Problems solved by technology

This inhomogeneity leads to the reduction or blockage of the lower gap of the structure, which affects the water permeability of the structure, causes pure accumulation of rainwater, and affects the natural circulation of rainwater.
More importantly, due to the accumulation of liquid synthetic resin at the bottom of the structure, the amount of resin in the upper layer of the structure is reduced, resulting in a decrease in the mechanical strength of the surface of the structure.
[0004] In addition, bisphenol-type epoxy resins are currently widely used in road paving in Japan. As time goes by, the resins will turn yellow and lose their luster, which will affect the appearance of the structure.

experiment example

[0037] Preparation of weather-resistant fibrous epoxy resin adhesive and its structure:

[0038] Add 30g of rock wool fiber, 100g of glass fiber, 40g of tackifier, and 15g of siliconized cement to 1000g of cycloaliphatic epoxy resin, stir and mix thoroughly at a temperature of 30-50°C to saturate and saturate various fiber resins to form Weather-resistant epoxy resin type fibrous resin. Add 500 g of non-yellowing and alicyclic polyamine to the above-mentioned fibrous resin, and mix uniformly to form a weather-resistant fibrous resin adhesive. Add 30Kg of light-colored sand grains (4-6mm) to the above-mentioned adhesive, mix evenly, and after a day of curing, a weather-resistant epoxy resin type fibrous resin adhesive structure is obtained. The bending strength of this structure is 113Kg / cm 2 , the compressive strength is 304Kg / cm 2 , porosity of 20 to 35%, with excellent strength performance and water permeability.

Abstract

The invention discloses a weathering-resistant and permeable adhesive for paving a road and its constitutional body, wherein the bonding agent comprises weatherability fibrosis epoxy resin and weatherability modified ring form polyamine. The bonding agent possesses high strength, ductility, and yellow / white conversion resistance.

Description

technical field [0001] The present invention relates to an adhesive and its structure, in particular to an adhesive and its structure for weather-resistant and water-permeable road pavement. Background technique [0002] Asphalt or cement is traditionally used for paving roads (such as walkways, driveways and park landscape roads). When roads containing asphalt or cement are used, harmful components in asphalt or cement will dissolve, causing environmental pollution. pollution, therefore, looking for an environmentally friendly adhesive for road paving and its structure has become a research topic. [0003] At present, in foreign countries (such as in Japan), in order to replace asphalt and cement adhesives, liquid synthetic resins are generally used. The liquid synthetic resin is used as a binder to avoid the dissolution of a large number of harmful components of asphalt, and also to prevent the dissolution of alkaline components of cement, which may cause rivers and the e...
