Abstract

The invention discloses a method for preparing an environment-friendly high-property bamboo floor. The method includes the following steps that (1) materials are obtained, specifically, the bamboo outer skin and bamboo inner skin of purchased raw bamboos are removed, and then the bamboos are cut off and cut to form bamboo strips which are equal in size; (2) surface treatment is performed, specifically, the bamboo strips are subjected to carbonizing treatment and plasma surface treatment; (3) impregnation is performed, specifically, the bamboo strips which are already subjected to surface treatment are soaked in urea resin for two hours, and the impregnated bamboo strips are dried in a constant temperature drying oven for two to five hours; (4) assembling and hot-pressing are performed, specifically, the impregnated bamboo strips are assembled as required and then subjected to hot-press forming; (5) surface polishing is performed, specifically, formed crude products are subjected to surface polishing so as to meet the requirements for brightness and smoothness; and (6) paint spraying is performed, specifically, a layer of transparent and electric paint is sprayed to the polished bamboo floor, and therefore, the finished bamboo floor is obtained. The bamboo floor prepared through the method has the good characteristics of being physically beneficial, environmentally friendly, waterproof, fireproof and attractive in appearance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a preparation method of an environment-friendly high-performance bamboo floor. Background technique [0002] Traditional wood flooring is loved by consumers because of its natural beauty and excellent environmental protection performance. However, my country's forest resources are poor and cannot meet the market demand for wood. As an alternative derivative of wooden flooring, bamboo flooring has quickly become a new favorite in the field of building materials due to its unique advantages. Bamboo flooring retains the natural texture of bamboo, which is fresh and elegant, and caters to Chinese consumers' love for bamboo since ancient times. [0003] The current bamboo flooring production process needs to be dipped in phenolic resin, and phenolic resin will release formaldehyde in the later treatment process, which will affect people's physical and mental health. At the same time...
