Problems solved by technology

[0006] "Quick response, instant curing" is the unique technical advantage of spray polyurea, but it is also due to "rapid response, instant curing", which causes the coating to infiltrate and spread the underlying material (such as base treatment agent or concrete base) The process is short, which weakens the necessary and sufficient conditions for the adhesion with the underlying cladding material, so the bonding strength is difficult to meet the design requirements

Embodiment 1

[0046] High-strength high-speed iron waterproof material, the mass ratio of component A and component B is 1:1. A component raw materials (parts by weight): 100 parts of polyether DL-2000D, 5 parts of dioctyl phthalate, 14 parts of bis(4-isocyanate phenyl) methane, 10 parts of graphene / methanesulfonic acid solution, 6 parts of triphenyl phosphate. Component B raw materials (parts by weight): 66 parts of amino-terminated polyether, 30 parts of amine chain extender.

[0047] The amino-terminated polyether is obtained by uniformly mixing amino-terminated polyether T5000, amino-terminated polyether T3000 and amino-terminated polyether T403 in a mass ratio of 1:1:1.

[0048] The amine chain extender consists of 3,5-diethyl-2,4-toluenediamine, 4,4′-bis-sec-butylaminodiphenylmethane, 3,5-dimethylthio-2,4 Toluenediamine is obtained by stirring and mixing uniformly according to the mass ratio of 1:1:1.

[0049] Preparation of high-strength high-speed iron waterproof material:

Abstract

The invention discloses a high-strength high-speed iron waterproof material and a preparation method thereof. The high-strength high-speed iron waterproof material includes component A and component B, and component A is prepared from the following raw materials in parts by weight: polyether polyol 95‑105 parts, 1‑10 parts of plasticizer, 10‑20 parts of bis(4‑isocyanatophenyl) methane, 3‑30 parts of graphene / methanesulfonic acid solution, 5‑50 parts of additives; component B It is prepared from the following raw materials in parts by weight: 50-80 parts of amino-terminated polyether, and 20-40 parts of amine chain extender. The present invention optimizes the type and amount of amino-terminated polyether and amine chain extender suitable for high-strength high-speed iron waterproof materials through reasonable proportioning, and has excellent physical and mechanical properties, temperature resistance, weather resistance, chemical medium resistance and Outstanding wear resistance, convenient construction and high efficiency.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-strength high-iron waterproof material and a preparation method thereof. Background technique [0002] High-speed railway is referred to as "high-speed railway", which refers to the transformation of the original line (linearization, gauge standardization), so that the maximum operating speed is not less than 200 kilometers per hour, or a new "high-speed new line" is specially built to make the operating speed reach 200 kilometers per hour. A rail system with at least 250 kilometers per hour. [0003] There are three main types of waterproof materials: waterproof membranes, polyurethane waterproof materials, and new polymer cement-based waterproof materials. Waterproof materials are mainly used to prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquids, and moisture and steam in the air from intruding into buildings.
