Problems solved by technology

[0003] When the substrate of traditional waterproof materials is bonded to the adhesive layer, due to the weak bonding between the substrate and the adhesive layer, there will be delamination between the substrate and the adhesive layer, and water will seep through the bond. The agent layer flows into the joint between the adhesive layer and the substrate, and then flows out from the side of the substrate, resulting in unsatisfactory waterproof performance of the waterproof material

preparation example Construction

[0047] like figure 1 As shown, the preparation method of the above-mentioned waterproof material in one embodiment includes the following steps:

[0048] S110, providing a polymer resin substrate.

[0049] In this embodiment, the material of the polymer resin substrate is high-density polyethylene resin. High-density polyethylene resin has excellent physical and mechanical properties, which can meet the requirements of construction engineering for the puncture resistance of waterproof materials. In addition, HDPE resins are relatively low cost and easy to prepare. It can be understood that the polymer resin substrate can also be an ethylene-propylene rubber substrate or an ethylene-vinyl acetate copolymer substrate.

[0050] The thickness of the polymer resin base material may be 0.1mm-1.2mm. Of course, in other embodiments, the thickness of the polymer resin substrate can also be other values, and the thickness of the polymer resin substrate can be adjusted according to a...

Embodiment 1

[0074] A polymer resin substrate with a thickness of 0.5mm is provided. The material of the polymer resin substrate is high-density polyethylene resin.

[0075] Coat 6101 epoxy resin with a thickness of 0.1 μm on the polymer resin substrate to form an epoxy resin layer.

[0076]At 180°C, add titanium dioxide, antioxidant 1010, No. 5 white oil and calcined diatomite into the molten amorphous α-olefin copolymer. Stir evenly for 2 hours at a speed of 60 rpm to obtain a melt. Next, add ethylene-vinyl acetate copolymer into the molten liquid, and then stir for 5 minutes until completely melted to obtain an adhesive. Coat the adhesive on the epoxy resin layer while it is hot, and form an adhesive layer with a thickness of 0.1mm after cooling. Among them, the mass ratio of amorphous α-olefin copolymer, ethylene-vinyl acetate copolymer, titanium dioxide, antioxidant 1010, No. 5 white oil and calcined diatomite is 53:34.6:0.2:0.2:10:2 .

Embodiment 2

[0081] A polymer resin substrate with a thickness of 0.1mm is provided. The material of the polymer resin substrate is ethylene propylene rubber.

[0082] Coat 634 epoxy resin with a thickness of 0.15 μm on the polymer resin substrate to form an epoxy resin layer.

[0083] At 170°C, add titanium dioxide, antioxidant 1010, No. 5 white oil and calcined diatomaceous earth into the molten amorphous α-olefin copolymer. Stir uniformly for 3 hours at a rotational speed of 60 rpm to obtain a molten liquid. Next, ethylene-vinyl acetate copolymer was added into the molten liquid, followed by stirring for 7 minutes until it was completely melted to obtain an adhesive. Coat the adhesive on the epoxy resin layer while it is hot, and form an adhesive layer with a thickness of 1.5mm after cooling. Among them, the mass ratio of amorphous α-olefin copolymer, ethylene-vinyl acetate copolymer, titanium dioxide, antioxidant 1010, No. 5 white oil and calcined diatomite is 43.8:43.8:0.2:0.2:10:2...

Abstract

The invention relates to a waterproof material. The waterproof material comprises a macromolecule resin substrate, an epoxy resin layer, a binding agent layer and a sand layer which are sequentially overlapped with one another, wherein the binding agent layer comprises the following components in parts by weight: 20-70 parts of an amorphous-state a-olefin copolymer, 20-50 parts of an ethylene-vinyl acetate copolymer, 0.2-5 parts of titanium dioxide, 0.1-1 part of an antioxygen 1010, 5-20 parts of 5# white oil and 1-5 parts of calcined diatomite. According to the waterproof material, the epoxy resin layer is arranged between the macromolecule resin substrate and the binding agent layer and is taken as a transition layer to firmly binding the macromolecule resin substrate with the binding agent layer together, so that the connection among the layers of whole waterproof materials is firm, the water infiltration can be prevented, and the waterproof performance is good. Besides, the invention further provides a preparation method of the waterproof material.

Description

technical field [0001] The invention relates to a building material, in particular to a waterproof material. Background technique [0002] The waterproof material has the characteristics of low-temperature flexibility, self-healing and good bonding performance. It can be constructed at room temperature, the construction speed is fast, and it meets environmental protection requirements. Especially without hot-melt construction, avoiding the worry of fire. Waterproof materials have good low temperature resistance, and are suitable for waterproofing, moisture-proofing and sealing of roofs, basements, interiors, municipal engineering, reservoirs, swimming pools, subways and tunnels of industrial and civil buildings. It is especially suitable for waterproof and anti-corrosion projects such as military facilities that require cold construction and petroleum depots, chemical plants, textile mills, grain depots where open flames are not suitable. [0003] When the substrate of tra...
