Abstract

An environmental-protection type oil-resistant sealant is prepared from the following raw materials in parts by weight: 8-15 parts of ethylene glycol, 6-14 parts of a talc powder, 8-15 parts of phenyl silicone oil, 12-24 parts of diethyl methoxy silyloxy, 15-30 parts of carbon black, 12-20 parts of a plasticizer, 15-24 parts of nano calcium carbonate, 0.8-1.7 parts of tackifying resin, 20-32 parts of a flame retardant filler, 1.5-4 parts of a moisture scavenger, 2-7 parts of a heat stabilizer, 0.8-1.8 parts of a glass fiber, 0.8-1.5 parts of magnesium dimethacrylate, 1.5-2.5 parts of paraffin, 0.5-3.2 parts of diacetyl peroxide, and 4-6 parts of epoxy resin. The environmental-protection type oil-resistant sealant has the beneficial effects of good acid and alkali resistance, good oil resistance, stable bonding, elasticity, simple preparation process, no toxicity, no corrosion, and no pollution to the environment.

Description

technical field [0001] The invention relates to an environment-friendly oil-resistant sealant. Background technique [0002] After the 1970s, sealants have been used for joint sealing of building structures and have gradually become the main material. With the development of sealants, sealants are not only used in construction, civil engineering, and bridges, but also widely used in many engineering fields such as containers, ships, electrical, and aerospace. The sealant can be used to fill the configuration gap to play a good sealing effect, and has the functions of anti-leakage, waterproof, anti-vibration, sound insulation, and heat insulation. With the increase of market demand, the requirements for the performance of sealants are also getting higher and higher. Traditional sealants have the defects of poor oil resistance and easy tearing, and will cause certain pollution to the environment, which does not meet the current use requirements. .
