Embodiment 1

[0070] The preparation of nano silver ion modified carbon black antibacterial agent adopts the following method:

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

[0072] 2) Add carbon black to hydrogen peroxide solution, mix well and let it stand for 60 minutes, add it to the alkaline aqueous solution of silver ammonia complex prepared in step 1), carry out the reduction reaction, separate the precipitate and wash after the end, the brown-black solid is the nanometer Silver particles modified carbon nanotubes; the mass of carbon black is 0.5 times the mass of the silver ions; the molar amount of hydrogen peroxide is 2 times the molar mass of the silver ions.

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 formula of wood-plastic materials used as bathroom panels 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 with thermoplastic polymer and processed by high temperature and high pressure. It has the advantages of 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 a wide distribution. According to statistics, the current crop straw production in my country is about 800 to 1 billion tons per year. For a long time, extensive research has been carried out on the comprehensive utilization of crop stalks at home and abroad, and some available ways have been obtained. One of the important ones is to blend ...
