Problems solved by technology

However, since PVC is a chlorine-containing hydrocarbon, polyvinyl chloride is a thermoplastic linear resin (its structural formula is [—CH2-CHCl]n) produced by addition polymerization of monomer vinyl chloride. Structural characteristics, plasticizers (generally DOP, DOA, DINP, etc.) must be added during processing. These added plasticizers contain different amounts of phenol, and long-term exposure will be harmful to the nervous system and urinary system of the human body. impact, especially children who directly touch the ground with their bodies, are particularly serious; in addition, PVC products have a pungent smell during p

Embodiment 1

[0053] Example 1: Processing of new TPU raw materials

[0054] Midsole material layer: TPU: CaCO 3 =20-30kg: 70-80kg.

[0055] Primer layer: TPU: CaCO 3 =32.5-42.5kg: 56.5-66.5kg.

[0056] refer to figure 1 and figure 2 , the wear-resistant layer 1, the printing layer 2 and the base layer 3 are respectively processed and cut into slices according to the production specifications, and passed the inspection, and several sheets are neatly stacked on the pallet for use. Among them, the wear-resistant layer 1 is a sheet made of TPU raw material through extrusion and casting equipment. According to the design requirements, a wear-resistant layer material with a thickness of 0.1-2.0mm can be processed; the printing layer 2 is TPU raw material through blow molding or stretching equipment. , process a printing layer film with a thickness of 0.05-1.0mm, and then print a color pattern through offset printing; the base layer 3 is divided into two layers, namely the middle bottom mat...

Embodiment 2

[0060] Example 2 TPU new material and recycled material processing

[0061] The basic process is the same as the above example, wherein the raw materials of the base layer are mixed in parts by weight: 50 parts of TPU new material + 50 parts of TPU recycled material to form 100 parts of TPU mixture, and the mixture is divided into two parts on average. The formula is:

[0062] Midsole material layer: 50 parts of TPU mixture + 122-132 parts of stone powder (CaCO 3 )

[0063] Bottom material layer: 50 parts of TPU mixture + 62-72 parts of stone powder (CaCO 3 )

[0064] The raw materials are mixed, mixed by high-speed mixing and mixing equipment, and pressed into small pieces that can be glued. Pressurization parameters: pressurize for 2 minutes for the first time, stop for 0.8 minutes in the middle, turn the material, and pressurize for 1 minute for the second time; thermal compound parameters: preheating temperature between 120-135°C, hot pressing after preheating, the pres...

Embodiment 3

[0065] Embodiment Three Processing of all TPU recycled materials

[0066] The basic process is the same as the above example, wherein the TPU raw materials in the base layer are all recycled materials, and the formula is as follows according to the parts by weight:

[0067] Midsole material layer: 50 parts of TPU recycled material + 105-110 parts of stone powder (CaCO 3 )

[0068] Bottom material layer: 50 parts of TPU recycled material + 56-61 parts of stone powder (CaCO 3 )

[0069] The raw materials are mixed, mixed by high-speed mixing and mixing equipment, and pressed into small pieces that can be glued. Pressurization parameters: pressurize for 2 minutes for the first time, stop for 0.8 minutes in the middle, turn the material, and pressurize for 1 minute for the second time; thermal compound parameters: preheating temperature between 120-135°C, hot pressing after preheating, the pressure is at Control at 0.60-0.80mpa, saturation temperature 135-140°C, heat press for...

Abstract

The invention provides a thermoplastic polyurethane floor tile and a producing technique thereof. The floor tile comprises a wearing layer, a printing layer and a base layer, which are compounded together from top to bottom in sequence to be integral, wherein the wearing layer is made of TPU sheets with the thickness of 0.1-2.0mm, the printing layer is made of TPU films with the thickness of 0.05-1.0mm and patterns on the surface, and the base layer is made of sheets mixed and rolled by TPU and rock flour. The producing technique is completed by the following steps: layered material processing, hot pressure laminating semi-finished products slotting and trimming, cleaning and packaging. The hot compounded floor tile of the invention produced by fully using the physical and chemical properties of the thermoplastic polyurethane has characteristics of high surface hardness, wearing resistance, skid resistance, no moisture absorption, no mould, good glossiness, abundant patterns, light weight, simple and convenient construction and recyclability.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a thermoplastic polyurethane floor tile and a production process thereof. Background technique [0002] Recently, with the advancement of composite materials and the improvement of processing technology, all kinds of plastic floor tiles have appeared, with light weight, convenient laying, surface wear resistance, thin thickness and high elasticity, etc., replacing some of the previous share of ceramic tiles and marble. , Widely used in public and temporary occasions. Most of the existing plastic floor tiles are made of PVC materials, and various patterns and textures are printed on the surface to meet people's different aesthetic needs. However, although the selection of PVC floor tiles reduces the content of heavy metals and harmful volatiles. However, since PVC is a chlorine-containing hydrocarbon, polyvinyl chloride is a thermoplastic linear resin (its structural formula is...
