Embodiment 1

[0070] Preparation of nano-silver ion modified carbon black antibacterial agent is prepared by the following method:

[0071] 1) reacting an aqueous solution of a soluble silver salt with a concentration of 2M and ammonia to form a silver-ammonia complex alkaline aqueous solution; wherein the molar ratio of the aqueous solution of a soluble silver salt to ammonia is 1:10;

[0072] 2) Add carbon black to hydrogen peroxide, mix well and let it stand for 60 minutes, then add it to the alkaline aqueous solution of silver ammonia complex prepared in step 1) to carry out the reduction reaction. After the completion, the precipitate is separated and washed, and the obtained brown-black solid is nano Silver particles modify carbon nanotubes; the mass of carbon black is 0.5 times the mass of the silver ion; the molar amount of hydrogen peroxide is twice the molar mass of the silver ion.

Embodiment 2

Abstract

The invention relates to a wood-plastic bathroom plate. The wood-plastic bathroom plate comprises a surface layer and a bottom layer, and the surface layer comprises 1-2 parts by weight of a nanometer silver-ion modified carbon black antibacterial agent. Compared with conventional wood-plastic materials, the wood-plastic bathroom plate has the following advantages: 1) the wood-plastic bathroom plate is capable of well resisting bacteria and preventing mildew because the surface of the plate posses the antibacterial layer, and the wood-plastic bathroom plate has relatively good waterproofness because the antibacterial layer on the surface is relatively low in porosity; and the wood-plastic bathroom plat is wide in raw material resource, low in cost, energy-saving and environment-friendly, and is an ideal bathroom decoration plate replacing common density plates and multi-layer plates; 2) the wood-plastic bathroom plate is easy to process without being limited by processing length, has hard and flat surface crust which does not need manually polishing, helps to save labor resource, and is 100% recyclable after being used for years; and 3) the production technology is simple and easy to operate, and the wood-plastic bathroom plate is good in stability and easy to process.

Description

technical field [0001] The invention relates to the field of wood-plastic materials, in particular to a formulation of wood-plastic materials used as bathroom boards and a preparation method thereof. Background technique [0002] Wood-plastic composite material is a material made of wood powder, wood fiber or plant fiber filled thermoplastic polymer through high temperature and high pressure treatment. It has the advantages of both wood and plastic. Its main raw material is agricultural and forestry waste (such as waste wood, crops, rice straw, etc.) and thermoplastics. As a by-product of agricultural production, crop straw has a large output and is widely distributed. According to statistics, the current production of crop straw in my country is about 800-1000 million tons per year. For a long time, extensive research has been done on the comprehensive utilization of crop straws at home and abroad, and some available methods have been obtained, one of the important ones is...
