Problems solved by technology
[0002] At present, 15% of the world's electricity consumption comes from cooling systems, causing a great energy crisis. Therefore, people have conducted a lot of research on how to reduce cooling energy consumption, and developed some materials that can achieve self-cooling to alleviate energy consumption. pressure
[0003] Materials with fireproof properties are widely used in daily life. However, the current fireproof materials do not have the function of self-cooling. After these fireproof materials are used for decoration, they will bring a greater burden to the power system when the temperature is high in summer.

[0042] The preparation method includes: adding phenol into the reaction vessel, adding part of formaldehyde, dicyandiamide and part of the catalyst at a speed of 800r / min to 1000r / min, then raising the temperature to 65°C to 75°C within 30min, and keeping it warm for 10min to 20min;
[0043] Raise the temperature to 80°C-100°C within 40min, keep it warm for 15min-25min, then cool down to 60°C-65°C, and then add the remaining amount of formaldehyde, the remaining amount of catalyst and water;
[0044] Raise the temperature to 80℃~100℃ within 20min, and maintain the viscosity at 3000mpa·s~5000mpa·s;
[0045] Add 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide and an ether solvent, heat to 110°C-130°C, keep it warm for 1.5h-2.5h, and then cool down to room temperature.
[0046] Within the range of preset mass parts, formaldehyde, phenol and dicyandiamide can react to generate dicyandiamide phenolic resin, and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) passes It...

Abstract
The invention relates to the field of materials, in particular to a fireproof composition and a preparation method and application thereof. The invention provides a fireproof composition which is a liquid dispersion system comprising the following components in parts by mass: 18-35 parts of modified phenolic resin, 0.5-1.2 parts of polyurethane, 0.5-1.2 parts of fluorinated polyurethane, 5-13 parts of heat-conducting filler and a flame retardant. The surface of a prepared fireproof composition membrane reaches a super-hydrophobic state, the porosity of the membrane is increased, the moisture transfer rate of the micro-porous membrane is increased, and evaporation and release of moisture are accelerated, so that the air permeability of the fireproof composition membrane is improved, a fireproof composition material can easily transfer heat through airflow, a self-cooling function in a high-temperature environment is realized, and the energy consumption is effectively reduced; and whilethe self-cooling function is achieved, the good flame retardant property of the fireproof composition is maintained, and the B1-level requirement can be met.
