Abstract
The invention discloses a kind of foaming modification bituminous compositions, which is characterized in that composed of the following components：Asphalt：80 100 parts, PE expanded beads：20 30 parts, PE asphalt modifiers：5 10 parts, plasticiser：0.1 0.5 parts, surfactant：0.1 0.3 parts, coupling agent：0.01 2 parts.After this technical solution, it is introduced directly by PE expanded particles for the gas needed for foamed asphalt, without using special water filling, air injection equipment to foam pitch, and pitch can be synchronized in process and carry out PE modifications, to reduce manufacturing procedure, equipment investment is reduced, and production efficiency is high, process regulation is simple.
Description
Technical field
The present invention relates to modified pitch fields, more particularly, to a kind of foaming modification bituminous composition.
Background technology
Asphalt foaming is a kind of common bitumen treatment process, and cardinal principle is that cold water is added in hard pitch, heat
Heat exchange can occur with water drops surface for pitch, and water droplet heating is evaporated, and generate steam, it is tiny that these steam so that pitch generates
Bubble, to expand.Asphalt viscosity under this state significantly reduces, can be easily uniform with cold wet grain mix.
Chinese invention patent CN104452530A once disclosed a kind of asphalt foaming technology, in asphalt foaming process
In, more fine gas bubbles are provided for pitch using high pressure gas, have reached more better than using only cold water evaporation foaming mode
Foaming effect.This foaming technique needs special cold water, gas to introduce equipment, and the production time is long, required processing temperature
It is high.
Chinese invention patent CN104448865A also once disclosed a kind of foaming modification bituminous composition and preparation method thereof,
Utilize the emulsifier of asphalt modifier, 1-8wt%, the foam stabiliser of 1-2wt%, 0.01- added with 35-65wt%
Modifying agent and the water generated needed for steam are introduced system by the water-based emulsion of 3wt% coupling agents and 23-63wt% water in advance, with
Just modified and foamed process is merged, achievees the purpose that save the production time.But such technology is still without departing from using cold water to generate
Gas is to realize the technical thinking of asphalt foaming, and technique is difficult to control.
Invention content
The purpose of the present invention provides a kind of previously-introduced gas aiming at the deficiencies in the prior art, nothing in process
It needs special cold water, gas to introduce equipment, and the foaming modification bituminous composition for realizing that PE is modified can be synchronized.
In order to achieve the above object,
The technical solution adopted by the present invention is：
A kind of foaming modification bituminous composition, is grouped as by the group of following parts by weight：
Asphalt：80-100 parts, PE expanded beads：20-30 parts, PE asphalt modifiers：5-10 parts, plasticiser：0.1-
0.5 part, surfactant：0.1-0.3 parts, coupling agent：0.01-2 parts.
Preferably, a kind of foaming modification bituminous composition, is grouped as by the group of following parts by weight：
Asphalt：90 parts of PE expanded beads：28 parts, PE asphalt modifiers：8 parts, plasticiser：0.3 part, surface-active
Agent：0.2 part, coupling agent：1 part.
Preferably, the coefficient of foaming of the PE expanded beads is 45.
Preferably, the PE asphalt modifiers mesh number is 250 mesh.
Preferably, the PE expanded beads are foamed by PE reworked materials.
In above technical scheme, due to having a large amount of bubbles in the PE expanded beads, therefore put into pitch
Afterwards, under 150 degrees Celsius of even lower processing temperatures, bubble in the PE expanded beads or escape to composition system
In, or be still in the PE expanded beads, provide the gas generated needed for bubble for composition system；In addition, by institute
It is larger to state PE expanded beads grain sizes, is easily layered in composition system, therefore the PE asphalt modifiers that need to add small particle are used
In stability of the promotion PE expanded beads in composition system, and the PE modified effects of pitch can be substantially improved simultaneously；
Again, the homogeneity of composition system can be further increased by plasticiser, surfactant, coupling agent being added in composition system
And stability.
The beneficial effects of the invention are as follows：The present invention is to provide a kind of foaming modification bituminous compositions, utilize PE foaming
Grain introduces the required gas of foaming, while PE asphalt modifiers being coordinated to keep PE expanded beads more stable in system, is more easy to make drip
Blueness is modified, and after such technical solution, that brings has the beneficial effect that：
1, using PE expanded beads introduce foaming needed for gas, without using special water filling, air injection equipment to pitch into
Row foaming, and it is not necessarily to foamed process, and production efficiency is high, process regulation is simple.
2, PE asphalt modifiers are added in the composition, composition is made to be not easy to be layered, it is more stable, and the modified of pitch is imitated
Fruit is good.
3, it using reworked material PE expanded beads, can realize waste utilization, realize that past heritage utilize and energy conservation and environmental protection purpose.
