Ommt modified anti-icing emulsified asphalt and preparation method

Abstract

The invention discloses an OMMT-modified anti-icing emulsified asphalt. The formula of the OMMT-modified anti-icing emulsified asphalt comprises: 40-50 parts of machine montmorillonite, 10 parts of modifier ‑15 parts, 5‑10 parts of emulsifier, 80‑120 parts of base asphalt, 300‑430 parts of deionized water, 5‑11 parts of benzoyl peroxide and 4‑10 parts of stabilizer; the preparation device provided by this program uses At the same time, the asphalt is transported to the feed box inside the heating box through the feed pipe, and is connected to the heat transfer oil pipeline through the oil inlet pipe. The heat pipe and the material storage box, together with the heating plate, can quickly heat and soften the asphalt and transport it to the mixing tank through the first water pump, so as to make the asphalt soften quickly and speed up the delivery efficiency in the asphalt preparation, and the softened asphalt and the prepared solution are respectively transported to the inside of the mixing tank , Stir and mix the softened asphalt and the prepared solution.

Description

technical field [0001] The invention relates to the technical field of asphalt production, in particular, to OMMT-modified anti-coagulation ice emulsified asphalt and OMMT-modified anti-coagulation ice emulsified asphalt, and in particular to a preparation method of OMMT-modified anti-coagulation ice emulsified asphalt. Preparation device. Background technique [0002] As we all know, asphalt is a complex mixture of black and brown composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. Soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof and anti-corrosion organic cementitious material. Among them, modified asphalt is mixed with modifiers such as rubber, resin, macromolecular polymer, finely ground rubber powder or other fillers, or it is treated with mild asphalt. Oxidative processing and other measures can improve the performance of asphalt or asph...

AI Technical Summary

Problems solved by technology

[0003] 1. The mixing, stirring and emulsifying treatment in the prior art cannot quickly soften the asphalt when conveying and putting in the asphalt, which leads to a great reduction in the conveying and mixing efficiency of the asphalt;

[0004] 2. When the bitumen in the prior art is mixed and stirred with the prepared solution, it is often impossible to monitor and control the temperature of the bitumen and the humidity of the mixture, resulting in insufficient yield of bitumen after treatment, thereby increasing the preparation cost;

[0005] 3. The rheological properties of the modified emulsified asphalt in the prior art and the environmental resistance at high or low temperatures are insufficient, resulting in easy softening, deformation or cracking in different environments, and prone to bonding failure or aging.
