Embodiment Construction
[0031] In order to further explain the technical scheme of the present invention, the present invention will be described in detail below through specific examples.
[0032] The invention relates to a high temperature-resistant foamed bead tire, comprising an inner core formed by heat-resistant elastomer foamed beads and a preformed tire tread, and the density of the foamed bead material is 0.10-0.45g / cm 3 , the linear shrinkage rate at 80°C is ≤1.5%, and the compression set at 80°C is ≤40%. The temperature-resistant elastomer foam beads have a cross-linked molecular chain structure, and the material of the tire table is selected from polyurethane One or more of rubber, natural rubber composite rubber, styrene-based rubber, butyl rubber, and polyolefin rubber.
[0033] Specifically, the temperature-resistant elastomer foam beads may be polyurethane foam beads. The inner core is made of heat-resistant elastomer foamed beads through water vapor molding, UV light irradiation m...

Abstract
The invention discloses a high-temperature-resistant foaming bead tire, a preparation method thereof and a foaming bead preparation method. The high-temperature-resistant foaming bead tire comprises an inner core formed by temperature-resistant elastic foaming beads and a preformed tire tread, the density of a foaming bead material is 0.10-0.45g / cm<3>, the linear shrinkage of the foaming bead material at the temperature of 80 DEG C is smaller than or equal to 1.5%, compressive permanent deformation of the of the foaming bead material at the temperature of 80 DEG C is smaller than or equal to 40%, the temperature-resistant elastic foaming beads has a cross-linked molecular chain structure, and materials of the tire tread are selected from one or more of polyurethane rubber, natural composite rubber, styrene rubber, butyl rubber and polyolefin rubber. According to the foaming bead tire, high-temperature resistance of the foaming bead tire is improved, and applicability of the foaming bead tire is ensured.
Description
technical field [0001] The invention relates to the field of foamed tires, in particular to a high temperature-resistant foamed bead tire, a preparation method and a preparation method of the foamed bead. Background technique [0002] Foam tires have the advantages of being free from inflation and maintenance, and have attracted widespread attention. PU foam materials have been used in bicycles, inner tubes of low-speed tires on construction sites, etc. However, PU has poor water resistance, poor tear performance, and poor aging performance, so it is obviously used in tires. [0003] Thermoplastic polyurethane (TPU) has many advantages such as high wear resistance, high elasticity, fatigue resistance, and chemical corrosion resistance. The molded body of TPU foamed beads is also used to prepare foamed tires. For example, the applicant applied for and obtained a Chinese authorized invention patent on October 28, 2014. Its patent number is CN201410589416.1, which clearly dis...
