Abstract
The invention belongs to the technical field of asphalt additives and particularly relates to an additive for enhancing the road asphalt ductility. The additive consists of the following components in parts by weight: 40-80 parts of epoxy resin, 10-30 parts of dispersing agent and 10-30 parts of adhesion agent. The additive provided by the invention has the following beneficial effects: by virtue of adding the additive, the road asphalt ductility can be effectively enhanced and the blank for enhancing the road asphalt ductility is filled; and the preparation method is simple and the use is convenient.
Description
Technical field:
The invention belongs to the technical field of the additive of pitch, relate in particular to a kind of additive for improving the road bitumen ductility.
Background technology:
Modifying asphalt has had the history in more than 60 year since being born in Europe in 1940, in order to satisfy the needs of various pavement performances, various countries are devoted to the research of modifying asphalt one after another.So-called modifying asphalt refers to add a certain amount of properties-correcting agent in plain asphalt (claiming again matrix pitch), and the performances such as temperature sensibility, stability, resistance to deterioration of pitch are improved, thus the use properties of raising pitch.
Pitch is made 8 font standard specimens, and under 25 ° of C temperature, the length (cm) when being stretched to fracture with 5cm per minute speed is ductility.Ductility is larger, shows that the plasticity of pitch is better.Ductility is the important indicator of evaluation pitch plasticity.In order to improve the ductility of pitch, added the ductility agent in the past in the pitch and improved its ductility.The higher material of horizon suppleness in the pitch for example, so, the epoxy that snappiness is higher just expected by people, but at present epoxy but rarely had report for increasing the research of bitumen ductility.
For additive of seeking to the invention provides a kind of novel increase bitumen ductility and preparation method thereof.Additive provided by the invention can improve the ductility of pitch to a great extent.
Summary of the invention
The present invention is a kind of additive for improving the road bitumen ductility of inventing in order to improve bitumen ductility, adopt this additive after, the ductility of road bitumen significantly increases.
Technical scheme of the present invention: a kind of additive for improving the road bitumen ductility is comprised of the following component of counting by weight: Resins, epoxy 40-80 part; Dispersion agent 10-30 part; Interfacial agents 10-30 part.
Above-mentioned Resins, epoxy is polybutadiene epoxy resin or ethylene oxidic ester epoxy resin, and preferred Resins, epoxy is polybutadiene epoxy resin.
Above-mentioned dispersion agent is any one in guar gum, polyacrylamide, the sodium lauryl sulphate, and preferred dispersion agent is polyacrylamide.
Above-mentioned interfacial agents is vinyl acetate-ethylene copolymerization emulsions or ACRYLIC EMULSION, and preferred interfacial agents is vinyl acetate-ethylene copolymerization emulsions.
The preparation method of above-mentioned a kind of additive for improving the road bitumen ductility is: take by weighing respectively 40-80 part Resins, epoxy, 10-30 part dispersion agent, 10-30 part interfacial agents and mix, packing and get final product.
The preparation method of above-mentioned a kind of additive for improving the road bitumen ductility is: take by weighing respectively 50 parts of Resins, epoxy, 25 parts of dispersion agents, 20 parts of interfacial agents and mix, packing and get final product.
