preparation example Construction

[0033] The embodiment of the present invention also discloses a preparation method of the anti-rutting modifier. The method specifically includes the following steps:

[0034] Step S10: weighing raw materials.

[0035] The raw materials include the following components in parts by weight: 40-80 parts of polyolefin recycled material, 10-30 parts of tire rubber powder, 20-50 parts of toughening modifier, 0-5 parts of inorganic filler, coupling agent 0.5-2 parts and antioxidant 0.1-1 part.

[0036] Step S20: Mix the raw materials uniformly to obtain a first mixture.

[0037] Preferably, the mixing temperature in step S20 is 50-100°C. The mixing temperature facilitates uniform dispersion of the blend. The mixing process can be carried out in a high speed mixer. More preferably, the raw materials are stirred in a high-speed mixer for 5-10 minutes, so as to mix the raw materials uniformly.

[0038] Step S30 : the first mixture is extruded after being melt-kneaded, cooled and d...

Embodiment 1

[0046] 50 parts of high-density polyethylene recycled material, 10 parts of tire rubber powder (40 mesh), 25 parts of chlorinated polyethylene, 12 parts of styrene-acrylonitrile copolymer, 3 parts of talc, titanate coupling agent (TMC -201) 0.5 parts, antioxidant (1010) 0.2 parts, antioxidant (168) 0.3 parts in a high-speed mixer at 50 ℃ high-speed stirring for 10min, and then sent to a twin-screw extruder for extrusion granulation, machine The barrel temperature was 160° C., and the screw speed was 180 r / min to obtain anti-rutting modifier 1#.

Embodiment 2

[0048] 45 parts of polypropylene recycled material, 12 parts of tire rubber powder (40 mesh), 8 parts of polymethyl methacrylate, 30 parts of styrene-butadiene-styrene block copolymer, 3 parts of ultrafine calcium carbonate, 0.5 part of titanate coupling agent (TMC-201), 0.2 part of antioxidant (1076), 0.3 part of antioxidant (168) in a high-speed mixer at 60℃ for 10min, and then sent to twin-screw extrusion Extrusion and granulation in the machine, the barrel temperature is 200 ℃, the screw speed is 400 r / min, and the anti-rutting modifier 2# is obtained.

Abstract

The embodiment of the invention discloses an anti-rutting modifier which is prepared from the following components in parts by weight: 40-80 parts of recycled polyolefin, 10-30 parts of tire rubber powder, 20-50 parts of a toughening modifier, 0-5 parts of inorganic packing, 0.5-2 parts of a coupling agent and 0.1-1 part of an antioxidant. The embodiment of the invention further provides a preparation method and application of the anti-rutting modifier in asphalt. The anti-rutting modifier disclosed by the embodiment of the invention is relatively high in strength and toughness, and after the anti-rutting modifier is mixed with asphalt, the strength of an asphalt mixed material can be improved, the toughness of the asphalt mixed material can be also greatly improved, and the high-temperature anti-rutting property, the low-temperature cracking resistance and the fatigue resistance of the asphalt mixed material can be improved.

Description

technical field [0001] The invention relates to the technical field of anti-rutting modifiers, in particular to an anti-rutting modifier, a preparation method and applications thereof. Background technique [0002] Asphalt pavement has been widely used as the main structure type of high-grade highway due to its excellent performance. However, in recent years, with the increasing traffic load and the influence of climatic conditions, the asphalt pavement is undergoing severe tests, especially in the high temperature in summer, the asphalt surface layer produces viscous flow and permanent deformation under the repeated rolling action of vehicles, forming ruts . As one of the main damage forms of asphalt pavement in my country, rutting disease not only affects the driving comfort and safety, but also further induces other diseases and seriously shortens the service life of the pavement. [0003] In view of the rutting disease of asphalt pavement, European scholars have develo...
