Problems solved by technology

The surface layer of SPC plastic floor is composed of color film, wear-resistant layer and UV curing layer. The main material of color film and wear-resistant layer is PVC resin, but the heat resistance of PVC resin is poor; the UV curing layer is mainly composed of acrylic resin. General heat resistance, no anti-scald performance
Moreover, the general UV coating process on the surface of SPC plastic flooring is: 1 UV primer and 1 UV topcoat coating and curing, and the total UV coating amount is 13-15g / m 2 , under this coating amount, the UV coating can only form a cured layer of about 10um on the surface of the plastic floor after photocuring, which does not have good heat insulation and heat resistance properties
[0003] In daily life, it often happens that unextinguished cigarette butts fall to the floor surface. Since the maximum temperature of the cigarette butt can reach 800°C, the UV cured layer softens quickly under the burning of the cigarette butt, and then breakage occurs. At the same time The UV curing layer quickly transmits the temperature of the cigarette butt to the surface of the wear-resistant layer. Because the wear-resistant layer is made of PVC products, its heat transfer and heat resistance are not good, which will lead to softening and damage of the wear-resistant layer, resulting in the surface of the PVC polymer plastic floor Destruction occurs as a whole, and macular and even black spots are formed on the cigarette butt

Description

technical field [0001] The invention belongs to the technical field of plastic floor preparation, and in particular relates to an anti-scald ecological floor and a preparation method thereof. Background technique [0002] SPC plastic flooring has been accepted by more and more consumers because of its advantages such as zero formaldehyde, ultra-low shrinkage, waterproof, and convenient installation. The surface layer of SPC plastic floor is composed of color film, wear-resistant layer and UV curing layer. The main material of color film and wear-resistant layer is PVC resin, but the heat resistance of PVC resin is poor; the UV curing layer is mainly composed of acrylic resin. General heat resistance, no anti-scald performance. Moreover, the general UV coating process on the surface of SPC plastic flooring is: 1 UV primer and 1 UV topcoat coating and curing, and the total UV coating amount is 13-15g / m 2 , under this coating amount, the UV coating can only form a cured layer...
