Embodiment Construction

[0024] As shown in the figure, the waste tire rubber powder plant asphalt material and its preparation method first take 50% of petroleum asphalt, 35% of plant asphalt, 25% of waste tire rubber powder, 3% of talcum powder, and 6% of base oil, and then mix the petroleum asphalt After heating with plant asphalt, mix in proportion, add talcum powder and waste tire rubber powder, stir evenly, add aromatic oil, mix evenly under high temperature conditions of 150°C, and react for 120 minutes to prepare asphalt Material.

[0025] After the petroleum asphalt and vegetable asphalt are heated to 120°C, mix and stir evenly, or put the bagged vegetable asphalt directly into the petroleum asphalt heating tank, stir evenly and heat to above 150°C, the mixture of the two kinds of asphalt after heating enters At the same time, waste tire rubber powder and talcum powder also enter the premix tank successively. Several materials are quickly dispersed and mixed under the action of a high-speed a...

Abstract

The invention relates to the technical field of production and construction materials, and especially relates to a preparation method of modified asphalt produced under a certain condition by using waste residue produced during grain processing, waste tire rubber powder, petroleum asphalt, and other auxiliary materials. The material comprises 40-60% of petroleum asphalt, 25-50% of plant asphalt, 5-30% of waste tire rubber powder, 1 to 5% talcum powder, and 2-10% of base oil. The preparation method comprises the steps that: petroleum asphalt and plant asphalt are heated and are mixed according to the ratio; talcum powder (or cement and calcium powder) and waste tire rubber powder are added at the same time; the mixture is well mixed, and aromatic oil is added (the aromatic oil can also be added before the rubber powder and the talcum powder); the mixture is uniformly mixed and blended under a high-temperature condition; and reaction and development are carried out for 30-240min, such that the asphalt material is prepared. The asphalt material can be widely used in various levels of pavement for replacing other asphalt materials. With the asphalt material provided by the invention, pavement application performance is improved, petroleum resource is saved, environment is protected, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of production of building materials, in particular to a method for preparing modified asphalt produced under certain conditions using waste residue (also known as plant asphalt), waste tire rubber powder, petroleum asphalt and other additives produced in the deep processing of grain . Background technique [0002] As a by-product of the petroleum refining process, petroleum asphalt is widely used in road engineering. With the depletion of petroleum resources, road petroleum asphalt is increasingly in short supply, and the price is increasing year by year. It is urgent to find cost-effective alternatives. [0003] Vegetable asphalt is the material extracted from the residual residue after refining sugar or oil production from grain. It mostly exists in semi-solid or solid form at room temperature. It can also be used as plant asphalt. There are currently two main sources of plant asphalt: one is to use veget...
