Description

Technical Field

[0001] The invention relates to the technical field of adhesive materials, and in particular to a multi-surface epoxy resin-based adhesive structural layer material specially used for solar power generation pavement. Background Art

[0002] The full name of solar power generation pavement is "solar photovoltaic power generation pavement", which means that the traditional asphalt or cement concrete surface layer is replaced by a solar photovoltaic power generation layer, or the solar photovoltaic power generation layer is directly laid on the existing asphalt or cement concrete pavement. Therefore, the solar power generation pavement layer and the cement concrete or asphalt concrete of the roadbed, as well as the various structural layers of the solar power generation pavement layer, need to be bonded with bonding materials. The existing technology multi-surface structural layer bonding materials mostly use epoxy resin-based adhesives. Epoxy resin is widely used as an adhesive after being cured and cross-linked under the action of a curing agent. However, epoxy resin-based adhesives have some inherent defects: stress relaxation and creep will occur under the action of long-term stress, the bonding strength will also decrease with the passage of time, and the plastic deformation will also increase, resulting in poor durability; at the same time, the cured material is brittle and has poor toughness. Summary of the invention

[0003] In view of the problems of poor durability and toughness of existing epoxy resin-based adhesives, the present invention provides a multi-surface epoxy resin-based bonding structural layer material specially used for solar power generation pavement, which has excellent toughness and durability after curing.

[0004] In a first aspect, the present invention provides a multi-surface epoxy resin-based bonding structural layer material for solar power generation pavement, comprising component A and component B, wherein the weight ratio of component A to component B is 3-5:1. Component A includes bisphenol epoxy resin, coal tar, antioxidant, bactericide, ultraviolet absorber, filler and diluent; Component B includes a polyamide curing agent and dimethylformamide; The polyamide curing agent is KM-115.

[0005] Further, component A includes, by weight, 50-70 parts of bisphenol epoxy resin, 10-15 parts of coal tar, 0.5-3 parts of antioxidant, 0.5-3 parts of bactericide, 0.3-1.5 parts of ultraviolet absorber, 0.5-3 parts of filler and 15-25 parts of diluent; In parts by weight, component B includes 70-80 parts of a polyamide curing agent and 20-30 parts of dimethylformamide.

[0006] Further, in parts by weight, component A includes 70 parts of bisphenol epoxy resin, 14 parts of coal tar, 3 parts of antioxidant, 1.5 parts of bactericide, 1.5 parts of ultraviolet absorber, 3 parts of filler and 20 parts of diluent; In parts by weight, component B includes 80 parts of a polyamide curing agent and 20 parts of dimethylformamide.

[0007] Furthermore, the antioxidant in component A is a mixture of antioxidant 264 and antioxidant 1010 in a mass ratio of 1.5-3:1; adding the antioxidant can slow down aging and improve the weather resistance of the epoxy resin, thereby improving durability.

[0008] Furthermore, the fungicide is cuprous oxide or glutaraldehyde; by adding the fungicide, the resistance of the epoxy resin to biological attack can be improved, and microbial corrosion of the solar power generation pavement can be prevented.

[0009] Furthermore, the ultraviolet absorber is at least one of TINUVIN405, TINUVIN479 or TINUVIN477.

[0010] Furthermore, the filler is calcium lignin sulfonate, which can improve the dispersibility and adhesion of the epoxy resin.

[0011] Furthermore, the diluent is D-1402, which is colorless, transparent, and has low viscosity. It is used as a toughening diluent for epoxy resin to improve the toughness and mechanical strength of epoxy resin.

[0012] In a second aspect, the present invention also provides a method for preparing a multi-surface epoxy resin-based bonding structural layer material for a solar power generation pavement, the preparation method comprising the following steps: (1) Preparation of component A: bisphenol epoxy resin, coal tar, antioxidant, fungicide, filler and ultraviolet absorber are added into a cylinder in sequence, stirred at a speed of 500-800 r / min for 20-30 min, and a diluent is added at a speed of 300-400 r / min to obtain component A; (2) Preparation of component B: adding a polyamide curing agent to dimethylformamide to obtain component B; (3) Mixing component A and component B: Mix component A and component B in a weight ratio of 3-5:1 to obtain the product.

[0013] The beneficial effects of the present invention are: The present invention provides a multi-surface epoxy resin-based bonding structural layer material specially used for solar power generation pavement, which has excellent toughness and durability after curing. To achieve the above effects, firstly, the durability of the bonding material is a reliable guarantee for connecting the structural layers. The present invention adds coal tar, antioxidant, bactericide and ultraviolet absorber to component A, wherein the addition of coal tar can improve the water resistance of the epoxy resin and improve the photosensitivity to the sun; the addition of antioxidant, bactericide and ultraviolet absorber can slow down aging and corrosion and improve the service life of the bonding material; the above components synergistically enhance the effect and improve the durability of the bonding material; secondly, the bisphenol epoxy resin bonding agent has the disadvantage of brittle cured product, and the toughening diluent is used to improve the toughness and mechanical strength of the epoxy resin; calcium lignin sulfonate improves the bonding property; at the same time, polyamide is used as a curing agent and dimethylformamide is used to adjust the viscosity, so that the epoxy resin cured product has good workability, bonding property and toughness.

[0014] The present invention optimizes and improves the formula, greatly improving the toughness and durability of the structural layer material while ensuring that the mechanical properties and adhesion of the bonding structural layer are improved, providing a strong guarantee for the development of solar power generation pavement engineering.
