Normal-temperature ice and preparation method thereof

Abstract

The invention discloses normal-temperature ice which is prepared from a component A and a component B. The component A includes following components in parts by weight: 90-100 parts of polyurea; the component B includes, in parts by weight: 90 to 100 parts of polyurethane prepolymer, 0.1 to 5 parts of delustering agent, 0.1 to 5 parts of lubricating agent, 0.1 to 3 parts of defoaming agent, 0.1 to3 parts of toner and 0.1 to 3 parts of dispersing agent; wherein the weight ratio of the component A raw material to the component B raw material is 1:1-1:5. The normal-temperature ice is simple in preparation mode, wherein a normal-temperature ice layer can be laid after the two components are mixed and cured, the construction difficulty is greatly reduced, the laying process and the curing process can be completed at the normal temperature, and high-temperature treatment and complex equipment operation are not needed. A feasible scheme is provided for on-site direct construction, more practical scenes are achieved, and the integrally-formed skating rink is more durable and attractive.

Description

technical field [0001] The invention relates to the technical field of normal-temperature ice, in particular to a normal-temperature ice and a preparation method thereof. Background technique [0002] Ice sports are relatively weak sports in our country. Due to the climate problem in our country, ice sports are very regional in the north and south of our country. To develop ice sports, it is necessary to increase the number of ice and snow sports grounds and increase the number of people learning ice sports. Existing simulated ice products on the market are: (U.S. Patent No. US6139438, US5837343) produced by Super Ice International Corp. of the United States; Japanese Mitsubishi resin Astro (Astro) company and Spanish artificial turf and landscaping company (International Patent Application No. PCT / ES / 2005 / 000685) developed and produced by (Artificial Grass&Landscaping inc.), and a simulated ice board with Chinese Patent No. CN201710630066.2. [0003] But above-mentioned e...

AI Technical Summary

Problems solved by technology

However, this type of existing product has the following defects: since the simulated ice surface is spliced ​​by blocks, there will inevitably be splicing marks, and the assembly system will inevitably produce assembly deviations, and changes in the external temperature will also cause large or small seams. Small deformation; the deviation of flatness is large, and the deviation that can be achieved in construction is generally ±5%. It is flat, the installation procedure is relatively complicated, and professional technicians are required to install and adjust special equipment; before use, it needs to be polished with professional equipment, and the surface is lubricated with lubricant, and the timeliness of use is poor; it needs to use special equipment on a regular basis. Maintenance and maintenance have certain construction difficulties, and the maintenance cycle is short, generally 1-2 times a week; the effective service life is short, and the thickness of the plate with a thickness of 30mm is generally 10 years on both sides; the initial investment and later maintenance costs are relatively high. high

[0004] Traditional ice and snow stadiums use real ice, which requires a lot of capital costs, professional ice-making personnel, professional ice-making equipment, large power consumption, and high maintenance costs. Due to the high cost and high professionalism required At present, there are very few real ice sports venues in the country
