Wollastonite modified thermoplastic resin composite material and product preparation method thereof

Abstract

The invention relates to a wollastonite modified thermoplastic resin composite material which comprises the following raw materials in percentage by weight: 50 to 70 percent of wollastonite, 25 to 40 percent of polypropylene, 3 to 6 percent of maleic anhydride modified polypropylene, 1 to 3 percent of titanium dioxide and 1 to 2 percent of anti-oxidant. The invention also provides a method for preparing sanitary ware, hardware of the sanitary ware, outdoor products, exterior wall decorative pipes, practical decoration of public landscape and other products with the wollastonite modified thermoplastic resin composite material. The method has the advantages of easily available raw materials, no need of high energy consumption and long-termed firing during the preparation process, greatly reduced energy consumption, high mechanical automation degree, reduced labor intensity and high yield, and the products fully meet the requirements of industrial and large-scale production.

Description

technical field [0001] The invention relates to a thermoplastic resin composite material, in particular to a wollastonite-modified thermoplastic resin composite material and a method for preparing products using the material. The composite material can be used to make sanitary ware, sanitary ware hardware, outdoor products, External wall decorative pipes are practical decorative products for public landscapes. Background technique [0002] Common sanitary ware includes bathtubs, basins, toilets, and urinals. Most of them are made of clay. First, the clay is made into sanitary ware products for firing. A large amount of coal or natural gas causes a large amount of carbon emissions and energy consumption, and the amount of carbon emissions is large, especially air pollution; and during the firing process, due to temperature asymmetry, the product cracks and deforms, resulting in a large number of defective products and Scrap, forming secondary pollution and cost increase.

[0002] Common sanitary ware includes bathtubs, basins, toilets, and urinals. Most of them are made of clay. First, the clay is made into sanitary ware products for firing. A large amount of coal or natural gas causes a large amount of carbon emissions and energy consumption, and the amount of carbon emissions is large, especially air pollution; and during the firing process, due to temperature asymmetry, the product cracks and deforms, resulting in a large number of defective products and Scrap, causing secondary pollution and cost increase

At the same time, the clay resources used in production are becoming increasingly scarce. Once the resources are exhausted, it will no longer be possible to use clay to produce sanitary ware products

[0003] Recently, artificial agate or acrylic has been used to prepare sanitary ware. See the Chinese invention patent "Acrylic toilet made by pouring process" (authorized announcement number: CN126923C) with the patent number ZL200410040962.6. The components are all prepared by pouring the mixture of resin and agate powder into the interlayer hollow shell to prepare the toilet. Although the obtained product has the general characteristics of ceramic products, the method is relatively complicated, the product has poor appearance, poor practicability, and a large number of Consumption of petroleum by-products, poor self-cleaning performance

On this basis, another toilet with composite structure of acrylic and fiberglass is disclosed, see the Chinese utility model patent "toilet with composite structure of acrylic and fiberglass" (authorized announcement number: CN2926350Y) whose patent number is ZL200620034821.8, but its The appearance looks like a plastic product, but the sensory, durability and usability are poor

[0004] China Invention Patent Application No. 96106392.0 Chinese Invention Patent Application Publication "Artificial Marble Products and Its Preparation Method" (publication number: CN1167741A), the application mainly uses marble powder, unsaturated polyester resin, aluminum hydroxide and wollastonite The raw materials are finished by pouring process. Although the product performance and preparation process have been improved, the product is bulky, the process is poor in practicability, the flatness and finish are poor, and the labor efficiency is low, especially the conditions for industrialized mass production cannot be formed.
