High-strength fiberglass methane tank and preparation method thereof

Abstract

The invention discloses a high-strength fiberglass methane tank. The high-strength fiberglass methane tank is characterized in that the fiberglass methane tank is made from unsaturated polyester-fiber reinforced bulk molding compounds which are prepared from, by weight, 25-45 parts of unsaturated polyester, 15-30 parts of reinforced fibers, 10-15 parts of aldehyde-modified crosslink polyesyrene, 0.3-0.5 part of N,N-dimethylaniline, 0.2-0.4 part of an initiating agent, 35-45 parts of magnesium oxide, 0.1-0.3 part of nanosilicon dioxide, 0.5-2 parts of a coupling agent, 0.02-0.1 part of calcium hydroxide, 1-3 parts of polyoxyethylene castor bean oil, 0.5-2 parts of stearic acid zinc salt, 3-7 parts of styrene, 0.1-0.3 part of p-benzoquinone and 0.2-0.5 part of 2,6-butylated hydroxytoluene. The fiberglass methane tank is good in toughness and strength, the height of anti-shock strength is greater than or equal to 160J/m<2>, and the tank is anti-corrosion and heat-resistant, good in oxidation resistance and capable of meeting requirement of the high-strength giberglass methane tank.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-strength fiberglass biogas digester and a preparation method thereof. Background technique [0002] The construction of biogas digesters in the vast rural areas of China has been listed by the Ministry of Environmental Protection as a "core technology to solve rural pollution", by the Ministry of Agriculture as "new rural renewable clean energy", and by the central leading group for new rural construction as "socialist" Comprehensive technology for new rural construction". The construction of household biogas digesters can drive farmers to renovate kitchens, toilets, and circles, and is conducive to the promotion of energy ecological models. Promote the development of circular agriculture. At present, some biogas digesters are mostly made of cement, concrete and other materials. Since the molecular diameter of methane is small, while the porosity of cement and c...

AI Technical Summary

Problems solved by technology

At present, some biogas digesters are mostly made of cement, concrete and other materials. Since the molecular diameter of methane is small, while the porosity of cement and concrete is relatively large, under pressure, the molecular diameter of methane determines the biogas capacity. Easy to leak from digesters made of concrete

At the same time, this kind of biogas digester material also has heavy quality, poor thermal insulation, and cumbersome manufacturing process, which is not convenient for industrial prefabrication, and has poor tensile and strength properties, and is easily corroded, and its thermal insulation performance is not outstanding.
