Embodiment 1

[0041] Embodiment 1: When the induction color-changing material is a temperature-sensitive color-changing material, the polyvinyl chloride matrix is ​​25%-75%, the stone powder is 25%-75%, and the auxiliary agent is 1%-45%, wherein the auxiliary agent is a plasticizer and a stabilizer , titanium dioxide, ultraviolet absorbers, antioxidants, antiaging agents, antistatic agents, dispersants, fluorescent whitening agents, thickeners, pearl mica powder, antibacterial agents, bacteriostatic agents, organic and inorganic pigments, dyes One or more, thermochromic material 0.1‰-40%.

[0042] This kind of temperature-changing floor can change the color system of the floor according to the temperature of the natural environment according to the different requirements of customers. In the specific production or working environment where the ambient temperature is required, the discoloration of the floor can remind the staff to adjust the ambient temperature in time, such as children's ho...

Embodiment 2

[0043] Embodiment 2: When the sensitive color-changing material is a photosensitive color-changing material, 25%-75% of the polyvinyl chloride matrix, 25%-75% of stone powder, and 1%-45% of auxiliary agents, wherein the auxiliary agents are plasticizers, stabilizers, Titanium dioxide, ultraviolet absorbers, antioxidants, antiaging agents, antistatic agents, dispersants, fluorescent whitening agents, thickeners, pearl mica powder, antibacterial agents, bacteriostatic agents, organic and inorganic pigments, dyes One or more, photochromic material 0.1‰-40%.

[0044] This kind of optically variable floor can increase the aesthetics of the product according to the different requirements of customers, according to the change of the ultraviolet intensity of the day, for example: outdoor sports venues can display different colors or dividing lines in different sports venues under the same square.

Embodiment 3

[0045] Embodiment 3: When the inductive color-changing material is a photosensitive luminescent material or a light-absorbing luminescent material, the polyvinyl chloride matrix is ​​25%-75%, the stone powder is 25%-75%, and the auxiliary agent is 1%-45%, wherein the auxiliary agent is a plasticizer , Stabilizer, Titanium Dioxide, UV Absorber, Antioxidant, Antiaging Agent, Antistatic Agent, Dispersant, Fluorescent Whitening Agent, Thickener, Pearlescent Mica Powder, Antibacterial Agent, Antibacterial Agent, Organic Pigment and Inorganic Pigment 1. One or more of dyes, photosensitive luminescent material or light-absorbing luminescent material 0.1‰-40%.

[0046] The sensory color-changing material is a photosensitive luminescent floor, which can realize the functions of lighting at night and reminding the direction, and has an aesthetic effect, such as the direction and decoration of emergency passages or fire exits in public places at night.

Abstract

The invention relates to the field of decorative building materials, in particular to a PVC floor and a production process. By designing the corresponding raw material ratio and the corresponding process, the PVC floor can change correspondingly according to the temperature and the brightness of the environment. The PVC floor comprises the following components in percentage by mass: 20-80% of a polyvinyl chloride matrix, 20-80% of stone powder and 1-50% of an auxiliary agent, and 0.01-40% of an inductive color-changing material. The method sequentially comprises the following steps of measuredfeeding, hot mixing, cold mixing, double-screw extrusion, single-screw extrusive granulation, particle spreading, initial forming and UV surface treatment. According to the invention, the PVC floor material and the induction color-changing and light-emitting material can be fused with each other in a hot melting state at a proper temperature under a proper process condition; in addition, under the condition that the PVC floor material and the inductive color-changing and light-emitting material are in a mutually fused state, the independence performance of the PVC floor and the performance ofthe inductive color-changing and light-emitting material can be achieved.

Description

technical field [0001] The invention relates to the field of decorative building materials, in particular to a PVC floor and a production process. Background technique [0002] At present, PVC floor is a light-weight floor decoration material, which refers to the floor produced by polyvinyl chloride material, specifically refers to polyvinyl chloride and its copolymer resin as the main raw material, adding fillers, plasticizers, stabilizers, coloring, etc. Additives and other auxiliary ingredients, on the sheet-like continuous substrate, use the calendering or coating process, the floor produced by the basis or extrusion. PVC flooring has the characteristics of bright and beautiful appearance, good wear resistance, dirt resistance and good anti-skid performance. Moreover, PVC flooring has a wide range of raw materials and can be reused at the same time. It is a floor that is both practical and economical. [0003] But so far, for PVC flooring, the performance of its develo...
