Problems solved by technology

The anti-corrosion floor has the characteristics of high interface bonding strength, medium permeability resistance and strong chemical corrosion resistance. Defects such as short life
[0007] The Chinese patent with the authorized announcement number CN 101705744B discloses a floor material, which is formed by a polyurethane synthetic leather layer, a glass fiber cloth layer bonded to the polyurethane synthetic leather layer, and coating the floor paint on the surface of the glass fiber cloth layer. This floor material has the advantages of wear resistance and oil resistance, but because the base fabric is polyurethane artificial leather, the base fabric material is easily hydrolyzed, and the coating system used in this material has no specific design for anti-corrosion function , so the material has poor water resistance and corrosion resistance
[0008] The Chinese patent with the authorized notification number CN 102102302A discloses a flexible veneer material composited with epoxy and PVC. The PVC layer is bonded to the bottom surface of the glass fiber cloth layer, and the surface of the glass fiber cloth is coated with an epoxy coating, but Due to the use of PVC as the bottom material, it has poor compression resistance, tensile resistance, chemical resistance, flame retardancy and other properties

Abstract

The invention discloses a preparation method for an anti-corrosion type fiber enhanced epoxy resin composite floor material. The method comprises the following steps: (1) first epoxy resin paint is coated on a support material layer, and is cured for the first time to obtain a first surface layer; (2) second epoxy resin paint is coated on the first surface layer, is compounded with a fiber fabric, and is cured for the second time to obtain an intermediate layer; and (3) after the surface is polished, the intermediate layer is coated with third epoxy resin paint; and a second surface layer is obtained through the curing for the third time, and is secondarily treated to obtain the anti-corrosion type fiber enhanced epoxy resin composite floor material. According to the anti-corrosion type fiber enhanced epoxy resin composite floor material and the preparation method thereof, the epoxy resin floor material with excellent corrosion resistance and good mechanical performance is prepared, and is laid on the floor when being needed to use, so that the problems of long construction period, weak construction environment and instable curing performance due to room-temperature curing in traditional anti-corrosive terrace paint systems, such as epoxy resin terrace, ethylene terrace and the like are avoided.

Description

technical field [0001] The invention relates to the field of epoxy resin composite materials, in particular to an anti-corrosion fiber-reinforced epoxy resin composite floor material and a preparation method thereof. Background technique [0002] In addition to being damaged by heavy loads, heavy impacts, scratches on steel wheels, etc., the floors of workshops and warehouses in chemical, electroplating, battery, petroleum, pharmaceutical, and smelting industries are also often damaged by acids, alkalis, salts, oils, and water. Ordinary concrete or cement floors are often difficult to withstand the erosion of liquids, so ground cracks and pulverization often occur during use. After a period of use, cracks appear, and the liquid penetrates into the ground quickly and directly corrodes The foundation of the building causes the buildings and structures to sink, which affects the use of the ground. In severe cases, even the underground structure will be corroded, causing ground ...
