Abstract

The invention relates to the technical field of a waterproof material and relates to a making method for a waterproof asphalt caulking factice of a building with fire resistance. The method comprisesthe following steps: taking the following raw materials in parts by weight: 40-65 parts of asphalt, 2-15 parts of chlorinated paraffin, 1-11 parts of styrene-butadiene-styrene segmented copolymer, 1-10 parts of styrene-isoprene-styrene segmented copolymer, 5-25 parts of calcium carbonate and 5-20 parts of iron oxide red; putting asphalt into a dosing reaction kettle, heating, rising temperature to110 DEG C and dewatering for 30min; heating to 180-220 DEG C, and then adding styrene-butadiene-styrene segmented copolymer and adding styrene-isoprene-styrene segmented copolymer, keeping high temperature, stirring and then grinding; cooling to 120-160 DEG C and then adding calcium carbonate and iron oxide red; uniformly stirring and then adding chlorinated paraffin; uniformly stirring and thenemptying and packaging, thereby acquiring the waterproof asphalt caulking factice of the building with fire resistance. The waterproof asphalt caulking factice of the building with fire resistance ischaracterized by high temperature flame retardant, low volatility, high construction degree, high caking property and high density.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a method for making building waterproof asphalt caulking ointment. Background technique [0002] Flame retardant refers to reducing the flammability of the material in the flame during the burning process of the material, slowing down the spread of the flame, and automatically extinguishing it in a short time after the flame is removed. The three conditions for combustion are: combustibles, sufficient temperature and oxygen. Asphalt is combustible, and its ignition temperature is 485°C. In practical applications, in order to meet the performance requirements of caulking ointment, in order to save costs during production, manufacturers often add 5%-20% light mineral oil, or even waste engine oil to increase its low-temperature flexibility to reduce elastomer modification. In this way, the ignition temperature of the caulking ointment can only reach 230-260°C, and it...
