Problems solved by technology

The above-mentioned lining materials have different defects in terms of wear resistance, impact resistance, installation firmness, and cost. For example, cast stone plates and calendered microcrystalline plates have good wear resistance, but poor impact resistance. Easily shattered under impact
Only the fixing method of pasting is adopted, and it is easy to fall off; the wear resistance of cement-based wear-resistant mortar and polymer board needs to be improved, and is not suitable for structures with large wear such as ore bins and pellet bins; the wear resistance and wear resistance of wear-resistant steel plates Good impact toughness, but expensive
[0003] In addition, some people have proposed to use epoxy resin and fly ash composite materials to make panels, but the wear resistance and impact resistance are poor, so it is not suitable for wear-resistant prefabricated panels.

Embodiment 1

[0036] An epoxy-based wear-resistant prefabricated board, the raw material components of which are measured in parts by mass are as follows:

[0037] 30 parts of epoxy resin component, composed of 24 parts of E51 epoxy resin and 6 parts of reactive diluent AGE;

[0038] 12 parts of epoxy curing agent, composed of 3 parts of aromatic amine and 9 parts of amino-terminated polyether;

[0039] 200 parts of aggregate components, composed of 50 parts of fly ash, 50 parts of quartz sand and 100 parts of granite;

[0040] 5 parts of chopped fibers are indented steel fibers with a length of 30 mm and a diameter of 0.8 mm.

[0041] Stir the epoxy resin component, epoxy curing agent and aggregate component separately first, then mix the epoxy resin component and epoxy curing agent evenly, add the aggregate component and chopped fibers while stirring, Stirring was continued for another 3 minutes. Pour the stirred mixture into the mold, which can be self-flowing and densely formed witho...

Embodiment 2

[0043] 40 parts of epoxy resin components, all of which are E44 epoxy resin;

[0044] 15 parts of epoxy curing agent, all organic acid anhydrides, the molecular weight of the organic acid anhydride is between 180-200, and the molecular structure contains a benzene ring;

[0045] 180 parts of aggregate components, composed of 50 parts of fly ash, 50 parts of river sand and 80 parts of corundum;

[0046] 30 parts of chopped fiber, composed of 20 parts of indented steel fiber and 10 parts of glass fiber.

[0047] Mix the epoxy resin component and the epoxy curing agent evenly and heat to 150° C., add the aggregate component and chopped fibers while stirring, and continue stirring for 3 minutes. Pour the stirred mixture into the mold, vibrate and compact, and then solidify at 150°C for 8 hours before demoulding. A high temperature resistant (200°C) wear-resistant prefabricated board can be prepared, and because a large amount of chopped fiber is added , this kind of wear-resista...

Embodiment 3

[0049] 35 parts of epoxy resin components, consisting of 30 parts of E51 epoxy resin and 5 parts of reactive diluent BGE;

[0050] 10 parts of epoxy curing agent, which is an aliphatic amine with an amine value between 490-500;

[0051] 600 parts of aggregate components, composed of 150 parts of slag powder, 200 parts of river sand and 250 parts of limestone;

[0052] Chopped fiber component 0 parts.

[0053] The manufacturing method is the same as in Example 1, and because a large amount of aggregate components are added, the overall cost of this wear-resistant plate is lower compared with other examples.

Abstract

The invention discloses an ultra-wearproof epoxy precast slab and an installation method thereof, wherein, material components of the precast slab based on parts by mass are as follows: 30-40 parts of epoxy resin component, 8-15 parts of epoxy hardener, 0-600 parts of aggregate component and 0-60 parts of chopped fiber. According to the invention, the precast slab has the advantages of excellent wear performance and impact resistance, long service life and corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an epoxy base wear-resistant prefabricated board and an installation method thereof. Background technique [0002] In metallurgy, coal, electric power, chemical industry, building materials and other industries, there are a large number of structures such as storage bins, hoppers, and discharge chutes. In order to protect the surface of these structures from the wear of materials and ensure the service life of the structures, according to the standard GB 50077 " Code for Design of Reinforced Concrete Silo" and GB50583 "Code for Design of Building Structure of Coal Preparation Plant" stipulate that a wear-resistant protective layer should be installed on the inner surface of these structures. The wear-resistant linings currently in use mainly include cast stone plates, calendered microcrystalline plates, cement-based wear-resistant mortars, polymer plates, and wear-resi...
