Description

Technical Field

[0001] The present invention relates to the field of garage industrial floor mats, and more specifically, to a garage industrial floor mat and a preparation method thereof. Background Art

[0002] In the fields of modern industrial and civil architecture, as an important place for vehicle parking, the performance of the garage floor materials is crucial. Garage industrial floor mats are floor materials designed specifically for the garage environment, and they must possess extremely high abrasion resistance, moisture resistance, skid resistance, and durability to ensure that problems such as ground water seepage, dampness return, cracking, or hollowing do not occur after long-term use.

[0003] Traditional garage floors mostly use ordinary floor materials, such as cement floors, ordinary floor tiles, etc. These materials have many problems in actual use: First of all, insufficient abrasion resistance is a major defect. Frequent driving and turning of vehicles cause serious wear to the ground, not only shortening the service life of the floor materials but also increasing the maintenance cost. Secondly, the skid resistance performance is poor. In a wet or oily environment, vehicles are prone to skidding, posing a safety hazard, which is particularly prominent in rainy and snowy weather or when vehicles leak oil. Moreover, the corrosion resistance is poor. Common substances such as oil stains, acids, and alkalis in the garage will erode the ground, causing it to change color, blister, or even peel off, affecting the overall beauty and service life of the garage. In addition, the construction process of traditional floor materials is cumbersome, requiring multiple processes, consuming a large amount of time and manpower, and prolonging the construction period. Also, some traditional materials will release harmful substances such as formaldehyde and benzene during production and use, posing a potential threat to the environment and human health, and not meeting the development trend of green environmental protection.

[0004] With the emergence of personalized garages, epoxy floor paints have begun to be used for underground garage floors. Although the problems of poor abrasion resistance and corrosion resistance have been solved, there are still disadvantages such as easy slipperiness, easy aging, and complex construction, and the abrasion resistance is difficult to meet the ultra-high requirement of FV≤1.5.

[0005] To solve the above problems, the present invention provides a garage industrial floor mat, which has good abrasion resistance, durability, and skid resistance; in addition, this industrial floor mat also has a high color fastness and can meet the requirements of existing customers for garage industrial floor mats. Summary of the Invention

[0006] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a garage industrial floor mat, which has good abrasion resistance, durability, and skid resistance; in addition, this industrial floor mat has a high color fastness and has a certain aesthetic property.

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0014] Further, the ultra-high molecular weight additive is an emulsion-modified PTFE micropowder, ultra-high molecular weight polyethylene, polytetrafluoroethylene micropowder or a polyester plasticizer.

[0015] Further, the high molecular weight resin is polyvinyl chloride resin.

[0016] Further, the high molecular weight plasticizer is diisononyl cyclohexane-1,2-dicarboxylate (DINCH).
