Embodiment 1

[0019] A method for prolonging the storage time of fluororubber glue, comprising the steps of:

[0020] (1) Press the mixed fluorine rubber material into a small rubber block with a thickness of 3mm and a size of 400×400mm and put it into the mixing tank;

[0021] (2) Add ethyl acetate, the total amount is: fluorine rubber compound: ethyl acetate = 1:3, ethyl acetate is first added to 60% of the total amount, and stirred for 40 minutes;

[0022] (3) Add the remaining ethyl acetate and stir for 4 hours;

[0023] (4) Add methanol and continue to stir for 10 minutes. The amount of methanol added is: fluorine rubber compound: methanol = 1:2.

Embodiment 2

[0025] A method for prolonging the storage time of fluororubber glue, comprising the steps of:

[0026] (1) Press the mixed fluorine rubber material into a small rubber block with a thickness of 2mm and a size of 300×400mm and put it into the mixing tank;

[0027] (2) Add ethyl acetate, the total amount is: fluorine rubber compound: ethyl acetate = 1:4, ethyl acetate is first added to 60% of the total amount, and stirred for 40 minutes;

[0028] (3) Add the remaining ethyl acetate and stir for 7 hours;

[0029] (4) Add methanol and continue to stir for 8 minutes. The amount of methanol added is: fluorine rubber compound: methanol = 1:1.

Embodiment 3

[0031] A method for prolonging the storage time of fluororubber glue, comprising the steps of:

[0032] (1) Press the mixed fluorine rubber material into a small rubber block with a thickness of 2mm and a size of 200×200mm and put it into the mixing tank;

[0033] (2) Add ethyl acetate, the total amount is: fluorine rubber compound: ethyl acetate = 1:5, ethyl acetate is first added to 60% of the total amount, and stirred for 40 minutes;

[0034] (3) Add the remaining ethyl acetate and stir for 5 hours;

[0035] (4) Add methanol and continue to stir for 6 minutes. The amount of methanol added is: fluorine rubber compound: methanol = 1:1.5.

Abstract

The invention relates to preparation of fluororubber, in particular to a method for prolonging storage time of fluororubber paste. The method comprises the steps as follows: (1), a mixed fluororubber compound is pressed into small rubber bricks with the thicknesses of 2-3 mm and the sizes not larger than 400*400 mm, and the rubber bricks are added into an agitator tank; (2), ethyl acetate is added, the total adding amount is as follows: the ratio of the fluororubber compound to ethyl acetate is 1:(3-5), and 60% of a total adding amount of ethyl acetate is added firstly and stirred; (3), the residual ethyl acetate is added, and the stirring time is longer than 4 hours; and (4), methanol is added, stirring is performed continuously for 6-10 min, and the adding amount of the methanol is as follows: the ratio of the fluororubber compound to methanol is 1:(1-2). The method for prolonging the storage time of the fluororubber paste is reasonable in design and fundamentally solves the problem that the fluororubber paste gels easily.

Description

technical field [0001] The invention relates to the preparation of fluororubber, in particular to a method for prolonging the storage time of fluororubber glue. Background technique [0002] Fluorine rubber cloth has excellent corrosion resistance, and its stability to organic solvents, concentrated acids, high-concentration hydrogen peroxide and other oxidants is superior to other rubbers, especially under high temperature conditions, which other rubber materials cannot achieve. Protective performance is increasingly widely used in military and civilian markets. [0003] At present, the fluororubber tape produced by the coating process usually needs to mix the kneaded fluororubber and ethyl acetate in a certain proportion. The steps are: 1. Press the mixed fluororubber rubber into a small rubber block with a thickness of 2-3mm and no more than 400×400mm and put it into the mixing tank; 2. The ratio of fluororubber compounded rubber to ethyl acetate 1:5~8; add 40% of the t...
