Problems solved by technology

Although the existing modified asphalt overcomes many shortcomings of pure asphalt and greatly increases the use range of asphalt, the price is generally high, and most of the modified asphalt only considers how to make the product have better performance. Seldom consider how to make better use of waste and protect the environment

Embodiment 1

[0014] formula:

[0015] 10# construction petroleum asphalt 3.4kg old tire rubber 0.7kg

[0016] Waste lubricating oil 0.5kg Raw varnish 0.15kg

[0017] Tung oil 0.15kg Turpentine 0.25kg

[0018] Preparation:

[0019] The old tire rubber is cut into small pieces of about 2cm to 3cm in size. The waste lubricating oil is filtered by sedimentation, put into the pot together with raw lacquer, tung oil, and turpentine oil, and stirred while heating. Heating to about 300°C, the waste tire rubber is completely melted, Stop heating, add turpentine when the temperature is naturally lowered to about 150°C, and stir evenly to obtain a finished product. The three quality indicators of finished products are:

[0020] Penetration (25℃ 100g 1 / 10mm) 74

[0021] Ductility (25℃ cm) ≥100

[0022] Softening point (℃) 53

Embodiment 2

[0024] formula:

[0025] 10# construction petroleum asphalt 2.75kg old tire rubber 1.15kg

[0026] Waste lubricating oil 0.9kg Raw varnish 0.05kg

[0027] Tung oil 0.05kg Turpentine 0.1kg

[0028] The preparation method is the same as in Example 1. The three quality indicators of finished products are:

[0029] Penetration (25℃ 100g 1 / 10mm) 88

[0030] Ductility (25℃ cm) ≥100

[0031] Softening point (℃) 49

Embodiment 3

[0033] formula:

[0034] 10# construction petroleum asphalt 2.25kg old tire rubber 1.5kg

[0035] Waste lubricating oil 1.15kg Raw varnish 0.025kg

[0036] Tung oil 0.025kg Turpentine 0.05kg

[0037] The preparation method is the same as in Example 1. The three quality indicators of finished products are:

[0038] Penetration (25℃100g 1 / 10mm) 107

[0039] Ductility (25℃ cm) ≥100

[0040] Softening point (℃) 45

Abstract

The environment protecting modified pitch has material comprising 10#-60# petroleum pitch 45-70 wt%, waste tyre rubber 12-35 wt%, waste lubricating oil 10-25 wt%, raw lacquer 0.5-3 wt%, tung oil 0.5-3 wt% and turpentine 1-5 wt%. The modified pitch may be used as filleting material for road and cement and concrete structures, waterproof material in roof, underground engineering, warehouse, etc. With partial waste in its material, the present invention has lowered cost and is environment friendly.

Description

technical field [0001] The present invention relates to the building material bitumen. Background technique [0002] Asphalt is widely used. In addition to being used for waterproofing and other occasions, asphalt required for road construction accounts for a large part of all asphalt consumption. However, pure construction petroleum asphalt has many shortcomings, such as easy aging, poor water stripping resistance, and poor low temperature cracking resistance. The penetration and ductility of construction 10# petroleum asphalt are very low, but the softening value is very high. At present, many modified asphalts have appeared, among which the most common ones are modified asphalts produced by adding raw materials such as rubber and resin. Although the existing modified asphalt overcomes many shortcomings of pure asphalt and greatly increases the use range of asphalt, the price is generally high, and most of the modified asphalt only considers how...
