Abstract

The present invention discloses a color asphalt and its preparation method. Its composite includes petroleum asphalt 90# 40-44%, petroleum resin 120# 26-30%, petroleum resin 90# 3-5%, extractive oil 4-6%, xylene 2-4%, santobrite salt 5-7%, 99% chromium 2-4%, iron oxide 30# 3-5%, rosen 3-4% and titanium oxide 1-3% and proper quantity of pigment. Said invention adopts the following processes: reduced pressure distillation for extracting asphaltene, splitting by splitter tower, adding resin material, titanium and pigment, then making high-temp. synthesis. It is a new type builidng material, can be used for laying pavement, etc.

Description

Technical field: [0001] The invention belongs to new building materials, in particular to a kind of colored asphalt, and also relates to a preparation method of the colored asphalt. Background technique: [0002] Traditional paving at home and abroad generally adopts black asphalt pavement. This kind of pavement is made of a certain proportion of black asphalt, sand and gravel aggregates and stone powder, which are mixed into black asphalt mixture through an asphalt mixer, and the pavement is rolled and formed. This kind of pavement has a single tone and is called "black pavement". With the development of the economy and the improvement of people's requirements for the living environment, the "colored pavement" paved with colored asphalt and matched with the natural environment is gradually replacing the traditional "black pavement". Yellow, green and other certain color pigments are formulated. The traditional production technology of decolorized asphalt is: remove the bl...
