Problems solved by technology

However, the prior art has the following problems: due to the small particle size of the inorganic salt (large specific surface area), the amount of used wax, asphalt or various resins (such as patent document 3) will be very large, which is uneconomical; The physical way of wrapping, the surface of the particles is difficult to wrap evenly, and the organic matter is sticky, the wrapped particles will be bonded together, in order to disperse the bonded particles, the follow-up production workload will be very huge, and it is difficult to achieve real industrialization

[0064]

[0065] The snow-melting paint of the present invention can be prepared by mixing silicone-based materials, asphalt, silane coupling agents, catalysts, the slow-release snow-melting modifiers of the present invention, and fillers, silane coupling agents, and the above-mentioned other components. get. The order of addition of the components constituting the anti-icing paint is not particularly limited, and the above-mentioned mixing can be performed using a commonly known mixer.

[0066]

[0067] The curing temperature of the snow-melting paint of the present invention is not particularly limited. Preferably, for the needs of outdoor construction, the curing of the snow-melting paint of the present invention is usually carried out at ambient temperature.

[0068] Below in conjunction with example the present invention will be further described, but the present invention is not limited to following example. Unless otherwise specified, the term "part" means "part by...

Embodiment 1

[0089] Add 40 parts of emulsified bitumen to 100 parts of Stir in EL 39 silicone emulsion at a speed of 200rpm for 10min, add 16 parts of the slow-release snow-melting modifier prepared in Production Example 3 and stir for 15min at a speed of 200rpm, add 3 parts of vinyl tris(β-methoxyethylene) Oxygen) silane, while adding 1.0 parts of dibutyltin dilaurate and stirring at a speed of 300rpm for 20min, and finally adding 10 parts of 40 mesh emery, and stirring at a speed of 300rpm for 30min. A hydrophobic slow-release silicone coating is obtained.

Embodiment 2

[0091] A silicone coating was obtained in the same manner as in Example 1, except that the slow-release snow-melting agent modifier in Example 1 was replaced with the slow-release snow-melting agent prepared in Production Example 4.

Abstract

The invention relates to preparation methods of a slow-release snow-melting agent and a snow-melting coating thereof. The prepared slow-release snow-melting agent is characterized in that water-soluble inorganic or organic salt is coated in vesicle micelles of an amphiphilic block copolymer. The amphiphilic segmented copolymer comprises a block copolymer of polyacrylic acid and polystyrene, and ablock copolymer of poly(N,N-dimethylacrylamide), polystyrene and the like. The amphiphilic block copolymer is taken as a coating material, a hydrophilic chain segment of the amphiphilic block copolymer has good compatibility with a water-soluble inorganic / organic salt, and a good cladding effect on the water-soluble inorganic / organic salt is achieved; the hydrophobic chain segment polystyrene hasgood compatibility with an organic silicon coating, construction is easier, and when the hydrophobic chain segment polystyrene is used in the snow-melting coating, a snow-melting coating layer formedby the snow-melting coating has excellent hydrophobicity, slow release property and long service life.

Description

technical field [0001] The invention relates to a slow-release deicing agent and a manufacturing method thereof. Background technique [0002] Snow and ice on roads in winter has always been a problem that plagues road traffic safety. Snow and ice on the road surface will greatly reduce the anti-skid ability of the road surface, which not only weakens the traffic capacity of the road, is prone to vicious traffic accidents, but also damages the road and its subsidiary structures. In severe cases, it will cause traffic interruption and make people's lives Production and production cannot be carried out normally, and even endanger the safety of people's lives and property. [0003] At present, the commonly used road surface deicing methods are generally divided into two categories: passive suppression type and active ice and snow melting type. Commonly used passive suppression ice and snow removal measures mainly include spreading deicing agent, artificial snow removal, mecha...
