Abstract
The invention relates to the technical field of modifiers, and in particular relates to a road asphalt modifier. The road asphalt modifier comprises the following components by weight: 30 to 80 parts of waste rubber powder, 5 to 20 parts of dispersing agent, 5 to 10 parts of cross-linking agent, and 5 to 10 parts of adhesion agent. The road asphalt modifier has the beneficial effects that the natures of the asphalt on softening point, needle penetration, viscosity and ductility are greatly improved; and the waste rubber serves as the raw material of the modifier, so that the purpose of turning waste into treasure is achieved, the waste rubber can be comprehensively utilized, and the damage of the waste rubber to the environment can be reduced, and as a result, the environment is protected.
Description
Technical field:
The invention belongs to the technical field of properties-correcting agent, relate in particular to a kind of road asphalt modifier.
Background technology:
Pitch occupies very important status in road construction, it directly affects the usability of highway and durable.But the pitch of domestic production is owing to the impact of oil property and refining technology, and wax content is higher, and the road is relatively poor with property, is difficult to satisfy the requirement of high-grade highway construction.The pavement performance that uses properties-correcting agent to improve pitch becomes one of novel method of producing high-grade highway pitch.
For the research of asphalt modifier, people do a lot of work.For example, CN1424358A has described a kind of properties-correcting agent that utilizes the raw material preparations such as coal and catalytically cracked oil.This properties-correcting agent has improved some performance of pitch to a certain extent, but this properties-correcting agent needs the conditions such as high pressure-temperature in the preparation method.And for example CN1354221A has described a kind of quadrol, formaldehyde, enanthic acid and phenyl aldehyde of utilizing and has been raw material, asphalt modifier through amine aldehyde, amino acid condensation preparation, this properties-correcting agent has improved the character such as the resistance to deterioration, adhesivity of pitch to a certain extent, but at the softening temperature that improves pitch, improve the low temperature flexibility of pitch, reduce penetration degree, the aspects such as raising ductility all do not have too large effect.
For the shortcoming that in the market asphalt modifier exists, the invention provides a kind of asphalt modifier that utilizes the waste rubber preparation and preparation method thereof.The indexs such as its softening temperature of pitch, low temperature flexibility, ductility and adhesivity of adding this properties-correcting agent have all reached JTJ032-94 and TJ052-2000.In addition, the preparation method of this properties-correcting agent is simple, simultaneously also can in addition recycle of waste rubber, play to a great extent environmental-protection function.
Summary of the invention
The present invention seeks to a kind of asphalt modifier of preparing for the shortcoming that solves existing asphalt modifier on the market.This properties-correcting agent can improve pitch to a great extent in the character of softening temperature, penetration degree, viscosity and ductility.And, because the used raw material of this properties-correcting agent is waste rubber, so aspect utilization of waste material, also be significant.
Technical scheme of the present invention: asphalt modifier of the present invention is comprised of the following component of counting by weight:
Waste Crumb rubber 30-80 part, dispersion agent 5-20 part, linking agent 5-10 part, interfacial agents 5-10 part.
The granularity of above-mentioned waste Crumb rubber is the 60-100 order.
Above-mentioned dispersion agent is any one in maleinamide, hexenyl bis-stearamides, the glyceryl monostearate.
Above-mentioned dispersion agent is glyceryl monostearate.
Above-mentioned linking agent is dicumyl peroxide or 2,5-dimethyl-2,5 di-t-butyl hexane peroxide.
Above-mentioned linking agent is dicumyl peroxide.
Above-mentioned interfacial agents is bisphenol A epoxide resin.
The preparation method of above-mentioned a kind of road asphalt modifier is: it is 60-100 purpose waste Crumb rubber that waste Crumb rubber is broken to granularity, takes by weighing 30-80 part, and with dispersion agent 5-20 part, linking agent 5-10 part, interfacial agents 5-10 part mixes, the packing and get final product.
The preparation method of above-mentioned a kind of road asphalt modifier is: say that it is 80 purpose waste Crumb rubbers that waste Crumb rubber is broken to granularity, take by weighing 50 parts, and with 15 parts of glyceryl monostearates, 8 parts of dicumyl peroxides, 8 parts of bisphenol A epoxide resins mix, the packing and get final product.The using method of above-mentioned asphalt modifier: matrix pitch is heated to 170-180 ℃, add while stirring the asphalt modifier that has prepared according to formula rate, use high-shear emulsion machine with 7000 r/min speed shear agitation 30min after preliminary the mixing, can make the modifying asphalt sample.
The invention has the beneficial effects as follows: the present invention has not only improved the character of pitch in softening temperature, penetration degree, viscosity and ductility to a great extent; and; because the used raw material of this properties-correcting agent is waste rubber; turn waste into wealth; realized the comprehensive utilization of waste rubber; reduce waste rubber environment has been brought harm, protected environment.
