A kind of outdoor heavy bamboo wood floor and preparation method thereof

Abstract

The invention discloses an outdoor heavy bamboo and wood floorboard and a preparation method thereof. The outdoor heavy bamboo and wood floorboard comprises a heavy bamboo and wood floorboard substrate, wherein a sealed bottom layer, an attached primer layer, a first finish paint layer and a second finish paint layer are sequentially coated on the heavy bamboo and wood floorboard substrate from inside to outside; each of the first finish paint layer and the second finish paint layer is UV finish paint; the attached primer layer is UV attached primer; the sealed bottom layer is waterborne UV sealed bottom. The preparation method of the floorboard comprises the following steps that the waterborne UV sealed bottom is coated on each surface of the heavy bamboo and wood floorboard substrate; infrared levelling is implemented; primary UV curing is performed; the UV attached primer is coated on the upper surface of a board material; secondary UV curing is performed; the UV finish paint is coated on the upper surface of the board material once, and UV curing is performed; the UV finish paint is coated again, and the UV curing is performed; the outdoor heavy bamboo and wood floorboard is obtained. The outdoor heavy bamboo and wood floorboard has the advantages that the antifungal rate is high; the wearing resistant performance is good; the weather resistance is good; the production efficiency is high; the environmental protection performance is good.

Description

technical field [0001] The invention relates to the technical field of outdoor floors, in particular to an outdoor heavy bamboo wood floor and a preparation method thereof. Background technique [0002] The heavy bamboo wood floor itself has the disadvantages of being easily deformed and not resistant to heat and humidity. The outdoor heavy bamboo wood floor needs to be laid outdoors for use, and it needs to withstand rain, snow, wind, and sun for a long time. The outdoor humid environment is more likely to make the heavy bamboo and wood materials suffer from mold and decay bacteria, which can easily cause the floor to crack, deform, moth-eaten or mildew. [0003] Using anti-mildew and anti-bacterial agent for chemical protection treatment or coating wood wax oil, two-component varnish, etc. is currently the main anti-mildew treatment method for outdoor heavy bamboo wood floors. However, the use of antifungal and antibacterial agents for chemical protection treatment has pr...

AI Technical Summary

Problems solved by technology

However, the use of antifungal and antibacterial agents for chemical protection treatment has problems such as high cost, complicated process, short performance maintenance time, and a large amount of volatile organic compounds released during use to pollute the environment; coating wood wax oil, two-component varnish, etc. Improving the anti-mildew performance has limited effect, especially the control effect on blue-stain bacteria is not good, and the abrasion resistance of the coating film is low (500g wear-resistant revolutions are about 200r and 300r respectively), and the coating production efficiency is not high
