Problems solved by technology

And the use of those equipments has caused the expansion of funds and the waste of labor force to a certain extent.
Canned cement requires relatively large investment, and storage tanks cannot be mixed with black asphalt, and the actual situation of domestic colored pavement projects, one or several small projects, the last set of tanks will not increase the cost. few

Embodiment 1

[0020] Prepare the reaction kettle, keep stirring at high speed in the kettle to fully mix the added materials; add 500 grams of heavy mineral oil to the kettle at room temperature; raise the temperature to 140°C, add 300 grams of C5-C10 petroleum resin; then raise the temperature to 160°C, add 40 grams of SBR and 60 grams of PE; then raise the temperature to 180°C, add 10 grams of anti-aging agent, 10 grams of heat stabilizer and 10 grams of ultraviolet stabilizer; at 160-220°C, keep warm for 6 hours; add and remove Molding agent and surfactant, after stirring evenly, stop stirring to obtain cement; then use high-pressure vacuum to discharge air bubbles in the cement, wait for the temperature of the cement to drop to about 20°C above the softening point, add fillers, colorants, and mix uniform, and then lead the cement into the extruder, cool, shape and cut to obtain granular color pavement cement.

Embodiment 2

[0022] Prepare the reaction kettle, and keep stirring at high speed in the kettle to fully mix the added materials; add 400 grams of heavy mineral oil to the kettle at room temperature; raise the temperature to 140°C, add 500 grams of C5-C10 petroleum resin; then raise the temperature to 160°C, add 30 grams of SBR, 40 grams of PS and 30 grams of PP; then raise the temperature to 180°C, add 3 grams of anti-aging agent, 3 grams of heat stabilizer and 4 grams of ultraviolet stabilizer; at 160-220°C, keep warm for 10 hours ; Add release agent and surfactant, after stirring evenly, stop stirring to obtain cement; then use high-pressure vacuum to discharge air bubbles in the cement, wait for the temperature of the cement to drop to about 20°C above the softening point, add fillers, coloring agent, mixed evenly, and then the binder is introduced into the extruder, cooled, shaped and cut to obtain granular colored binder for pavement.

Embodiment 3

[0024] Prepare the reaction kettle, keep stirring at a high speed in the kettle to fully mix the added materials; add 600 grams of heavy mineral oil to the kettle at room temperature; raise the temperature to 140°C, add 400 grams of C5-C10 petroleum resin; then raise the temperature to At 160°C, add 20 grams of SBR and 50 grams of PP; then raise the temperature to 180°C, add 7 grams of anti-aging agent, 7 grams of heat stabilizer and 6 grams of ultraviolet stabilizer; at 160-220°C, keep warm for 8 hours; add and remove Molding agent and surfactant, after stirring evenly, stop stirring to obtain cement; then use high-pressure vacuum to discharge air bubbles in the cement, wait for the temperature of the cement to drop to about 20°C above the softening point, add fillers, colorants, and mix uniform, and then lead the cement into the extruder, cool, shape and cut to obtain granular color pavement cement.

Abstract

The present invention discloses color facing binding material palletizing process, which includes the following steps: 1. mixing materials; 2. reaction at 160-220 deg.c for 6-10 hr; 3. adding demolding agent and surfactant and stirring to obtain the binding material; and 4. vacuum debubbling the binding material, adding stuffing and colorizing agent at the temperature 20 deg.c higher than the softening point and mixing, extruding in an extruder, cooling, settling and cutting to obtain pelletized color facing binding material. The pelletized color facing binding material has easy use and high construction efficiency.

Description

【Technical field】 [0001] The invention relates to a novel granulation process for pavement materials, in particular to a granulation process for high-molecular polymer binders for colored pavement. 【Background technique】 [0002] In order to reflect the characteristics of a certain city or region, from the middle of last century, some western countries began to devote themselves to the research of colored pavement technology, in order to change the monotonous and boring situation of traditional black and white pavement, so as to beautify the environment and make people spiritual Invigorating, prompting, reminding and alerting and other road traffic organization and control functions. At the end of the last century, our country also began to carry out research work on color paving technology. [0003] There are two main types of new binders for colored pavement: the first is to decolorize traditional black asphalt. The existing asphalt decolorization technology is mainly com...
