies

Abstract

The present invention relates to a novel material for manufacturing kitchen and bath supplies, and especially a BMC formula for manufacturing kitchen and bath supplies and a preparation method of the material. Status quo in the field of kitchen and bath supplies manufacture at the present stage are shown as follows: the BMC formula for manufacturing kitchen and bath supplies provided by the invention is characterized by comprising the following components by weight parts: 120-150 parts of aluminium hydroxide, 450-500 parts of calcium carbonate, 60-80 parts of shrinkage agent, 10-20 parts of release agent, 175-205 parts of glass fiber, 220-240 parts of unsaturated polyester resin, 35-45 parts of styrene, 1.4-1.6 parts of magnesium oxide, 7-12 parts of titanium, 0.3-0.4 parts of 1.75-2.1 parts of polymerization inhibitor, and 5-7.5 parts of curing agent. The BMC thermosetting material composed of a specific formula provided by the invention can be formed into a plurality of kitchen and bath supplies through mould pressing, injection or transfer by mechanized and automatic equipment, and can improve appearance gloss of the product, overall strength and quality of the kitchen and bath supplies, prolong service life, and improve production efficiency and reduce production cost.

Description

technical field [0001] The invention relates to a novel raw material for manufacturing kitchen and sanitary products, in particular to a BMC formula for manufacturing kitchen and sanitary products and a preparation method thereof. Background technique [0002] The status quo in the field of kitchen and bathroom product manufacturing at this stage is as follows: [0003] 1. Use the traditional ceramic manufacturing process to burn kitchen and bathroom products, such as toilets and face washers, at high temperatures (>1200°C). The disadvantages of this method are large investment, high energy consumption, and long production cycle; [0004] 2. Use thermoplastics or phenolic, urea-formaldehyde and other resins to produce kitchen and bathroom products and accessories, such as water tanks, small tank accessories, toilet covers, etc. The disadvantages are: thermoplastic products have low strength, poor surface scratch resistance, and are flammable. Phenolic and urea-formaldehy...

AI Technical Summary

Problems solved by technology

[0003] 1. Use the traditional ceramic manufacturing process to burn kitchen and bathroom products, such as toilets and face washers, at high temperatures (>1200°C). The disadvantages of this method are large investment, high energy consumption, and long production cycle;

[0004] 2. Use thermoplastics or phenolic, urea-formaldehyde and other resins to produce kitchen and bathroom products and accessories, such as water tanks, small tank accessories, toilet covers, etc. The disadvantages are: thermoplastic products have low strength, poor surface scratch resistance, and are flammable. Phenolic and urea-formaldehyde products are brittle, easy to break, and have poor appearance gloss;

[0005] 3. Use FRP cold forming technology to make large kitchen and bathroom products, such as bathtubs, shower trays, etc. The disadvantage of this method is that it needs to be sprayed twice, the cycle is long, the production efficiency is low, and the surface adhesion is not enough;

[0006] 4. The production of kitchen and bathroom products, such as bathtubs and water tanks, using metal materials such as cast iron or stainless steel, has the disadvantage that the resulting products are relatively bulky, and some also require secondary coating, and the price is often higher
