Example Embodiment

[0029] Example 1

[0030] Please refer to Table 1 for 5 fire retardant coating formulations of the present invention. First, according to formula 1 in Table 1, water-based ultra-thin intumescent steel structure fireproof and anticorrosion dual-function coating 1 was prepared. First add the water-based epoxy emulsion, water-based epoxy curing agent and self-crosslinking silicone acrylic emulsion into the mixing tank, after stirring evenly, add the fire prevention additive system (ammonium polyphosphate, melamine and pentaerythritol), fillers (sepiolite, titanium White powder, aluminum silicate fibers and expandable graphite flakes), additives (water-based defoamer and film-forming aid) and appropriate amount of water, after stirring for 20 minutes, put it into a ball mill to grind once, mix evenly, and then discharge into barrels. The properties of the fire retardant coating of the present invention obtained are shown in Example 1 of Table 2.

Abstract

The invention relates to fire-proof and corrosion-proof dual-function paint for a water-based ultrathin expansion steel structure and a preparation method thereof. Water-based epoxy emulsion and self-crosslinking silicone-acrylic emulsion are taken as film forming substances, high-polymerization ammonium polyphosphate, melamine and pentaerythritol are taken as fire-proof aid systems, titanium white, sepiolite and alumina silicate fiber which are added are taken as high temperature-resistant fillers, expansible graphite flake is particularly added and is taken as a fire-proof and corrosion-proof filler and a small number of film forming aids and water-based antifoaming agents are added simultaneously. The formed fire-proof paint has high expansion rate (about 15 times), fire endurance of up to 90 minutes (the coating thickness is 2 millimeters) and has high corrosion resistance. The preparation method of the paint is simple and environmentally-friendly and has low cost and wide application.

Description

technical field [0001] The invention belongs to the technical field of fireproof paint, and in particular relates to a water-based ultra-thin intumescent steel structure fireproof and anticorrosion dual-function fireproof paint and a preparation method thereof. Background technique [0002] There are two main types of existing steel structure fireproof coatings at home and abroad: non-intumescent fireproof coatings and intumescent fireproof coatings. The former has been gradually eliminated due to its poor fire resistance and corrosion resistance. There are many types of intumescent fireproof coatings for steel structures, which can be divided into three types according to the coating thickness: thick type, thin type and ultra-thin type; according to their material form, they can be divided into three types: water-based type, solvent type and powder type. Among them, water-based ultra-thin intumescent steel structure fireproof coating has good fireproof performance, and at t...
