Embodiment Construction

[0009] The specific implementation manners of the present invention will be further described below.

[0010] Represented by rubber compound, the technical solution to improve the anti-mold performance of rubber compound is: increasing the polarity of rubber can inhibit the growth of mold and improve the anti-mold performance of rubber. Therefore, according to the requirements of anti-mold, it is necessary to choose an appropriate type of anti-mold The mold agent is added to the rubber compound. The types of antifungal agents suitable for rubber products are: 5,6-dichlorobenzoxazolone (trade name: antifungal agent O), benzoimidazole methyl carbamate (trade name: antifungal agent BCM), 75 No. antifungal agent, YL-4 composite antifungal agent. The specific implementation plan is as follows:

[0011] 1) Raw rubber masterbatch: add fillers and additives (plasticizers, anti-aging agents) to the raw rubber, and then masterbatch (35-45) min;

[0012] 2) Filtration: Carry out two-l...

Abstract

The invention belongs to the aeronautical material manufacturing technique and relates to a method for improving the fungus-proof performance of a rubber material. The method for improving the fungus-proof performance of the rubber material comprises the steps that 1, master refining of raw rubber is conducted, wherein filler and additives are added into the raw rubber, then master refining is conducted for 35-45 minutes, and the additives include a plasticizer and an anti-aging agent; 2, filtering is conducted, wherein fine filtration is conducted on the refined raw rubber with two layers of screens with meshes ranging from 80 to 100; 3, mixing is conducted, wherein mixing is conducted for 20-25 minutes at the temperature ranging from 40 DEG C to 55 DEG C after a mildew preventive and a vulcanizing agent are added to the filtered raw rubber according to the different types of the rubber, and the roller interval for mixing ranges from 2 mm to 2.5 mm, and the mildew preventive is the mildew preventive O or the mildew preventive BCM. By the adoption of the method, the fungus-proof performance of the rubber material can be improved remarkably, and meanwhile the physical and mechanical performance of the rubber material is not affected.

Description

technical field [0001] The invention belongs to the aviation material manufacturing technology, and relates to a method for improving the anti-mold performance of rubber materials. Background technique [0002] After non-metallic materials are in a hot and humid state for a long time, a large number of molds will grow on their surfaces. The growth of microorganisms such as mold absorbs nutrients from the material, discharges acidic substances to corrode the material, reduces the performance of the material, accelerates aging, affects the function of non-metallic parts (such as sealing, wear resistance, etc.), and then affects the flight safety of the aircraft. Therefore, in order to ensure the safe flight of aircraft, it is necessary to improve the anti-mold performance of non-metallic materials, which involves five major categories of materials: rubber, plastics, sealants, textiles, and coatings. Contents of the invention [0003] The technical problem to be solved by th...
