Phase-changing heat absorption expansive flame-retardant fireproof water-based paint and preparation method thereof

Abstract

The invention discloses phase-changing heat-absorption expansive flame-retardant fireproof water-based paint. The phase-changing heat absorption expansive flame-retardant fireproof water-based paint is prepared from the following components in parts by weight: 35 to 75 parts of polyethylene glycol phase-changing self-cross-linked acrylate film forming emulsion, 5 to 25 parts of galactose expansionflame-retardant system and 5 to 35 parts of expandable filler. The phase-changing energy-storage material such as the polyethylene glycol and the galactose are used for absorbing the potential heat in a fire environment to resist the temperature rising, the expansive flame-retardant system formed by the ammonium polyphosphate and galactose is used for resisting the combustion of the material, sothat the high-efficiency flame retardance and fire resistance are realized, and the phase-changing absorbed heat is vast, the cooling and fireproof effect is significant, and the phase-changing heat-absorption expansive flame-retardant fireproof water-based paint is suitable for the flame retardance and fire resistance of furniture, walls, steel structures, cars, ships and tunnels; and the paint is carbonized and expanded at 250 DEG C to form an expansive foam carbon layer, so that the heat and oxygen can be effectively insulated, the release of the combustible gas can be prevented, the low fire can be prevented from forming big fire, the fire occurrence probability can be reduced, and the fire loss can be reduced.

Description

technical field [0001] The invention belongs to the field of functional paint manufacturing, and in particular relates to a phase-change heat-absorbing expansion type flame-retardant and fire-resistant water-based paint and a preparation method thereof. Background technique [0002] Flame retardant and fire prevention are important issues related to the safety of people's lives and property. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. According to statistics from the Fire Department of the Ministry of Public Security, in 2015, a total of 338,000 fires were reported across the country, resulting in 1,742 deaths, 1,112 injuries, and direct property losses of 3.95 billion yuan. On May 25, 2015, a particularly serious fire accident occurred in Kangyuan Senior Apartment, Lushan County, Pingdingshan City, Henan Province, resulting in 39 deaths and 6 injuries. The fire area was 745.8 sq...

Problems solved by technology

[0013] Although the above research work has achieved some gratifying results, the existing intumescent flame-retardant coatings cannot suppress the rapid rise in temperature in the medium and low temperature range, and the fire prevention efficiency is not high. The existing phase change coatings have no flame-retardant and fire-proof effects. Low temperature phase change heat absorption, high temperature expansion carbon layer heat insulation protection phase change heat absorption expansion flame retardant coating is very necessary
