Problems solved by technology

[0002] At present, due to the defects and singleness of the dispersed phase structure of modified emulsified asphalt and water-based polymer emulsion at home and abroad, environmental protection road bridges and building room temperature materials cannot meet the requirements of diversification and comprehensiveness. sexual demands
Although domestic water-based resin products are not uncommon, their quality is not stable, and there are few products suitable for comprehensive applications. A considerable part of the water-based products developed by domestic manufacturers have been proved by some domestic manufacturers to have insufficient adhesion performance in the later stage, so these products are not yet available. It is widely used in road and bridge, cement construction, shipbuilding and automobile industries

Embodiment 1

[0034] At present, the pioneers of domestic room temperature asphalt surface materials often face the following problems: the source of asphalt is complex and unstable, and the overall performance of asphalt is low; the speed of demulsification and solidification is difficult to control, which brings trouble and inconvenience to construction and open traffic; And the adhesion is not enough, the asphalt material performance is unsuitable for the new pavement layer.

[0035] Therefore, there is an urgent need for a new generation of modified products of room temperature asphalt pavement materials, and vigorously promote the industrialization process of this new material. The liquid is prepared through experimental design and control of processing parameters such as temperature, pressure, and shear speed. It mainly improves the late adhesion performance of the product and moderately adjusts the viscosity and rapid curing.

[0036] The present invention makes the performance of th...

Abstract

The invention discloses an environmental-protection high-power liquid material for a room-temperature asphalt surface course, which comprises 5-10% of composite water-based polymer emulsion, 50-60% of emulsified asphalt, 5-15% of functional mineral powder and 20-40% of water. The preparation method of the room-temperature asphalt surface course material comprises the following steps: compounding the composite water-based polymer emulsion, which is used as the main body, with the emulsified asphalt; and filling the water and functional mineral powder into the compounded composite water-based polymer emulsion and emulsified asphalt. The invention has the advantages of low investment for production and application, quick effect taking, high curing speed, high adhesion power, high deflocculation performance, high surface hardness, long service life and the like.

Description

technical field [0001] The invention belongs to the low-carbon green industry, and in particular relates to an environment-friendly and powerful liquid material for room temperature asphalt pavement and a preparation method thereof. Background technique [0002] At present, due to the defects and singleness of the dispersed phase structure of modified emulsified asphalt and water-based polymer emulsion at home and abroad, environmental protection road bridges and building room temperature materials cannot meet the diverse and comprehensive requirements. Although domestic water-based resin products are not uncommon, their quality is not stable, and there are few products suitable for comprehensive applications. A considerable part of the water-based products developed by them have been proved by some domestic manufacturers, and their late-stage adhesion performance is insufficient, so these products are not yet available. It is widely used in road and bridge, cement construct...
