Abstract
The invention discloses an environment-friendly preparation process of a warm-mix asphalt cement material. By adopting the technical formula (w/%), the environment-friendly preparation process comprises the following components: 80%-90% of an asphalt cement material, 2%-18% of a recycled material, 0.5%-5% of sodium polyphosphate and 0.05%-2% of water. The warm-mix asphalt cement material prepared by the preparation process still keeps good liquidity at a relatively low temperature due to the action of a sodium polyphosphate water solution, thus the stirring, paving and storing temperatures of the asphalt cement material are lowered. By introducing a proper amount of water, the viscosity of the asphalt is effectively reduced; meanwhile, gasification and volatilization of organic matters are reduced; the safety of the environment and a human body is protected; recycled plastic and recycled rubber are effectively utilized, so that the problem of plastic pollution is greatly solved; the warm-mix asphalt cement material prepared by the environment-friendly preparation process is stable in property, safe and environment-friendly; and the preparation process is simple and easy to control.
Description
Technical field
The present invention relates to a kind of Warm mixed asphalt cement, particularly a kind of environment-friendly preparation process of Warm mixed asphalt cement, belongs to petrochemical industry.
Background technology
Bituminous pavement, as a kind of continuous pavement, has damping, an advantage such as comfortable, the easy-maintaining of driving a vehicle, and is the major way that high class pavement adopts.Along with the quickening of industrialization, urbanization process, there is great demand to the usage quantity of bituminous cements.Generally use the hard pitch higher than 200 DEG C directly to carry out cooling forming through sieve plate distributor in existing refining of petroleum industry, but there is mixing, transport and in the process that paves, occur thermal ageing, toxic gaseous emission and too much energy consumption problem in hard pitch.Along with the cry of global energy-saving and emission-reduction is surging, scientific workers have made a large amount of effort in the temperature reducing mixing bituminous cements and environmental protection, environmentally friendly Warm-Mix Bitumen Mixture is come out one after another with kinds of processes form, and gets up in ground widespread uses such as Europe, North America, South Africa, East Asia.
" Warm mixed asphalt cement and preparation method thereof " disclosed in CN 201010609465, adds rheological modifiers and high molecular polymer and carries out hybrid reaction and obtain in bituminous cements; " a kind of Warm-Mix Bitumen Mixture and preparation method thereof " disclosed in CN 101302348A adopts Sasobit warm-mixed asphalt additive to carry out warm mix, adopt cracking polyethylene wax and stearic acid as smoke inhibition modifying agent in CN 101649122 disclosed " a kind of SBS modifying asphalt and preparation method thereof ", modification is carried out to SBS modifying asphalt agglutinate, in WO2009137299A2 disclosed " resin modified bituminous cements component ", in bituminous cements, add the resin of 0.01wt% ~ 25wt%.Above-mentioned patent documentation all solves cooling viscosity reduction problem when asphalt mixes and stirs, and improves construction workability, strengthens compactness.In addition in US 006846354B2 disclosed " technique of production warm mix plate form rubber composition and system ", appropriate moisture is introduced in bituminous cements, make pitch by foaming viscosity reduction, realize the warm mix of asphalt preferably, reach the object of energy-saving and emission-reduction.
Plastics are widely used in packaging, furniture, plastic film for agricultural use, Industrial materials because it has good shaping, the feature such as insulativity, acid and alkali-resistance, erosion resistance by people.But increase along with plastics output, price reduces, and renewal frequency is accelerated, and makes plastic products also increasing to the pollution of environment, " white pollution " that waste plastic brings, and having become one today can not unheeded social effects of pollution again.China is one of ten large plastics production and consumption states in the world, the recycling of plastic products in recent years also result in the great attention of country and society, greatly develop plastics recycling industry and not only slow down environmental pollution, facilitate again the fast development of plastic industry.
Current, for the rare report of research and development recycled plastic is applied in bituminous cements.
We study by experiment, by recycled plastic or rubber applications in bituminous cements, develop a kind of environment-friendly preparation process of Warm mixed asphalt cement.
Summary of the invention
Goal of the invention: for the problems of the prior art, a large amount of plastics that the present invention reclaims in being intended to utilize life to produce or rubber item, provide a kind of production technique simple, the environment-friendly preparation process of the Warm mixed asphalt cement that product property is stable.
For achieving the above object, the present invention by the following technical solutions: a kind of environment-friendly preparation process of Warm mixed asphalt cement, comprises the steps:
A, weigh each material component by proportioning; B, by bituminous cements heating raw materials to 130 ~ 160 DEG C, make its progressively softening melting; C, the reclaimed materials of weighing to be pulverized; D, the crushed material of step C is added in the molten mass of step B, be stirred to evenly; E, maintenance temperature 130 ~ 160 DEG C, add sodium polyphosphate and water, shear, stir, be slowly warming up to 140 ~ 175 DEG C in the melting mixing body of step D gained, continues stirring reaction and take the dish out of the pot for 0.5 ~ 2 hour; The ratio of described each raw material following (
w/ %):
Bituminous cements 80 ~ 90
Reclaimed materials 2 ~ 18
Sodium polyphosphate 0.5 ~ 5
Water 0.05 ~ 2.
As preferably, described bituminous cements is reason pitch or the polymer modified asphalt of each class requirement in satisfied " standard specification for construction and acceptance of highway asphalt pavement " (JTG F40-2004).
As preferably, described reclaimed materials is a kind of in plastics, rubber or both mixtures.
As preferably, described plastics are homogeneous plastic or heterogeneous plastics.
As preferably, described rubber is homogeneity rubber or heterogeneous rubber.
The environment-friendly preparation process of a kind of Warm mixed asphalt cement provided by the invention, compared to existing technology, there is following beneficial effect: the Warm mixed asphalt cement prepared by the present invention is due to the effect of polyphosphoric acid sodium water solution, still good mobility is kept at a lower temperature, thus reduce bituminous cements stirring, pave storing temp; Introduce appropriate water in the present invention, while making the effective viscosity reduction of pitch, reduce organic gasification volatilization, protection of the environment and human-body safety; Effective utilization of recycled plastic and recovery rubber, very big limit solves white pollution problems; The made Warm mixed asphalt cement stable in properties of the present invention, safety and environmental protection, production technique is simple and easy to control.
