Abstract
The present invention discloses an asphalt filler compound for improving the asphalt performance, and belongs to the technical field of chemical engineering. The asphalt filler compound is characterized in that the asphalt filler compound is prepared from 5 to 18% of sepiolite, 20 to 40% of grammite, 20 to 40% of talc and 25 to 50% of barite which are respectively processed into different specification fineness and are uniformly mixed according to weight percentage. When the asphalt filler compound is added into the asphalt, the asphalt filler compound has the advantages of enhancement of cohesiveness, abrasive resistance performance and plasticity of asphalt, low-temperature crack resistance performance, sun solarization resistance performance, decrease of asphalt dosage and cost reduction.
Description
Technical field
The present invention relates to a kind of pitch filler, specifically a kind of mineral composition filler that improves asphalt performance belongs to chemical technology field.
Background technology
The bituminous performance is excellent, and purposes is wide, has water insolublely, glossy, and cohesiveness, water resisting property, antiseptic property are good, and generally about 1.15-1.25, low temperature is fragility to density, is mainly used in industry such as coating, plastics, rubber and surfacing etc.Surfacing be bituminous concrete, promptly do gelling material with pitch, sand, stone are done aggregate, the concrete that forms is mixed and stirred in heating.Because pitch cohesiveness is not really strong, low temperature is fragility, and the road surface resistance to compression shake-proof ability that is paved into is low, and no matter in the tropical climate district or as the same the existing in road surface of cold band climatic region, the easy bleed in road surface in summer is heated deliquescing and causes the road surface bubbling phenomenon of curling under weight; Fracture and crack performance also appear winter.During people's making bituminous pavement, pitch and stone are difficult to make pitch and stone to form closely knit integral body when mixing parcel, though through weight repeatedly, because pitch and stone proportion differ bigger, tend to form tiny cavity and pore, influence the whole density and the resistance to compression homogeneity of bituminous pavement therefrom.Denomination of invention is: a kind of paligorskite composition modified asphalt and preparation method thereof, application number is: 200510092866.0 Chinese patent application discloses a kind of paligorskite composition modified asphalt, it is to be 90～95 parts of matrix pitches by weight ratio, 1～3 part of polygorskite, 2～5 parts styrene-butadiene rubber(SBR), 1～4 part of viscosity increaser is formed.Though this paligorskite composition modified asphalt can improve the shortcoming that above-mentioned pitch exists preferably, also exist asphalt content big, add organism and cause the high weak point of cost.
Summary of the invention
Task of the present invention provides a kind of mineral composition filler that improves asphalt performance, can improve pitch cohesiveness, wear resistance, plasticity-, the performance that anti-cold(ing)crack, anti-sun light are exposed to the sun, and reduce asphalt content, reduce cost.
For realizing task of the present invention, technical solution of the present invention is as follows:
A kind of pitch filler composition of the present invention, it is made up of following weight degree component:
Sepiolite 5-18% wollastonite 20-40% talcum 20-40% barite 25-50%.
The making method of a kind of pitch filler composition of the present invention is processed as the 200-325 order respectively with sepiolite, barite, and talcum is processed as the 600-800 order, and wollastonite is processed as the 800-1250 order, mixes and gets final product by weight getting above-mentioned raw materials respectively.
Sepiolite is white in color, yellow or gray bulk or fibrous, absorbs the very capable of liquids and gases, and frame is good altogether, and industrial having many uses can be done siccative, absorption agent, decolourizing agent etc.Be widely used at present rubber tyre, senior in exterior wall latex paint medium.Be used in the pitch, can improve the bituminous weathering resistance and strengthen bituminous fracture resistence force and tear strength, increase bituminous agglomerating force and degree of cure, strengthen the bituminous bounding force, and can reduce the bituminous heat transfer rate, make pitch have relative thermostability.
Talcum, monoclinic crystal, normal slabbing, flakey or compact mass aggregate, pale green or white.Vitreous luster; Proportion 2.7-2.8; Soapy feeling is arranged; Be widely used in industry such as papermaking and rubber.Be used in the pitch, can improve the bituminous flowability, promote pitch and stone evenly to ooze and close, also can strengthen the relatively hot stability of bituminous pavement.
Wollastonite, triclinic(crystalline)system, normal slabbing crystal is generally radial or fibrous agrregate.White, little band light gray or light red.Vitreous luster; Proportion 2.78-2.91; At industrial wide application.Be applied in the bituminous pavement road, can increase the bituminous volume weight, can improve the bituminous weathering resistance, strengthen the relatively hot stability of bituminous pavement.
Barite, rhombic system often becomes platelike crystal or granular aggregate.Water white transparency, impure person often shows ash, red isochrome.Vitreous luster; Proportion 4.3-4.5; Stable chemical performance is widely used in industry such as oil, chemical industry, rubber, pottery, glass, wireless and the roentgen-ray laboratory.Be applied in the bituminous pavement road, the one, can increase the bituminous volume weight, pitch and stone proportion are narrowed the gap; The 2nd, can intercept the ultraviolet ray in the daylight and weaken pitch heat passage when be exposed to the sun by the sun, thereby improve the thermal distortion that is subjected to of bituminous pavement greatly, make bituminous pavement pine for the stability that keeps relative in chilling speed.
The present invention utilizes the characteristic of above-mentioned substance, as the bituminous filler, has the pitch of raising cohesiveness, wear resistance, plasticity-, the performance that anti-cold(ing)crack, anti-sun light are exposed to the sun, and reduce asphalt content, the advantage that reduces cost.
The using method of a kind of pitch filler composition of the present invention:
Among mineral composition adding hydrothermal solution pitch of the present invention, stir and can use, application quantity is 20 of an asphalt content---35%, when repairing road, consumption can be brought up to 40%.
Embodiment
Respectively sepiolite is processed as 200 orders, barite is processed as 325 orders, and talcum is processed as 800 orders, and wollastonite is processed as 1250 orders, mixes and gets final product by weight getting above-mentioned raw materials respectively.
Produce 1000 kilograms of each components of the present invention and consumption (kilogram) thereof.
Example 1 sepiolite 5 wollastonites 20 talcums 25 barites 50.
Example 2 sepiolites 18 wollastonites 37 talcums 20 barites 25.
Example 3 sepiolites 10 wollastonites 25 talcums 40 barites 25.
Example 4 sepiolites 5 wollastonites 40 talcums 20 barites 35.
