Problems solved by technology

[0008] The purpose of the present invention is to solve the problems of existing colored and light-colored cementing materials such as hot paving polluting the environment, inconvenient construction, or harsh technical conditions for cold paving, and to provide a road-use colored cementing that can be directly cold-constructed without further emulsification. Under the premise of ensuring that the performance indicators of the color binder are met, the components and preparation methods of the color binder emulsion are changed to achieve stability, energy saving, material saving and environmental protection

preparation example Construction

[0027] The preparation method of the above-mentioned colored binder emulsion is: mix light-colored petroleum distillate oil, petroleum resin and oil-soluble organic pigments at 120°C to 140°C, then add a surfactant aqueous solution at about 60°C, and emulsify through an emulsifying machine to obtain Emulsion A; Emulsion A and Emulsion B are uniformly mixed to obtain a color binder emulsion.

[0028] Emulsion A and emulsion B can be stored separately, and then mixed to obtain the target product when used on site.

specific Embodiment

[0030] The compositions of Examples 1-5 of the emulsion A are shown in Table 1, the ratio of the emulsion A and the emulsion B is shown in Table 2, and the properties of the distillation residue of the colored cement emulsion are shown in Table 3.

[0031] Among them: organic pigments are one (or more) of the following: plastic medium yellow HRG, permanent orange GC or permanent red RB

[0032] Emulsion B is one (or two) of the following: SBS latex or SBR latex.

[0033] The surfactant is one of the following: cetyltrimethylammonium bromide, alkylphenol polyoxyethylene ether.

Embodiment 1

[0035]Mix 28 parts of light-colored petroleum distillate oil, 68 parts of petroleum resin (softening point 120°C) and 4 parts of oil-soluble organic pigment plastic medium yellow HRG at 130°C±5°C and add to 72 parts at 60°C±5°C. In the aqueous solution of hexaalkyltrimethylammonium bromide, emulsion A can be obtained by emulsifying with an emulsification machine; 95 parts of emulsion A and 5 parts of SBR latex are mixed uniformly to obtain the product.

Abstract

The invention relates to a latex with colorized cementing agent, which is consisted of A latex and B latex. The characteristics of the invention: the A latex is produced through the emulsification of the homogeneous mixture of 25-45 shares of light coloured petroleum fraction oil, 30-70 shares of petroleum resin and 3-8 shares of oil-soluble organic pigments; the B latex is rubber latex with colorized cementing agent; The A latex and the B latex are well mixed in the proportion of 80-95 shares: 5-20 shares, and then the latex with colorized cementing agent is produced. The invention can directly cold-applied without emulsification, and has the advantanges of stabilization, energy-efficiency, material -saving and environmental protection.

Description

technical field [0001] It relates to emulsified asphalt, which belongs to pavement building materials. Background technique [0002] Pave the road with colored mixtures, for the function of distinguishing road sections and lanes, improve the driver's recognition effect, increase the traffic capacity of the road and strengthen traffic safety to induce traffic flow, make traffic management intuitive, and use colored mixtures to decorate urban streets, Squares, parks, sidewalks in residential quarters, and sports grounds to beautify the city, show the city's style, and improve the living environment are not only the needs of people's traffic awareness and improvement of material living standards, but also the embodiment of social progress and material civilization. Domestically, paving has been successfully carried out in more than 20 cities such as Beijing, Xiamen, Guangzhou, Ningbo, Guilin, Yantai, etc., and the effect is quite good. [0003] Colored cement mixture is usuall...
