Asphalt pavement protective film resistant to ultraviolet aging and spraying method

Abstract

The invention discloses an asphalt pavement protective film resistant to ultraviolet aging and spraying method. The asphalt pavement protective film is prepared from the following materials in parts by weight: 2 to 3 parts of nano titanium dioxide, 10 to 15 parts of silicon oxide, 5 to 10 parts of a modified asphalt anti-aging agent, 40 to 50 parts of epoxy resin, 5 to 10 parts of waterborne acrylic emulsion, 0.5 to 2 parts of propylene glycol butyl ether, 0.5 to 1.5 parts of a dispersion, 0.8 to 0.9 part of a dispersing agent, 0.1 to 0.2 part of a defoaming agent, 0.1 to 0.5 part of a flatting agent, 15 to 20 parts of an organic solvent and 20 to 25 parts of deionized water. According to the asphalt pavement protective film resistant to ultraviolet aging and the spraying method, the coating can effectively prevent ultraviolet rays, the use performance of an asphalt pavement is improved, the service life of the asphalt pavement is prolonged, the added silicon oxide enables the coating to have high wear resistance, the contained nano titanium dioxide can effectively catalyze and decompose toxic gas discharged by automobiles, and meanwhile, the coating also has the effects of cold resistance and skid resistance.

Description

technical field [0001] The invention relates to the technical field of road building materials, in particular to an anti-ultraviolet aging asphalt pavement protective film and a spraying method. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the pavement smooth and less dusty. Permeable and durable, asphalt pavement is the most widely used high-grade pavement in road construction. [0003] Asphalt pavement in high-cold and high-altitude areas is prone to aging under the action of the natural environment, causing problems such as cracking and loosening. Cause the generation of traffic accident; Meanwhile, the anti-ultraviolet aging measures of asphalt pavement mainly modify asphalt at present, promptly add ultraviolet shielding agent and absorber in asphalt, but t...
