preparation example Construction

[0041] The above-mentioned colored modified epoxy resin used for colored greenway paving materials is prepared by the following method.

[0042] Correspondingly, the embodiment of the present invention also provides a method for preparing a colored modified epoxy resin used in colored greenway pavement materials. The method comprises the steps of:

[0043] A preparation method for a colored modified epoxy resin for colored greenway paving materials, comprising the steps of:

[0044] S01. Weigh each component substance according to the above-mentioned color modified epoxy resin used for the color greenway pavement material;

[0045] S02. Premixing the silane coupling agent with the nano diatomaceous earth to obtain a first mixture;

[0046] S03. Preheat the epoxy resin, add the first mixture into the preheated epoxy resin, mix evenly by high-speed shearing, then add the toner, the heavy calcium powder, and the microcalcium powder in sequence. After the silicon powder, the di...

Embodiment 1

[0074] The colored modified epoxy resin that is used for colored greenway pavement material comprises following components by weight:

[0075] 100 parts of epoxy resin, 10 parts of heavy calcium powder, 5 parts of silica fume, 1 part of nano-diatomaceous earth, 1 part of silane coupling agent, 3 parts of toner, 0.5 parts of anti-aging agent, 0.5 parts of dispersant, stabilizer 1 serving. Wherein, the epoxy resin is E51 epoxy resin; the heavy calcium powder is 600 mesh heavy calcium powder; the microsilica is 600 microsilica; the nano diatomaceous earth is nano diatom soil; the silane coupling agent is a KH-550 coupling agent; the toner is 300 mesh red color toner; the anti-aging agent is a salicylate UV absorber; the dispersion The agent is ethanol; the stabilizer is an ammonium salt cationic surfactant.

[0076] The preparation method of the colored modified epoxy resin that is used for colored greenway pavement material is as follows:

[0077] First, premix the silane cou...

Embodiment 2

[0079] The colored greenway pavement material comprises the following parts by weight:

[0080] 100 parts of coarse aggregate, 5 parts of fine aggregate, 1 part of filler, 4 parts of colored modified epoxy resin used in colored greenway paving materials prepared in Example 1, and 4 parts of curing agent. Wherein, the coarse aggregate is 3-6mm stone, the fine aggregate is 0-3mm stone, the filler is mineral powder, and the curing agent is an amine curing agent.

[0081] The preparation method of the colored greenway pavement material is as follows: the color modified epoxy resin and curing agent for the colored greenway pavement material prepared in Example 1 are added to the stirring pot according to the mass ratio, and stirred manually or mechanically 3min, then add coarse aggregate and fine aggregate in turn, continue to stir for 2min, finally add filler, continue to stir for 1min, and get the colored green road pavement material.

Abstract

The invention provides colored modified epoxy resin for a colored greenway paving material. The colored modified epoxy resin comprises the following components in parts by weight: 100-102 parts of epoxy resin, 10-20 parts of ground calcium carbonate, 5 to 10 parts of silica fume, 1 to 5 parts of nanometer diatomite, 1-5 parts of a silane coupling agent, 3-6 parts of a toner, 0.5 to 1 part of an anti-aging agent, 0.5-1 part of a dispersing agent, and 1-2 parts of stabilizer. The colored greenway paving material is provided and comprises the following components in parts by weight: 100-102 partsof coarse aggregate, 5 to 10 parts of fine aggregate, 1-5 parts of a filler, 4-7 parts of the color modified epoxy resin, and 4-7 parts of a curing agent, wherein the mass ratio of the color modifiedepoxy resin to the curing agent is 1: 1.

Description

technical field [0001] The invention relates to the field of urban road materials, in particular to a colored green road pavement material and a preparation method. Background technique [0002] Sponge city is a new concept of ecological city. Its most important feature is "absorbing water, storing water, seeping water, purifying water when it rains, and releasing water when needed". The construction of sponge city needs to improve several aspects such as underground comprehensive pipe gallery, permeable pavement pavement, and permeable non-motor vehicle lane pavement. Among them, the research on underground comprehensive pipe gallery and permeable pavement pavement is relatively sufficient, although there are not many implementation cases. But the theoretical feasibility is already high. [0003] At present, urban bicycles are prevalent, and more and more people choose bicycles for environmentally friendly travel. This puts forward higher requirements for greenway pavement...
