Description
Technical Field
The invention belongs to the technical field of pavement bonding materials, and particularly relates to an epoxy resin-based composite bonding material for a solar power generation pavement.
Background
It is well known that as ozone in the atmosphere is reduced, the radiation of ultraviolet light is increased. Ultraviolet light is a generic term for radiation in the electromagnetic spectrum having a wavelength of 10nm to 400nm, wherein ultraviolet light having a wavelength of 280nm to 400nm can cause aging of a material by breaking chemical bonds in the material. The solar power generation road surface is a road surface which converts solar energy into electric energy, is laid above a roadbed and is formed by connecting a plurality of solar panels. The connected solar panels are bonded through special bonding materials. Most of the currently used bonding materials are epoxy resin-based adhesives, and the epoxy resin-based adhesives are easy to age and embrittle under the irradiation of strong ultraviolet rays, so that the service life of the epoxy resin-based adhesives is shortened, and the phenomena of dislocation, looseness and the like of the bonded adjacent solar panels are caused. Therefore, it is a key point of industry research and development to find an adhesive material capable of resisting ultraviolet radiation to prolong the service life of the solar power generation pavement.
Disclosure of Invention
Aiming at the problem that the bonding material of the solar power generation pavement in the prior art is poor in ultraviolet resistance, the invention provides an epoxy resin-based composite bonding material for the solar power generation pavement, and aims to solve the problem.
The technical scheme of the invention is as follows:
an epoxy resin-based composite bonding material for a solar power generation pavement comprises a component A and a component B; the component A comprises the following components in parts by weight: 58-70 parts of bisphenol A type epoxy resin, 5-7 parts of ultraviolet absorbent, 15-20 parts of toughening agent, 20-30 parts of heat conducting agent, 2-8 parts of catalyst and 20-30 parts of solvent. The component B comprises the following components in parts by weight: 10-15 parts of diphenylmethane diisocyanate and 5-10 parts of a viscosity regulator.
Preferably, the composition comprises the following components in parts by weight: and (2) component A: 66 parts of bisphenol A epoxy resin, 6 parts of ultraviolet absorber, 16 parts of toughening agent, 24 parts of heat conducting agent, 6 parts of catalyst and 25 parts of solvent. And (B) component: 12 parts of diphenylmethane diisocyanate and 7 parts of viscosity regulator.
Preferably, the ultraviolet absorbent is 3, 5-diisopropyl phenyl salicylate. The ultraviolet absorbent selected by the invention can react with the epoxy resin and then is used as a part of the bonding material to play a role in absorbing ultraviolet rays. Compared with the common physical mixed ultraviolet absorbent, the ultraviolet absorbent is used as a part after curing through chemical reaction, so that the firmness of the bonding material can be improved, and the bonding material and the cured resin form a complete system.
Preferably, the heat conducting agent is one or a combination of more of andalusite, gibbsite and bayer stone. After long-time ultraviolet radiation, the ultraviolet absorbent can absorb high-energy ultraviolet light, convert the high-energy ultraviolet light into fluorescence and phosphorescence, and release the fluorescence and phosphorescence in the form of heat energy to play a role in resisting ultraviolet. The heat conducting agent is added into the bonding material, so that heat can be conducted and removed in time, and heat accumulation is prevented. Meanwhile, the selected heat-conducting agent also has higher compressive strength, so that the overall strength of the cured material can be improved.
Preferably, the particle size of the heat conducting agent is 20-100 μm.
Preferably, the catalyst is 2,4, 6-tris (dimethylaminomethyl) phenol. 2,4, 6-tris (dimethylaminomethyl) phenol can be used as a nucleophile to attack carbon atoms in the NCO group to form an active intermediate. The reactive intermediate has high activity and can further initiate the reaction of isocyanate and epoxy resin to generate cyclic oxazolidinone. The ring-formed structure has stronger characteristics than the branched structure, and can be kept unchanged for a long time when exposed to strong light, high humidity and high heat and the like outdoors.
Preferably, the toughening agent is one of dioctyl phthalate, dibutyl phthalate, triphenylphosphine or 2,4, 5-trichlorophenol.
Preferably, the solvent is acetone.
Preferably, the viscosity modifier is N, N-dimethylformamide.
The technical scheme of the invention also comprises that the component A and the component B are separately prepared when the epoxy resin-based composite adhesive material is prepared. When in use, the component A and the component B are mixed and stirred uniformly according to the mass ratio of 1:1 for use.
The invention has the beneficial effects that:
the epoxy adhesive material provided by the invention can resist ultraviolet radiation, and the service life of a solar pavement is prolonged. 3, 5-diisopropyl phenyl salicylate which can react with epoxy resin is added into the components, so that the ultraviolet absorbent is fused in the molecular structure of a cured product to form a whole. The catalyst selected by the invention can be used as a nucleophilic reagent to attack carbon atoms in NCO groups to generate an active intermediate. The reactive intermediate has high activity and can further initiate the reaction of isocyanate and epoxy resin to generate cyclic oxazolidinone. The ring-formed structure has stronger characteristics than the branched structure, and can be kept unchanged for a long time when exposed to strong light, high humidity and high heat and the like outdoors.
