Embodiment 1

[0027] Composite modified asphalt raw materials: 100 parts of asphalt, 6 parts of spodumene powder, 2 parts of boron carbide powder, 0.9 part of 3-(methacryloyloxy)propyltrimethoxysilane, 0.4 part of dibutyltin diacetate, 3 parts of flame retardant , 0.45 parts of dispersant.

[0028] The flame retardant is obtained by uniformly stirring and mixing aluminum diethylphosphate, aluminum methylpropionate and aluminum 2-carboxyethylphenylphosphinate in a mass ratio of 1:1:1.

[0029] The dispersant is obtained by stirring and mixing sodium pyrophosphate, potassium tripolyphosphate and sodium stearate uniformly in a mass ratio of 1:1:1.

[0030] Preparation method of composite modified asphalt:

[0031] Heat the asphalt to a temperature of 180°C and completely melt, add dibutyltin diacetate and keep the temperature at 180°C under a high-speed shearing machine, shear for 10 minutes, and the shearing speed is 4000 rpm, then add spodumene powder, carbonize Boron powder, 3-(methacrylo...

Embodiment 2

[0033] It is basically the same as Example 1, the only difference is that the flame retardant is obtained by stirring and mixing aluminum methionyl phosphinate and aluminum 2-carboxyethylphenyl phosphinate in a mass ratio of 1:1 .

Embodiment 3

[0035] It is basically the same as in Example 1, except that the flame retardant is obtained by stirring and mixing uniformly diethylaluminum phosphate and 2-carboxyethylphenylaluminum phosphinate at a mass ratio of 1:1.

Abstract

The invention discloses a composite modified asphalt. The composite modified asphalt is prepared from, by weight, 95 to 105 parts of asphalt, 2 to 9 parts of spodumene powder, 1 to 10 parts of boron carbide powder, 0.5 to 1.5 parts of 3-(isobutylene acyloxy)propyltrimethoxysilane, 0.1 to 1 part of dibutyltin diacetate, 1 to 5 parts of a fire retardant, and 0.2 to 0.9 part of a dispersant. The composite modified asphalt is capable of satisfying requirements on asphalt road using performance, possesses excellent heat mixing emission reduction effect, the release amount of glance coal in blendingprocess can be reduced effectively, construction environment can be improved, and excellent economical and social benefit is achieved.

Description

technical field [0001] The invention relates to the technical field of asphalt modification, in particular to composite modified asphalt. Background technique [0002] With the rapid development of highway construction in our country, while the mileage of highways has increased rapidly year by year, the traffic flow and heavy-duty vehicles on the highways have increased rapidly, and the wear and tear of the road surfaces has greatly increased compared with before. It has become urgent to improve the quality of the road surface and prolong the service life of the highway. Especially in summer or in some areas prone to high temperature and rainy weather, the viscosity of the road surface will be greatly reduced, and the passage of traffic will easily damage the road. [0003] Bitumen is a material commonly used in the preparation of paving and roofing materials. In the road-building and road-laying industries, it is a well-established and practical method to coat aggregate ma...
