Preparation method of photo-catalytic nano wood-plastic board

Abstract

The invention relates to a method for preparing photocatalyst nanometer wood-plastic boards. The method comprises the following steps: a) 50 to 100 portions by weight of wood meal and 2 to 4 portions by weight of aluminum-zirconium treatment agent are added in turn to a horizontal stirrer and stirred for 2 to 3 hours at a temperature between 100 and 120 DEG C; b) the treated wood meal and resin are put into a high-speed kneader in the mass ratio of 1:2, mixed with 7 to 40 portions by weight of additive, and are stirred for 10 to 15 minutes at the temperature between 100 and 120 DEG C, unloaded to a low-speed mixer and stirred to normal temperature; c) the mixed materials are put into a board extrusion device and subjected to vacuum and cooling setting and two-roller calendering setting so as to product a board, and the board is cut with fixed-length; and d) the surface of the board is sprayed with a layer of photocatalyst nanometer material, so as to obtain a finished product. The method has the advantages of low cost, extensive resource and good decorative effect, and more importantly, the method can utilize natural light to sterilize, thereby achieving the effect of purifying air.

Description

technical field [0001] The invention relates to a preparation method of a wood-plastic board, in particular to a preparation method of a photocatalyst nano-wood-plastic board. Background technique [0002] In the prior art, all kinds of composite boards used for decorating furniture and decoration floors made by composite technology usually only have ordinary decorative functions and have no antibacterial function, while wooden furniture and wooden floors are easily polluted and breed various bacteria. [0003] The furniture of home or office buildings, building materials such as paint and wooden floors used for decoration, and interior materials of automobiles will produce a large amount of toxic gases, especially in newly renovated houses, which will produce a lot of toxic gases such as formaldehyde, toluene, ammonia and volatile gases. Ordinary wood-plastic panels do not have the function of decomposing these gases, and cannot effectively inhibit bacteria such as Escheri...

Problems solved by technology

[0002] In the prior art, all kinds of composite boards used for decorating furniture and decoration floors made by composite technology usually only have ordinary decorative functions and have no antibacterial function, while wooden furniture and wooden floors are easily polluted and breed various bacteria

[0003] The furniture of home or office buildings, building materials such as paint and wooden floors used for decoration, and interior materials of automobiles will produce a large amount of toxic gases, especially in newly renovated houses, which will produce a lot of toxic gases such as formaldehyde, toluene, ammonia and volatile gases. Ordinary wood-plastic panels do not have the function of decomposing these gases, and cannot effectively inhibit bacteria such as Escherichia coli and Staphylococcus aureus

[0004] At present, most of them use some products such as air purifiers to purify the air, but it is difficult to implement in public places and places with relatively large areas, or the effect is not good, such as shopping malls, stations, conference halls, hospitals, and company offices. Wait

Ordinary wood-plastic panels can only complete the decoration of these places, but they cannot achieve the effects of purifying the air and inhibiting the spread of bacteria.
