Description
Technical field
The present invention relates to a kind of bituminous material and preparation method thereof, particularly relate to resistance to bituminous material frozen of a kind of stretch-proof and preparation method thereof.
Background technology
In some severe cold areas, bituminous material is used on road surface as a part for ground surface material, and owing to being in cold state for a long time, the resistance to index of freezing of bituminous material is poor, can frequently produce the situation such as crack, caking.The generation of these rough sledding, can affect the application of bituminous material.In addition in the use procedure of bituminous material, the stretch resistance of bituminous material also has larger effect to bituminous material, stretch-proof performance and frost resistance all can have larger impact to bituminous material, improve stretch-proof performance and the frost resistance energy of bituminous material, the problems referred to above produced after severe cold area uses for a long time can be solved.
Summary of the invention
The technical problem solved: stretch-proof poor-performing, the frost resistance of conventional bituminous material can be poor, produce the problems such as crack after the life-time service of severe cold area.
Technical scheme: the invention discloses resistance to bituminous material frozen of a kind of stretch-proof and preparation method thereof, the resistance to bituminous material frozen of stretch-proof is made up of according to weight ratio following composition: petroleum pitch is 27 ~ 36 parts, mineral oil is 4 ~ 9 parts, polyoxyethylene stearic acid ester is 13 ~ 17 parts, polyisoprene is 12 ~ 14 parts, Hydroxyethyl acrylate is 7 ~ 12 parts, the acid of 4-vinylbenzene is 7 ~ 8 parts, butanols is 19 ~ 24 parts.
The preparation method of the resistance to bituminous material frozen of a kind of stretch-proof, comprise the following steps: (1) gets that petroleum pitch is 27 ~ 36 parts, mineral oil is 4 ~ 9 parts, polyoxyethylene stearic acid ester is 13 ~ 17 parts, petroleum pitch, mineral oil, polyoxyethylene stearic acid ester are mixed, after mixing, mixture temperature is promoted to 95 DEG C, again carries out being mixed to evenly; (2) in mixture, add that polyisoprene is 12 ~ 14 parts, Hydroxyethyl acrylate is 7 ~ 12 parts, butanols is 19 ~ 24 parts successively, mix after adding each composition; (3) mixture temperature is increased to 125 DEG C; (4) adding the acid of 4-vinylbenzene is 7 ~ 8 parts, stirs 1 ~ 2h, fully reacts, prepare the bituminous material that stretch-proof is freeze proof.
Wherein, the petroleum pitch added in the preparation process of bituminous material is preferably 36 parts.
Wherein, the Hydroxyethyl acrylate added in the preparation process of bituminous material is preferably 7 parts.
Wherein, the 4-vinylbenzene acid added in the preparation process of bituminous material is preferably 8 parts.
Beneficial effect: the bituminous material prepared by the inventive method has good frost resistance energy and stretch-proof performance, places after 100 days to 150 days, after bituminous material returns to room temperature, do not produce deformation and change of properties at temperature is-30 DEG C.Determine the stretch-proof performance of bituminous material, the tensile strength of bituminous material of the present invention is 15.8MPa to 16.4MPa, has good tensile property.
