preparation example Construction

[0032] A kind of preparation method of the flame retardant sealing agent that is used for substation of the present invention, comprises the steps:

[0033] Preparation of component A: take vinyl silicone resin, activated aluminum hydroxide and melamine according to the formula, put them into a vacuum kneader, and mix them under vacuum at 110-130°C to obtain the base material, which is ready to use after cooling; 100 parts of base material, add catalyst according to the formula, and stir evenly with a variable speed mixer to obtain component A;

[0034] Preparation of component B: Take vinyl silicone resin, hydrogen-containing silicone resin, inhibitor and tackifier from the formula, and slowly stir and mix with a variable speed mixer to obtain component B.

[0035] During the preparation of component A, the vacuum mixing time is 3.8-4.2h; the stirring speed is 1200-1700rpm, and the stirring time is 15-25min; during the preparation of component B, the slow stirring speed is 10...

Embodiment 1

[0038] A flame retardant plugging agent for substations of the present invention is composed of components A and B in a mass ratio of 5:1, and components A and B are formulated according to the following weight calculations:

[0039] A component:

[0040]

[0041] B component:

[0042]

[0043] A preparation method for a flame retardant sealing agent for a substation of the present embodiment, comprising the steps of:

[0044] Preparation of component A: add the vinyl silicone resin, activated aluminum hydroxide and melamine in parts by mass into a vacuum kneader, mix in a vacuum at 110-130°C for 4 hours, cool down and set aside; take 190 parts of the base material , 0.8 parts of chloroplatinic acid (platinum content 4000ppm), stirred for 20min under the condition of variable speed mixer 1500rpm to obtain A component;

[0045] Preparation of component B: slowly stir the vinyl silicone resin, hydrogen-containing silicone resin, ethynyl cyclohexanol and N-(β-aminoethyl)-...

Embodiment 2

[0047] A flame retardant plugging agent for substations of the present invention is composed of components A and B in a mass ratio of 5:1, and components A and B are formulated according to the following weight calculations:

[0048] A component:

[0049]

[0050] B component: same as embodiment 1

[0051] A preparation method of a flame retardant plugging agent used in a substation in this embodiment differs from the preparation method in Example 1 only in that the ratio of raw materials is different in the preparation process.

Abstract

The invention provides a flame-retardant blocking agent for a substation, and a preparation method and a use method thereof, the flame-retardant blocking agent comprises a component A and a componentB according to a mass ratio of 4-6: 1, the component A is prepared from the following components by weight: 100 parts of vinyl silicone resin, 75-110 parts of a flame-retardant filler and 0.1-6 partsof a platinum catalyst; and the component B is prepared from the following components in parts by weight: 20-60 parts of vinyl silicone resin, 40-80 parts of hydrogen-containing silicone resin, 0.5-5parts of a tackifier and 0.01-2 parts of an inhibitor. The flame-retardant blocking agent is a liquid before curing, has good fluidity and plasticity, has good toughness, excellent fire resistance, excellent flame retardance, excellent aging resistance and the like after curing, has a flame retardant grade reaching UL-94 V0 grade, has an excellent plugging effect on various complex working conditions and complex shapes, and is attractive and smooth in appearance.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a flame-retardant plugging agent for substations and a preparation method and application method thereof. Background technique [0002] In modern industrial production and social life, the substation plays a very important role. The safe operation of the substation and the fire protection system are one of the most critical links. With the development of the times and the progress of society, safety production has been raised to a higher level, and the traditional sealing materials mainly composed of "fireproof gypsum board, fireproof cement, fireproof bag (bag), fireproof coating, etc." have Many shortcomings, reliability, especially in terms of service life, maintainability, reusability, aesthetics, anti-rat bite, weather resistance, etc., the limitations of traditional fireproof materials are getting bigger and bigger, and there is a tendency to be gradually eli...
