Embodiment 1

[0017] Weigh 1000 grams of silicone rubber, 150 grams of γ-mercaptopropyl trimethoxysilane, 200 grams of diethylene glycol monobutyl ether adipate, 100 grams of dicumyl peroxide, N-(1,3-dimethyl Base) butyl-N'-phenyl-p-phenylenediamine 100 grams, magnesium hydroxide 150 grams, carbon black 100 grams and 7-benzyloxy-4,5-dihydro-2H-[1,2,4] - 250 grams of triazol[4,3-a] quinolin-1-one;

[0018] The temperature of the front roll of the two-roll mill is controlled at 115°C, and the temperature of the rear roll is controlled at 105°C. The above materials are added to the two-roll mill one by one, passed through thinly for 3 times, then left for 5 hours, and then transferred to the QLB- Sheets are pressed in a D400X400X2 flat vulcanizer, the temperature of the plate vulcanizer is 130°C, the molding pressure is 1Mpa, and the molding time is 15 minutes.

Embodiment 2

[0020] Antifungal rubber was prepared in the same manner as in Example 1, except that 7-benzyloxy-4,5-dihydro-2H-[1,2,4]-triazole[4,3-a was not used ] and quinolin-1-one.

[0022] Performance Testing

[0023] (1) ASTM D412-1998 (2002) to measure the tensile strength of rubber;

[0024] (2) HG / T4301-2012 to determine the mold resistance of rubber.

[0025] result

[0026] The sample of Example 1: the tensile strength is 16.1Mpa, the anti-mildew grade is the first grade, and no mildew spots appear;

[0027] The sample of Example 2: the tensile strength is 12.9Mpa, the anti-mildew rating is three, and mildew spots appear.

[0028] It can be seen from the above results that after adding the anti-mold agent, the strength and anti-mold performance of the rubber are significantly enhanced, and comparing the results before and after the addition, the difference is statistically significant (P<0.05).
