Abstract
The invention discloses road modified asphalt. The modified asphalt is prepared from the following raw materials in parts by weight: 100-120 parts of asphalt, 20-30 parts of polyurethane, 15-22 parts of rubber powder, 10-16 parts of stearic acid, 0.5-1.5 parts of nano aluminum oxide, 0.5-0.8 part of Arabic gum, 5-11 parts of magnesium silicate, 5-11 parts of lauryl alcohol polyoxyethylene sodium sulfate, 10-16 parts of acetone, 3-6 parts of glass fibers, 0.5-1.5 parts of dimethyl phthalate, 0.5-1.4 parts of phenol, 4-10 parts of rosin and 2-6 parts of an anti-ageing agent. According to the road modified asphalt disclosed by the invention, the viscosity and the ageing resistance of the asphalt are improved by adding the polyurethane, the rubber powder, the stearic acid, the nano aluminum oxide, the Arabic gum, the magnesium silicate, the lauryl alcohol polyoxyethylene sodium sulfate, the acetone, the glass fibers, the dimethyl phthalate, the phenol and the anti-ageing agent, so that the road modified asphalt is suitable for being used on a road, and the service life of the road can be prolonged.
Description
Technical field:
The present invention relates to a kind of road modified asphalt, belong to industrial chemical field.
Background technology:
The chocolate complex mixture that pitch is made up of hydrocarbon polymer and the nonmetal derivative thereof of different molecular weight, is the one of high viscosity organic liquid, is in a liquid state, and surface, in black, dissolves in dithiocarbonic anhydride.Pitch is a kind of waterproof and dampproof and rot-resistant organic gel gel material.Pitch mainly can be divided into coal tar pitch, petroleum pitch and rock asphalt three kinds: wherein, and coal tar pitch is the byproduct of coking.Petroleum pitch is the residue after crude distillation.Rock asphalt is then be stored at underground, some formation ore beds or at earth's crust surface sediment.Pitch is mainly used in industry and the surfacings etc. such as coating, plastics, rubber.
Since reform and opening-up, the economy of China remains growth at a high speed always, and Construction of Highway Traffic is advanced by leaps and bounds, and road bitumen manufacturing enterprise of China have also been obtained fast development.Especially heavy traffic paving asphalt and modifying asphalt achieve by without to having, ascending, qualitative leap from less to more, for tremendous contribution has been made in China's Road construction.Wherein, come maintenance road surface with pitch and be usually divided into three types: preventive maintenance, corrective maintenance, should acute maintenance.These three kinds of maintenance patterns can be selected according to the service condition on road surface, and each maintenance pattern needs again to select different maintenance processes and maintenance of equipment.
But high-end modifying asphalt is still little, can not meet ever-increasing professional Asphalt market demand.
Summary of the invention:
The present invention seeks to, be used for making up the deficiencies in the prior art, and a kind of road modified asphalt is provided.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of road modified asphalt, is made up of the raw material of following parts by weight: pitch 100-120 part, urethane 20-30 part, rubber powder 15-22 part, stearic acid 10-16 part, nano aluminium oxide 0.5-1.5 part, gum arabic 0.5-0.8 part, Magnesium Silicate q-agent 5-11 part, ethoxylated dodecyl alcohol sodium sulfate 5-11 part, acetone 10-16 part, glass fibre 3-6 part, dimethyl phthalate 0.5-1.5 part, phenol 0.5-1.4 part, rosin 4-10 part and anti-aging agent 2-6 part.
