Problems solved by technology

[0005] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the fact that plastic wood is often prepared by mixing plastic and wood powder in the prior art, so it has the characteristics of wood powder, and it is very easy to cause long-term problems due to environmental problems in actual use. Bacteria, thus greatly affecting the performance and service life of the plastic wood, leading to the problem of a greatly increased scrap rate, thereby providing a self-suicidal bacterium, which can ensure that the bacterium is less harmful to it even in an environment with many bacteria.

[0024] The present invention also provides a method for preparing plastic wood by suicide bacteria, wherein, the preparation method includes:

[0025] 1) Mix water, polyvinyl acetate emulsion, polyvinyl alcohol, ethylene glycol, nano-silica, methylchloroisothiazolinone and sodium benzoate to prepare a bactericidal coating M1;

[0026] 2) Apply the bactericidal coating M1 prepared in step 1) on the outer surface of the plastic-wood substrate to obtain a bactericidal plastic-wood; wherein,

[0027] Relative to 100 parts by weight of the water, the amount of polyvinyl acetate emulsion is 30-70 parts by weight, the amount of polyvinyl alcohol is 10-30 parts by weight, and the amount of ethylene glycol is 20-50 parts by weight. In parts by weight, the amount of nano silicon dioxide is 5-15 parts by weight, the amount of methylchloroisothiazolinone is 0.1-2 parts by weight, and the amount of sodium benzoate is 0.1-1 parts by weight.

[0028] In a preferred embodiment, in order to f...

Embodiment 1

[0036] 1) Put 100g water, 40g polyvinyl acetate emulsion, 15g polyvinyl alcohol, 30g ethylene glycol, 8g nano silicon dioxide, 1g methyl chloroisothiazolinone and 0.5g sodium benzoate at a stirring speed of 300r / min Stir and mix under certain conditions to prepare the bactericidal coating M1;

[0037] 2) Apply the bactericidal coating M1 prepared in step 1) on the outer surface of the plastic-wood substrate to a thickness of 0.1 mm to prepare the bactericidal plastic-wood A1.

Embodiment 2

[0039] 1) 100g water, 60g polyvinyl acetate emulsion, 25g polyvinyl alcohol, 40g ethylene glycol, 12g nano silicon dioxide, 2g methyl chloroisothiazolinone and 1g sodium benzoate are placed in a stirring speed of 600r / min Stir and mix under the conditions to prepare the bactericidal coating M1;

[0040] 2) Apply the bactericidal paint M1 prepared in step 1) on the outer surface of the plastic-wood substrate to a thickness of 1 mm to prepare the bactericidal plastic-wood A2.

Abstract

The invention discloses a bactericidal plastic-wood material composition, a bactericidal plastic-wood product and a production method of the bactericidal plastic-wood product. The composition comprises a plastic-wood matrix and bactericidal coating applied to the outer surface of the plastic-wood matrix. The bactericidal coating comprises water, polyvinyl acetate emulsion, poly(vinyl alcohol), ethylene glycol, nanosilicon dioxide, CMIT and sodium benzoate. Specifically, to 100 parts of water by weight, there are 30-70 parts of polyvinyl acetate emulsion, 10-30 parts of poly(vinyl alcohol), 20-50 parts of ethylene glycol, 5-15 parts of nanosilicon dioxide, 0.1-2 part of CMIT and 0.1-1 part of sodium benzoate. According to the design, the composition is bactericidal; and invasion of bacteria to the composition is weak even in an environment full of bacteria.

Description

technical field [0001] The invention relates to the field of production and preparation of plastic wood, in particular, to a composition of a bactericidal wood plastic material, a bactericidal wood plastic and a preparation method thereof. Background technique [0002] With the depletion of global resources and the increasing social awareness of environmental protection, higher requirements are placed on the application of wood and petrochemical products in production and life. As an emerging environmentally friendly material, wood-plastic material is mainly made of plant fiber materials, and plastics are added to form a composite material with wide applicability. Because it has the advantages of both plant fibers and plastics, it can be used in a wide range of practical applications. [0003] However, because plastic wood is often prepared by mixing plastic and wood powder, it has the characteristics of wood powder. In actual use, it is very easy to cause bacteria to grow ...
