Problems solved by technology

But it has the following disadvantages: 1. Poor toughness, easy to be brittle when impacted; 2. The brittleness of polyvinyl chloride is greatly affected by temperature. The lower limit of general PVC products is -15°C, and the lower limit of soft PVC is - 30℃
[0003] However, in the prior art, there are often poor compatibility between PVC and modified materials, which leads to insufficient adhesion between the two phases, and phenomena such as delamination and cracking are prone to occur during use, resulting in decreased or unstable performance of the blend, and will not produce good toughening effect

Embodiment 1

[0027] Weigh raw materials:

[0028] The PVC layer raw materials include: 80 parts of PVC resin, 55 parts of plasticizer DOP, 1 part of barium zinc stabilizer, and 1.0 part of dye.

[0029] The raw materials of the stabilization layer include: 80 parts of PVC resin, 55 parts of plasticizer DOP, 1 part of barium zinc stabilizer, and 28 parts of calcium carbonate.

[0030] The foam layer raw materials include: 80 parts of PVC resin, 55 parts of plasticizer DOP, 1 part of potassium zinc stabilizer, 2.5 parts of VC foaming agent, and 1.0 part of dye.

[0031] PVC-TPU adhesive sports floor preparation:

[0032] (1) Coating and sizing of the surface layer, mixing PVC layer raw materials: PVC resin, plasticizer, barium-zinc stabilizer, and dyes, melting at high temperature to form a melt glue, and coating at a temperature of 160°C and a vehicle speed of 10m / min Machine sizing, the PVC layer is obtained after the gel is set;

[0033] (2) Cloth base is bonded, the raw material of st...

Abstract

The invention relates to a PVC-TPU bonding sports floor and a preparation method thereof, comprising a foaming layer, a stabilizing layer, a PVC layer, and a TPU layer from bottom to top, and raw materials include PVC resin, a plasticizer, and a barium-zinc stabilizer , Potassium zinc stabilizer, VC foaming agent, dyes. Prepare a foam layer, a stable layer, and a PVC layer by melting first, and then double-bond the TPU layer containing polyvinyl chloride paste resin to the PVC layer to prepare a PVC-TPU bonding sports floor. Laying TPU makes the floor more elastic, the surface stain resistance effect is increased by more than 10 times, and the friction coefficient is increased by more than 100 times. The anti-ultraviolet effect and aging test have passed the certification and reached the national standard.

Description

technical field [0001] The invention relates to the technical field of sports floor production, in particular to a PVC-TPU bonding sports floor and a preparation method thereof. Background technique [0002] PVC is one of the common engineering plastics. PVC is thermoplastic, insoluble in water, gasoline and ethanol, swells or dissolves in ether, ketone, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons, has strong corrosion resistance and good dielectric properties, not only has quality Lightweight, but also has the characteristics of high strength, oil resistance, chemical resistance, etc., so it is often used in sports flooring and other materials. But it has the following disadvantages: 1. Poor toughness, easy to be brittle when impacted; 2. The brittleness of polyvinyl chloride is greatly affected by temperature. The lower limit of general PVC products is -15°C, and the lower limit of soft PVC is - 30°C. There are many toughening modifiers for PVC, which ca...
