Description
Technical field
The present invention relates to the road engineering materials used, especially a kind of heat reflection coating for bituminous pavement.
Background technology
Bituminous pavement has advantages such as planeness height, comfortableness is good, noise is low, and in the Road construction of China, bituminous pavement is just used more and more widely.But the most of visible light in the bituminous pavement absorption sunlight and the infrared part of invisible light cause pavement temperature to raise, road surface continuous release of heat circumference atmosphere, thus aggravated urban heat land effect; Simultaneously, the pyritous bituminous pavement also discharges a large amount of pitch volatile matters, makes human settlement's rapid deterioration.The problem that how to keep the good characteristic of bituminous pavement but reduce its surface temperature simultaneously needs to be resolved hurrily.The falling temperature technique of body surface can be traced back to eighties of last century.Phase later 1970s, fast-developing Building technology makes radiative cooling and reflective isolating technology that huge development arranged, and states such as the U.S., Japan, West Europe begin to carry out the development of solar heat reflection paint for building.China since the nineties in 20th century also the research of solar heat reflection paint.US5445754 discloses a kind of good water-borne heat-insulating coating of heat-proof quality that adopts dibutyl maleinate-vinyl acetate copolymer and ceramic Si132 pearly-lustre insulation agent to prepare; It is that membrane-forming agent adds the high temperature heat transfer pipe of functional filler preparation or the heat-resisting sun-proof coating that the application of flue steel material surface is used that JP9071874 discloses a kind of acrylic resin; CN1405248 discloses the heat reflection coatings that a kind of acrylic resin, titanium dioxide etc. are formed, and this material can be widely used in fields such as petrochemical industry storage tank, grain depot, house, car and boat.
Heat reflection coatings still is mainly used in the heat insulation of building, oil storage (gas) jar at present, and the aspects such as cooling on aircraft deck.Because road surface is subjected to effects such as traffic load, friction, the solar heat reflection coating is removed and is satisfied basic heat reflectivity, ageing resistance, also must possess high-wearing feature and good characteristics such as snappiness under strong loading action.
Summary of the invention
Thinking of the present invention is a kind of heat reflection coating for bituminous pavement of preparation, the highly reflective filler has high-reflectivity in this coating, make acrylic acid or the like reacting resin fast setting at normal temperatures by adding promotor and solidifying agent simultaneously, its heat cured characteristic promptly provides the high-wearing feature of coating.It is coated the bituminous pavement surface can effectively reduce by 10～20 ℃ of pavement temperatures at summer high temperature during season, thereby reduces road surface thermostability disease and alleviating urban heat island effect.
But the purpose of this invention is to provide a kind ofly have that heat reflectivity is strong, wear resistance and snappiness is good and the quick-setting heat reflection coating for bituminous pavement of normal temperature.
The object of the present invention is achieved like this: by A part acrylic class reacting resin, high reflection filler, pigment, oxygenant, softening agent, solvent, anti-settling agent, B component solidifying agent is formed, and its component is by weight measuring:
A component: 100 parts of acrylic acid or the like reacting resins
5～30 parts of high reflection fillers
0.2～5 part of pigment
0.2～5 part of promotor
0.5～5 part in softening agent
2～10 parts of solvents
0.5～5 part of anti-settling agent
B component: solidifying agent
By mass ratio 100: 0.1～5 A, B component are mixed, stir, promptly get heat reflection coating for bituminous pavement.
Acrylic acid or the like reacting resin of the present invention is acrylic acid modified alkyd resin, acrylic acid modified polyester resin, and component is measured one or both mixtures of 0～100 part of acrylic acid modified alkyd resin, 0～100 part of acrylic acid modified polyester resin by weight.Two kinds of compositions can not be zero simultaneously.
High reflection filler of the present invention is one or more mixtures of titanium dioxide, barium sulfate, zinc oxide, and component is measured 0～100 part of titanium dioxide, 0～100 part in zinc oxide, 0～100 part in barium sulfate by weight.Three kinds of compositions can not be zero simultaneously.
Pigment of the present invention is a kind of mineral dye, aluminium powder, chromoxide green or chrome yellow or barba hispanica or cadmium red.
Promotor of the present invention is N, N xylidine, N, N-dimethyl-p-toluidine.
Softening agent of the present invention is dibutyl phthalate, dioctyl phthalate (DOP).
Anti-settling agent of the present invention is an aerosil.
Solvent of the present invention is solvesso100, solvesso150, ethyl acetate.
Solidifying agent of the present invention is a benzoyl peroxide.
Heat reflection coating for bituminous pavement of the present invention mixes A, B component by mass ratio 100: 0.1～5, stirs, and sprinkling or brushing are on the bituminous pavement top layer, and every square meter spreading amount is 0.5～1.5kg.
Heat reflection coating for bituminous pavement heat reflectivity of the present invention is strong, wear-resisting, anti-corrosion, weather-proof and snappiness is good.This material is used on the bituminous pavement top layer, can when summer high temperature, effectively reduce by 10～20 ℃ of pavement temperatures, reduce road surface thermostability disease, alleviating urban heat island effect.
