preparation example Construction

[0046] The present invention provides a preparation method of the dark green thermal resistance material described in the above technical solution, comprising the following steps:

[0047] mixing epoxy resin, pigments and fillers with some diluents to obtain the first slurry;

[0048] Mixing the first slurry with dark green colored fillers and film-forming aids to obtain a second slurry;

[0049] The second slurry is mixed with the polyamide curing agent and the remaining diluent to obtain a dark green thermal resistance material.

[0050] In the present invention, epoxy resin, pigment and filler are mixed with part of diluent to obtain the first slurry. In the present invention, the mixing of the epoxy resin, pigments and fillers and part of the diluent is preferably to mix the epoxy resin and the pigments and fillers, stir at 50-70 rpm for 2-4 minutes, and then add part of the diluent to the resulting mixture , and stirred at 50-70 rpm for 3-5 minutes to obtain the first s...

Embodiment 1

[0056] In parts by weight, mix 11 parts of diatomaceous earth, 28.1 parts of rutile titanium dioxide and 23 parts of E-51 epoxy resin, stir at 60 rpm for 3 minutes, then add 10 parts of acetone, and stir at 60 rpm for 4 minutes to obtain the a slurry;

[0057] In the first slurry, add 5 parts of iron oxide green and 0.9 part of iron oxide black, stir at 60rpm until the color is uniform; then add 0.6 part of film-forming aid (the film-forming aid comprises tributyl phosphate, Acrylic ester and TEGO Dispers740W wetting and dispersing agent, the mass ratio of described tributyl phosphate, acrylate and TEGO Dispers 740W wetting and dispersing agent is 2:3:3), stirred at 60rpm for 3min, obtained the second slurry;

[0058] Add 9 parts of 650 polyamide curing agent to the second slurry, stir at 60 rpm for 5 minutes, then add 13 parts of acetone, and stir at 60 rpm for 4 minutes to obtain a dark green thermal resistance material.

Embodiment 2

[0060] In parts by weight, mix 9 parts of diatomaceous earth, 26 parts of rutile titanium dioxide and 27 parts of E-51 epoxy resin, stir at 60 rpm for 3 minutes, then add 11 parts of acetone, and stir at 60 rpm for 4 minutes to obtain the a slurry;

[0061] Add 5.5 parts of iron oxide green and 0.8 part of iron oxide black in the first slurry, stir at 60rpm until the color is uniform; then add 0.6 part of film-forming aid (the film-forming aid comprises tributyl phosphate, Acrylic ester and TEGO Dispers740W wetting and dispersing agent, the mass ratio of described tributyl phosphate, acrylate and TEGO Dispers 740W wetting and dispersing agent is 2:3:3), stirred at 60rpm for 3min, obtained the second slurry;

[0062] Add 10 parts of 650 polyamide curing agent to the second slurry, stir at 60 rpm for 5 minutes, then add 11 parts of acetone, and stir at 60 rpm for 4 minutes to obtain a dark green thermal resistance material.

Abstract

The invention provides a dark green thermal resistance material. The dark green thermal resistance material is prepared from the following components, in parts by weight: 20-30 parts of epoxy resin, 8-12 parts of polyamide curing agent, 36-50 parts of pigment filler, 5.3-6.5 parts of dark green coloring filler, 18-28 parts of diluents and 0.5-0.6 part of film-forming assistant agent, wherein the pigment filler is diatomite and rutile titanium dioxide, and the film-forming assistant agent is a defoaming agent, a leveling agent and a dispersing agent. Epoxy resin is taken as a main body and usedby cooperating with the pigment filler, diatomite and rutile titanium dioxide, the dark green coloring filler is added, and under the effects of the film-forming assistant agent, the diluents and thepolyamide curing agent, the dark green thermal resistance material is obtained. The dark green thermal resistance material is good in thermal resistance effect and convenient to construct, has the effect of beautifying the environment, and is suitable for being applied and popularized in greenways, park pavements, scenic area roads, urban roads, highways and the like.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a dark green thermal resistance material and its preparation method and application. Background technique [0002] Asphalt is a dark brown complex mixture. Asphalt pavement has a very high heat absorption capacity, especially in summer when the temperature of ordinary asphalt pavement is much higher than the air temperature, which can reach 60-70°C, and the highest temperature can reach above 75°C. If the temperature of the road surface is too high, it is easy to produce heat island effect and cause road surface rutting, which brings inconvenience to driving and pedestrians. With the widespread use of asphalt pavement and global warming, people have put forward urgent requirements to reduce the temperature of asphalt pavement in summer and alleviate the urban "heat island effect". [0003] At present, asphalt pavement structures such as large-void pavement and water-ret...
