Embodiment 1

[0057] The flexible epoxy composite coil provided in this embodiment, such as figure 1 As shown, it includes a first resin layer 1 , a first reinforcing layer 2 , a second resin layer 3 , a second reinforcing layer 4 and a third resin layer 5 that are stacked in sequence from top to bottom.

[0058] In this example, the first reinforcing layer 2 is a glass fiber mesh cloth layer, and a glass fiber mesh cloth with a mesh size of 3×3 mm is selected, and the weight per square is 100g; the second reinforcing layer 4 is a flame-retardant polyester fiber cloth layer, with a thickness of is 1.2mm.

[0059] The raw material formula of the first resin layer 1 is as follows: 40 parts of light-cured epoxy acrylic resin L-6136, 10 parts of light-cured urethane acrylic resin FSP38569, 5 parts of toughening agent o-phthalic flexible unsaturated resin, 20 parts of thinner (two Propylene glycol diacrylate and glycidyl methacrylate compound diluent in mass ratio of 5:1), 3 parts of dispersant...

Embodiment 2

[0067] The flexible epoxy composite coil provided in this embodiment is different from Embodiment 1 in that the raw materials of the first resin layer 1 , the raw materials of the second resin layer 3 , the raw materials of the third resin layer 5 and the raw materials of the first reinforcing layer 2 Different materials:

[0068]In this example, the raw material formula of the first resin layer 1 is as follows: 20 parts of light-cured epoxy acrylic resin L-6135, 15 parts of light-cured urethane acrylic resin Unicryl R7496, 5 parts of toughener o-phthalic flexible unsaturated resin, 15 parts of parts of diluent (a compound diluent of acrylate glycerol derivatives and 1,2-epoxy-5-hexene in a mass ratio of 2:1), 3 parts of dispersant polyether-modified siloxane, 1 Parts of scratch-resistant agent nano-silica, 2 parts of chopped glass fiber with a length of 3mm, 3 parts of coupling agent KH-570 and 3 parts of photoinitiator 1173.

[0069] In this example, the raw material formul...

Abstract

The invention relates to an anti-corrosion flexible epoxy composite coiled material as well as a preparation method and application thereof, and the flexible epoxy composite coiled material comprises a first resin layer, a first reinforcing layer, a second resin layer, a second reinforcing layer and a third resin layer which are sequentially stacked, the first resin layer, the second resin layer and the third resin layer are respectively compounded by light-cured epoxy acrylic resin and light-cured polyurethane acrylic resin as main raw materials, and the light-cured epoxy acrylic resin is selected from aliphatic flexible long-chain modified epoxy acrylic resin; and the light-cured polyurethane acrylic resin is selected from aliphatic polyurethane acrylic resin with polyfunctionality. The three resin layers not only retain the inherent characteristics of epoxy resin, but also increase the advantages of acrylic resin and polyurethane resin, and meanwhile, the film layer is toughened from the molecular level to form a cross-linked network composite film layer structure reinforced in an elastomer; the composite resin system has weather resistance, flexibility and good mechanical strength at the same time.

Description

technical field [0001] The invention belongs to the technical field of polymer composite building materials, and particularly relates to an anti-corrosion flexible epoxy composite coil material and a preparation method and application thereof. Background technique [0002] Epoxy floor is a high-strength, wear-resistant polymer floor with the advantages of firm texture, good chemical resistance, good barrier performance, and low maintenance costs. It is a widely used polymer building material. According to the different characteristics of epoxy floor, it can be roughly divided into epoxy resin grinding stone floor, epoxy resin mortar floor, epoxy resin color sand pressed sand floor, epoxy resin flat coating type floor, epoxy resin self-leveling floor Ping, etc. At present, in addition to certain functionalities, such as wear resistance, anti-skid, anti-corrosion, etc., epoxy floors also have decorative effects. They have gradually developed into general-purpose industrial fl...
