Abstract
The invention relates to the technical field of waterproof materials, and particularly relates to a regenerated rubber powder modified asphalt self-adhesion waterproof coiled material. The regenerated rubber powder modified asphalt self-adhesion waterproof coiled material comprises asphalt rubber modified asphalt, SBS (Styrene Butadiene Styrene), a plasticizing agent and filler. The regenerated rubber powder modified asphalt self-adhesion waterproof coiled material is characterized in that the asphalt is road petroleum asphalt at a 70# grade; a formula comprises the following materials in percentage by weight: 40%-55% of asphalt, 10%-15% of aromatic oil, 3%-5% of SBS, 10%-15% of regenerated rubber powder, 1%-3% of auxiliary agents and 10%-20% of filler; the formula is different from a common rubber powder modified asphalt coiled material, the self-adhesion coiled material prepared according to the formula has very good low-temperature flexibility and greatly enhances the stripping strength with cement mortar. Thus, the self-adhesion coiled material disclosed by the invention is more excellent in property and greatly enhanced in construction application.
Description
Technical field
The present invention relates to water-proof material technical field, specifically a kind of ground rubber Modified asphalt self-adhesion waterproof rolling material.
Background technology
In recent years, along with the development of chemical building material, architectural waterproof material kind is more and more, and corresponding material modified industry increases year by year, and along with China's rapid development of economy, auto output also rolls up year by year, faces in recent years a large amount of junked tire processing.The bulk deposition of junked tire will bring huge social concern, as worsened environment, destroy plant-growth, jeopardizing ball ecological environment.Junked tire is processed into the treatment process that waste rubber tyre powder is generally acknowledge in the world innoxious, resource utilization, is wherein one of main path by waste and old tire rubber powder as highway industry medium pitch properties-correcting agent.And how to process junked tire, and bring into play best modified effect, make the treatment process of its junked tire and method become the new direction of a lot of companies and producer's research.Enterprise utilizes the formula of the rubber powder modified asphalt that How to choose processed also to become the most important thing of research.
Present stage, the waste rubber powder wide material sources of selecting when a large amount of waterproofing enterprises utilizes rubber powder modified asphalt, colloid composition is extremely unstable, a large amount of plastic grains and powder have adulterated in waste rubber powder, this type of rubber powder is difficult to the effect of performance rubber powder modified asphalt in modifying asphalt formula, the modifying asphalt formula physics mechanical performance index of making is poor, and the shelf lives is bad.Waste rubber powder more just serves as the effect of stopping composition.
So water-proof material manufacturing enterprise is in selecting rubber powder, a kind of colloid stable components of How to choose, steady sources, gel content rubber powder high, process desulfurization processing become the key of selecting waste rubber powder.
This technology is exactly the requirement that combines present situation and the asphalt modification technology in current rubber powder market, has selected a kind of colloid stable components and has carried out modifying asphalt through the rubber powder of desulfurization processing.Make it in the time of modifying asphalt, substitute a large amount of SBS.Useless affect quality product in, not only reduced product cost, also well realized resource recycling, protected environment.
Summary of the invention
The object of this invention is to provide a kind of adhesive waterproof coil of the asphalt modification in self-adhesive coiled material technology, improve the bond effect of self-adhesive coiled material and the low temperature flexibility of coiled material by a kind of selection of rubber powder, have very high practical value.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ground rubber Modified asphalt self-adhesion waterproof rolling material; comprise asphalt rubber modifying asphalt, SBS, softening agent and stopping composition; it is characterized in that: described pitch is bi tumenf orr oad 70# grade, formula consists of pitch 40～55%; Aromatic hydrocarbon oil 10～15%; SBS3%～5%; A kind of ground rubber 10～15%; Auxiliary agent 1～3%; Stopping composition 10～20%.
The invention has the beneficial effects as follows:
1, this formula is different from common rubber powder modified asphalt coiled material, and the self-adhesive coiled material low temperature flexibility of making is splendid, improves very large with the stripping strength of sand-cement slurry.Make the performance of self-adhesive coiled material more excellent, applicability in construction has also obtained large increase.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should understand, these embodiment are only not used in and limit the scope of the invention for the present invention is described, in addition should understand, after having read the content of the present invention's instruction, those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values drop on application appended claims limited range equally.
A kind of ground rubber Modified asphalt self-adhesion waterproof rolling material, comprises asphalt rubber modifying asphalt, SBS, softening agent and stopping composition, it is characterized in that: described pitch is bi tumenf orr oad 70# grade, and formula consists of pitch 40～55%; Aromatic hydrocarbon oil 10～15%; SBS3%～5%; A kind of ground rubber 10～15%; Auxiliary agent 1～3%; Stopping composition 10～20%.
Rubber powder is waste old through the pulverizer cross-linked structure that ruptures, and its surface of a large amount of molecular fragment particles of generation is ellipse property, is a kind of forming containing crosslinking structure material of being made up of multiple materials such as rubber, carbon black, tenderizer and vulcanization accelerators.It mixes because surface properties is different from pitch, makes the intermiscibility between them poor, and rubber powder is directly mixed in pitch and is difficult to form good bonding interface, easily produces segregation or deposited phenomenon.Therefore by certain method, vulcanized rubber powder is carried out to modification, impel rubber powder to be combined with the interface of the macromolecular materials such as pitch.
This rubber powder through desulfurization processing, adds a kind of linking agent in the time producing in sweetening process, and the surfactivity of rubber powder is improved.The effect that this rubber powder active substance in the time of modifying asphalt serves as " bridge " connects rubber powder and pitch medium.
