Problems solved by technology

[0003] The performance of the luminescent floor studied at present is relatively single, and the research on the preparation of multi-functional composite floor is not perfect
As reported in Chinese Invention Patent No. 201610748458.4, organically modified fluorescent materials are used as luminescent pigments to be mixed with wood-plastic floor co-extrusion materials to prepare luminescent floors. On the one hand, it is not considered that the fluorescent materials may be under the wood powder during the mixing process, which makes it unable to absorb energy. , so that the afterglow performance is reduced; on the other hand, the performance is single, only light emission is considered, and the problem of quenching of some fluorescent materials by water is not considered
The luminescent cork rubber composite floor disclosed in Chinese invention patent 201610470606.0 directly spreads the alumina phosphor powder without any surface treatment on the slab, which cannot guarantee interface compatibility and may cause water quenching

Abstract

The invention discloses energy-saving self-luminous laminate flooring and a preparation method thereof. The flooring comprises a lower base material layer, a middle base material layer, a printing layer and an ultraviolet curing wear-resistant coating which are arranged from bottom to top sequentially and manufactured integrally, wherein the middle base material layer and the lower base material layer are made of a hollow glass bead doped and modified resin material, and the ultraviolet curing wear-resistant coating is made of an ultraviolet curing coating doped and modified with hollow glassbeads and long afterglow powder. The preparation method comprises the following steps: firstly, the hollow glass beads and the long afterglow powder are subjected to surface modification and then fully mixed with the resin material, an auxiliary and the like, and the finished laminate flooring is prepared by hot pressing, printing, film evaporation, tempering, curing, punching and the like. The laminate flooring has the advantages of being long in afterglow time, high in brightness, good in stability, good in heat preservation performance, environmentally friendly, non-toxic, pollution-free, radioactivity-free, energy-saving, consumption-reducing, attractive, practical and wide in application prospect.

Description

technical field [0001] The invention relates to the field of flooring, in particular to a composite flooring with energy saving, heat preservation, good decoration and self-luminous function. Background technique [0002] Building energy consumption is one of the important components of the total energy consumption of human beings, and it is also the main source of pollution. Reducing the energy consumption of buildings mainly depends on the thermal insulation effect of building exterior walls, roofs, floors, partition walls, doors and windows, and the wall enclosure structure, which accounts for 60% of the building structure, is the main source of heat transfer in buildings. Parts, the proportion of energy consumption is the largest. Therefore, using high-efficiency thermal insulation materials to insulate walls is one of the main energy-saving measures, and it is also the most effective way. The combination of hollow microspheres and long-lasting luminescent materials is...
