Embodiment 1

[0039] Example 1: An environmentally friendly and efficient snow-melting pavement coating material

[0040] The coating material is made of the following raw materials in parts by weight:

[0041] Potassium acetate 100 parts, single-component fluorocarbon resin 50 parts, ethyl cellulose 6 parts, hydroxypropyl methylcellulose 0.7 parts, diethyl phthalate 0.9 parts, PEG-400 0.105 parts, glycerin 0.03 parts , 0.03 parts of magnesium stearate, 0.01 parts of talc powder, 8 parts of calcium carbonate, 2 parts of barium sulfate, 1 part of YF-001 fluorocarbon high-efficiency leveling agent (purchased from Hubei Youshida Technology Co., Ltd.), TMC-TE Titanate coupling agent (purchased from Tianchang Green Chemical Auxiliary Factory) 0.02 part, simethicone 0.001 part, PEG-60000.2 part, hydrophobic fumed silica 0.1 part.

Embodiment 2

[0042] Example 2: A preparation method of an environmentally friendly and efficient snow-melting pavement coating material

[0043] Embodiment 1 The preparation method of an environmentally friendly and efficient snow-melting pavement coating material is as follows:

[0044] 1. Take raw materials according to the parts by weight described in Example 1;

[0045] 2. Surface modification of fillers and semi-reinforcing agents:

[0046] (1) Dilute the TMC-TE titanate coupling agent with ethanol at a volume ratio of 10:1 to obtain an ethanol dilution;

[0047] (2) Add calcium carbonate to m / v as 1:0.025 (kg / m 3 ) ratio into the obtained ethanol dilution;

[0048] (3) Stir for 0.6-1.0 hours under the conditions of 40°C-60°C and 500-600r / min;

[0049] Stand still for 2 hours until all the solids are precipitated, remove the supernatant ethanol solution, dry in a drying oven to remove residual ethanol, and obtain modified filler E;

[0050] (4) Add barium sulfate to m / v as 1:0.02...

Embodiment 3

Abstract

The invention discloses an environmentally friendly efficient snowmelt pavement coating material and a preparation method and applications thereof, and aims to solve the technical problems that the ice removing cost in winter is high, the environment is polluted by the snow melting agents, the roads and the environment are damaged by an ice removing technology, and the snow melting means cannot last for a long time. The coating material is made of following raw materials: a snow melting agent, a binding material, a hydrophobic coating material, a hydrophilic coating material, a hydrophobic plasticizer, a hydrophilic plasticizer, glycerin, an anti-sticking agent, talcum powder, a filling material, a semi-reinforcing agent, a leveling agent, a coupling agent, an antifoaming agent, a pore forming agent, and a hydrophobic fumed silica. The invention further provides a preparation method of the coating material, and the coating material is applied to snow melting of traffic roads. The coating material is green and environmentally, and can well protect the pavement. The raw material sources are wide, the cost is low, the production technology is simple and easy to operate and is suitablefor large scale application and popularization, a great amount of human resources and materials is saved, and a great economic value is created.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to an environment-friendly and high-efficiency snow-melting pavement coating material and its preparation method and application. Background technique [0002] With the advent of winter rain and snow, the rain and snow will stick together with the road under the rolling of vehicles, and the depth of the road surface structure will be filled with snow, resulting in a decrease in the adhesion coefficient of the road surface, causing the vehicle to skid, greatly reducing the adhesion coefficient of the road surface, and giving the road a smooth and smooth road. Serious adverse effects on driving safety. [0003] The method of deicing snow at present has manual, mechanical deicing and spreading deicing agent deicing. Manually use a lot of people to shovel snow with various tools, which consumes a lot of manpower and material resources; and manual and mechanical methods cannot ...
