Problems solved by technology

[0003] At present, the common floors in the market are mainly solid wood flooring, solid wood composite flooring and laminate flooring. The common disadvantages of these floors are that their surface hardness, dimensional stability and anti-warping performance are not good, and they are greatly affected by environmental factors. Under the action of continuous stress, it will produce creep type, and even fracture will affect the service life, and consume a lot of natural resources in the production process, affect the ecological balance of the natural environment, and the production cost is also high

Abstract

The invention belongs to the technical field of indoor floor, and more specifically relates to an indoor floor and preparation technology thereof. The indoor floor is composed of a SPC surface layer and a bamboo plastic foamed core layer; the SPC surface layer is prepared through raw material mixing, extrusion, and thickness determination; the bamboo plastic foamed core layer is prepared through injection of raw materials into a torque rheometer for banburying and injection moulding using an injection machine; and at last combination is carried out so as to obtain the indoor floor. The invention also discloses preparation methods of modified bamboo powder and a modified plasticizer; bamboo powder is modified with the modified plasticizer, the hot melt fluidity is improved, sheet material plasticizing torsion force is reduced effectively, energy consumption is reduced, and cost is reduced. The indoor floor is excellent in flexibility, size stability, and warping resistance, and the market prospect is better than that of conventional sheet materials.

Description

Technical field: [0001] The invention relates to the technical field of indoor floors, in particular to an indoor floor and a preparation process thereof. Background technique: [0002] With the progress of industry and the gradual improvement of people's living standards, people's tastes for living environment and decoration are also constantly improving. As an important part of home furnishing, flooring is increasingly attracting people's attention. [0003] At present, the common floors in the market are mainly solid wood flooring, solid wood composite flooring and laminate flooring. The common disadvantages of these floors are that their surface hardness, dimensional stability and anti-warping performance are not good, and they are greatly affected by environmental factors. Under the action of continuous stress, creep deformation will occur, and even fracture will affect the service life, and a large amount of natural resources will be consumed in the production process,...
