Description
Technical Field
The invention relates to the technical field of paving materials, in particular to a rubber and plastic flexible mute floor material and a preparation method thereof.
Background
Polyvinyl chloride is a cheap and well-processed general-purpose plastic, related products are commonly found in daily life, but the polyvinyl chloride has essential defects as plastic, such as low temperature brittleness, poor elasticity, poor impact resistance and easy permanent deformation, so that the properties of the polyvinyl chloride can be improved by other materials in reality, such as various plastics, rubber and additives. The polyvinyl chloride is modified by the rubber, so that the tendency of migration and precipitation of the plasticizer can be reduced, the calendering and extrusion process performance of the product can be improved, the flexibility, elasticity, wear resistance and pressure deformability of the product can be improved, and the dimensional stability and the stiffness of the extruded product can be facilitated. The rubber modification can also improve the oil resistance, the ageing resistance and the low temperature property, increase the stability of the product to ultraviolet radiation, further prolong the service life of the product and keep the advantages of the original PVC product, such as chemical resistance, heat resistance, flame retardance and insulativity.
The stone-plastic floor tile is a new type floor decoration material combining high-quality simulation printing and high-tech material compounding, the printing facing is protected by a high-molecular wear-resistant layer, the stone-plastic base material determining the key of whole thickness and performance is arranged below the printing facing layer, and various layer materials are processed and combined into a product which is beautiful, simulated, economical and durable through multiple procedures.
The traditional heterogeneous polyvinyl chloride floor tile can be further divided into a flexible soft board (such as LVT) and a non-flexible hard board (such as WPC and SPC), the main plastic is polyvinyl chloride, the hardness degree is usually controlled by a plasticizer, the higher the content of the plasticizer is, the softer the whole substrate is, but the toughness is poor, the accompanying disadvantages are that the size stability and the residual concavity performance are reduced, even other problems are caused by migration and precipitation of the plasticizer, although the size stability and the residual concavity performance of the hard board without the plasticizer are good, the requirement on the ground level is high due to insufficient laminating property, and if the floor is uneven, the floor tile cannot be installed or can generate sound when being trampled due to gaps.
Mineral powder filler in stone-plastic base material is mainly characterized by that it is cheap, stable and safe, and can be filled in a large volume to obtain required base material thickness, and the polyvinyl chloride plastic is mainly used for binding mineral powder to give soft property and can be easily processed into the required form, and the two portions of stone and plastic are mixed and combined by means of universal machine or extruder, and rolled into the sheet material with required thickness by means of roller, and is similar to a homogeneous flexible deformable ' soft stone ' structure, and the heterogeneous polyvinyl chloride floor tile is called ' heterogeneous ', and is actually a floor tile formed by combining several layers of different components of layer material, so that it is different from integral ' homogeneous transparent floor tile.
Paving floor materials, such as glue ground installation, floating installation, lock catch installation and the like, but the installation methods have great limitations, for example, the glue ground installation has high requirements on the quality of glue and is inconvenient to disassemble; in order to avoid directly sticking to the ground, the floating installation needs to additionally lay a bedding material firstly, and then sticks the ground material on the bedding material by glue, thereby increasing the construction cost; the lock catch installation has higher requirements on the shape of the product, and is not favorable for the beautiful design.
Disclosure of Invention
In order to overcome the defects and shortcomings in the prior art, the invention aims to provide the rubber-plastic flexible mute floor material and the preparation method thereof, the structure and the manufacturing process of the rubber-plastic flexible mute floor material are simplified, the rubber-plastic flexible mute floor material has the functions of flexibility, mute and low shrinkage, is convenient to assemble and disassemble and can be repeatedly used, can be completely recycled and reproduced in the future, and the burden on the environment is reduced.
