Embodiment 1

[0027] (1) Preparation of nano flame retardant:

[0028] Add each flame retardant component to water that is 5 times the total weight of each flame retardant component, then add surface modifier, heat to 60 o After C, adjust the pH value of the system to 7.0 with dilute sulfuric acid, react for 3 hours and cool to obtain a nano-flame retardant sol containing aluminum hydroxide, that is, a nano-flame retardant. The selection and dosage of each flame retardant component and surface modifier are shown in Table 1.

[0029] (2) Preparation of fire retardant coating:

[0030] According to the filler and additive components selected in Table 2-3, and according to the dosage of each component in the formula in Table 4, first add the paint base to the mixing tank, stir evenly, and then add nano flame retardant and flame retardant synergist , fillers, additives and water, after stirring for 20 minutes, add them to the ball mill and grind them. After mixing evenly, use a scraper finene...

Embodiment 2

[0033] (1) Preparation of nano flame retardant:

[0034] Add each flame retardant component to water that is 6 times the total weight of each flame retardant component, then add surface modifier, heat to 50 o After C, adjust the pH value of the system to 6.0 with dilute sulfuric acid, react for 5 hours and cool to obtain a nano-flame retardant sol containing aluminum hydroxide, that is, a nano-flame retardant. The selection and dosage of each flame retardant component and surface modifier are shown in Table 1.

[0035] (2) Preparation of fire retardant coating:

[0036] According to the filler and additive components selected in Table 2-3, and according to the dosage of each component in the formula in Table 4, first add the coating matrix to the mixing tank, after stirring evenly, add nano-flame retardant and flame retardant synergist , fillers, additives and water, after stirring for 20 minutes, add them to the ball mill and grind them. After mixing evenly, use a scraper f...

Embodiment 3

[0039] (1) Preparation of nano flame retardant:

[0040] Add each flame retardant component to water that is 10 times the total weight of each flame retardant component, then add surface modifier, heat to 30 o After C, adjust the pH value of the system to 5.5 with dilute sulfuric acid, react for 0.5 hours and cool to obtain a nano-flame retardant sol containing aluminum hydroxide, that is, a nano-flame retardant. The selection and dosage of each flame retardant component and surface modifier are shown in Table 1.

[0041] (2) Preparation of fire retardant coating:

[0042] According to the filler and additive components selected in Table 2-3, and according to the dosage of each component in the formula in Table 4, first add the coating matrix to the mixing tank, after stirring evenly, add nano-flame retardant and flame retardant synergist , fillers, additives and water, after stirring for 20 minutes, add them to the ball mill and grind them.

Abstract

The invention relates to a water-based expansive type nano fireproof coating for a cable and a preparation method of the water-based expansive type nano fireproof coating. The water-based expansive type nano fireproof coating for the cable is characterized by comprising the following components in parts by weight: 20-40 parts of a coating base body, 15-45 parts of a nano flame retardant, 2-10 parts of a flame retardant synergist, 5-10 parts of a filler, 1-5 parts of an assistant and 10-30 parts of water, wherein the nano flame retardant is obtained by nano-crystallizing the flame retardant which comprises soluble aluminum salt, a charring catalyst, a charring agent and a foamer, and the flame retardant synergist is biomass ash of a power plant. As the components of the water-based expansive type nano fireproof coating are good in compatibility, the water-based expansive type nano fireproof coating is good in buckling resistance, humidity resistance, oil resistance and water resistance, excellent in flame retardance and low in charring height.

Description

technical field [0001] The invention relates to the field of fireproof coatings, in particular to a new water-based expandable nanometer fireproof coating for cables and a preparation method thereof. Background technique [0002] Wire and cable are important materials for electric power industry. With the rapid development of my country's economy, the energy industry as a basic industry and the communication industry as a high-tech industry have developed rapidly. The application of large-load and ultra-high-voltage power transmission technology is becoming more and more common. The fire hazard of wire and cable is becoming more and more prominent. Our country began to study cable fireproof coatings in the mid-1970s. It was developed on the basis of decorative fireproof coatings combined with its own requirements. Due to the thick coating of non-intumescent fire retardant coating. It is difficult to meet the bending requirements of cables. Therefore, the cable fireproof co...
