preparation example Construction

[0043] F1: Diaminopolyethylene glycol modified hyperbranched polypyrrone, prepared by the following method:

[0044] (1) Preparation of naphthalene anhydride-capped hyperbranched polypyrrole solution

[0045] Add 1 mole of 1,3,5-tris(4-naphthyloxy-1,8-dioic acid) trimellitic anhydride and 2000ml m-cresol in a completely dry three-necked flask, stir under nitrogen protection, when the trianhydride After completely dissolving, add 0.5 mole of 3,3'-diaminobenzidine, stir at room temperature for 30 minutes, heat to 85°C, react for 3.5h, then react at 185°C for 4.5h; after the reaction, drop to At room temperature, naphthalene anhydride-capped hyperbranched polypyrrole solution is obtained;

[0046] (2) Preparation of diaminopolyethylene glycol modified hyperbranched polypyrrone

[0047] To the naphthalene anhydride-capped hyperbranched polypyrrole solution obtained in step (1), add 2 moles of diaminopolyethylene glycol with an average degree of polymerization of 226, stir at room ...

Embodiment 1

[0077] In parts by weight, add 35 parts of B1 and 3 parts of C1 into a gravity-free mixer, open the flying knife to avoid adhesion and prevent uneven mixing, the stirring time is 3 minutes, close the flying knife, and then add 5 parts of D1, 7 parts of E1, 8 parts of F1, 8 parts of G1, 5 parts of H1 and 5 parts of I1, continue to stir for 3 minutes, add 20 parts of A1; continue to stir for 2 minutes, measure and pack and discharge. After the powder is stirred evenly, the ratio of powder to water is 1:0.6, and it is ready to use according to the weight ratio.

Embodiment 2

[0079] In parts by weight, add 45 parts of B2 and 8 parts of C1 into the gravity-free mixer, open the flying knife to avoid adhesion and prevent uneven mixing, the stirring time is 3 minutes, close the flying knife, and then add 15 parts of D1, 15 parts of E1, 15 parts of F1, 15 parts of G1, 15 parts of H1 and 15 parts of I1, continue to stir for 3 minutes, add 50 parts of A2; continue to stir for 2 minutes, measure and pack and discharge. After the powder is stirred evenly, the ratio of powder to water is 1:1.5, and it is ready to use according to the weight ratio.

Abstract

The invention discloses a thick steel-structure fireproof radiation protective paint which consists of powder and water according to the weight ratio of (1:0.6)-(1:1.5), wherein the powder comprises the components of a fireproof filling material, a main bonding agent, an auxiliary bonding agent, wollastonite powder, mica powder, diamino polyethylene glycol modified hyperbranched polypyrrolone, polybenzimidazole modified meso-porous silicon, KH-560 and graphene oxide. The thick steel-structure fireproof radiation protective paint has the characteristics of being waterproof, anti-seepage, fireproof, impact resistant, simple in processing process, convenient to construct, non-toxic, harmless, long in service life, good in radiation protection performance and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a fireproof and radiation-proof coating for thick steel structures. Background technique [0002] With the development of industrialization, especially in the construction of large and medium-sized cities, steel structures have become a very important construction application material due to their fast and convenient construction advantages. As metal steel structures, they are mostly used in standard In factories, large stadiums, airports, bridges, three-dimensional garages and nuclear buildings. However, the fire resistance of steel structures is far inferior to that of brick-concrete structures. The critical temperature of steel is 540°C. When this temperature is reached, its bearing capacity will be reduced by about half. In a general fire, this temperature can be reached in about 15 minutes, leading to the collapse of the building. This chara...
