Problems solved by technology

[0002] At present, the fireproof coatings for wires and cables mainly use solvent-based cable fireproof coatings for fire protection, but solvent-based cable fireproof coatings contain a large amount of volatile organic solvents, and there are obvious safety hazards during production and construction. There are mainly the following three disadvantages : First, solvent-based cable fireproof coatings are listed as dangerous goods during vehicle and ship transportation
Second, the volatility of toxic solvents will pollute the environment and cause harm to the human body
The third is the flammability of solvents, which brings danger to production, construction and storage.
However, some water-based cable fireproof coatings on the market have insufficient adhesion and contain halogen, which will damage the cable skin to a certain extent, such as
[0003] No. 200610053130.7 Chinese patent, its process is more complicated, the 52 degree chlorinated paraffin added in the components is halogen-containing elements

Embodiment 1

[0025] Pump 75kg of water and 200kg of elastic acrylic emulsion into a multifunctional mixer and mix them at a speed of about 200rpm. Add 100kg of aluminum hydroxide flame retardant, 25kg of melamine, 50kg of rutile titanium dioxide, 10kg of calcium carbonate, 20kg of dipentaerythritol and poly Ethylene wax 15kg, fully stirred for 3 hours, rotating speed 600rpm. Move the material to a horizontal closed sand mill for sanding, and sand while cooling. The barrel pressure in the sand mill is kept at about 0.1MPa. After sanding, move the material to a multifunctional mixer, and add it while stirring. Sodium polyacrylate 5kg, obtain environment-friendly cable fireproof coating after increasing the consistency. The physical and chemical performance indicators of the product are shown in Table 1

Embodiment 2

[0027] Pump 50kg of water and 150kg of elastic acrylic emulsion into a multifunctional mixer and mix them at a speed of about 200rpm. Add 80kg of magnesium hydroxide flame retardant, 30kg of melamine, 40kg of rutile titanium dioxide, 10kg of talcum powder, 15kg of dipentaerythritol and two Silicon oxide 10kg, fully stirred for 2.5 hours, rotating speed 600rpm. Move the material to a horizontal closed sand mill for sanding, and sand while cooling. The barrel pressure in the sand mill is kept at about 0.1MPa. After sanding, move the material to a multifunctional mixer, and add it while stirring. Polyethylene oxide 3kg, the environment-friendly cable fireproof coating can be obtained after increasing the consistency. The physical and chemical performance indicators of the product are shown in Table 1

Abstract

The invention relates to a manufacturing method of fireproof paint, in particular to environment-friendly cable fireproof paint and a manufacturing method thereof. The environment-friendly cable fireproof paint comprises the following initial raw materials in parts by weight: 1-50 parts of water, 10-90 parts of elastic acrylic based emulsion, 1-10 parts of stuffing, 10-90 parts of flame retardant,1-10 parts of melamine, 1-10 parts of rutile type titanium pigment, 1-10 parts of dipentaerythritol, 1-10 parts of thixotropic agent and 1-10 parts of thickening agent. The environment-friendly cablefireproof paint is water-based fireproof paint, has the advantages of no halogen, innocuity, no corrosion, safety, environmental protection, high-effective flame retardance, volume increase in case of fire, convenient construction and the like, radically eliminates the fire risks due to the solvent volatilization of solvent type paint in production and construction, and reduces the harm to peopleand the pollution to environment caused by harmful organic solvents.
