Abstract

The invention discloses an anti-aging sealant and a preparation method thereof. The sealant comprises the following components in parts by weight: 20-30 parts of coumarone indene resin, 5-10 parts of polysulfide rubber, 5-10 parts of nitrile-butadiene rubber, 8-15 parts of tert-butyl phenol-formaldehyde resin, 3-7 parts of silicon dioxide, 2-6 parts of chlorosulfonated polyethylene, 2-7 parts of butyl acrylate, 1-5 parts of aluminum powder, 3-7 parts of sodium metasilicate, 2-8 parts of phosphate, 1-4 parts of triethanolamine, 1-5 parts of boron nitride, 0.5-2 parts of paraffin, 1-3 parts of 2,4-dihydroxy benzophenone and 0.8-3 parts of butyl p-hydroxy benzoate. The preparation method comprises the following steps: adding the components into a reaction kettle, uniformly mixing, heating to 120-140 DEG C under vacuum conditions, stirring to react for 120-180 minutes, and cooling to room temperature. The sealant disclosed by the invention has the advantages of favorable aging resistance and excellent adhesive property, and is more suitable for the field of solar energy.

Description

technical field [0001] The invention belongs to the technical field of sealing material preparation, and in particular relates to an aging-resistant sealant and a preparation method thereof. Background technique [0002] Sealant is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the configuration gap and seal it. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation. Usually dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber are used as the base material, and inert fillers such as talcum powder, clay, carbon black, titanium dioxide and asbestos are added. Plasticizers, solvents, curing agents, accelerators, etc. [0003] A sealant is a flowable or extruded amorphous material to fill a closed joint that can rely on embedded drying, temperature cha...
