Description
Technical field
The present invention relates to chemical material technical field, a kind of high-performance joint closure glue and its preparation are concretely related to
Method.
Background technique
Also therefore with the continuous improvement of people's living standards, automobile is ridden instead of walk and is also increasingly gradually grown, and the damage that road surface is subjected to
Increase, road maintenance department wants the crack of frequent road pavement and pit slot timely to be repaired.But gap-filling glue used at present
It there is a problem that following: (1) being formulated relatively complicated；(2) high-temperature stability and ageing resistance are poor, winter temperature compared with
It is easier to become fragile and crack in the case where low, is not suitable with cold temperature difference area, bad with bituminous pavement cementability, summer can go out
It is now outer to move；(3) when temperature could use after subzero environment is needed and heated to gap-filling glue, this just gives road maintenance department tieing up
It repairs and causes trouble in use process, waste of manpower and material resources；(4) high production cost；(5) environmental pollution is serious.
Summary of the invention
The purpose of the invention is to provide a kind of formulas rationally, low production cost, a kind of high-performance easy for construction
Joint closure glue and preparation method thereof.
The present invention provides a kind of high-performance joint closure glue, and based on parts by weight, raw material includes: modified pitch 80-
110 parts, 30-50 parts of chlorobutadiene, 10-30 parts of Petropols, 10-30 parts of rubber powder, 5-8 parts of pitch softening agent, styrene-fourth
6-12 parts of styrene block copolymer, 10-20 parts of asphalt stabilizer and 10-15 parts of long glass fibres, antioxidant 2-5
Part.
A kind of preparation method of high-performance joint closure glue, comprising the following steps: a, modified pitch is heated to 160~
200℃；B, in the case of stirring, by chlorobutadiene, pitch softening agent, Styrene-Butadiene-Styrene Block Copolymer point
It is not added in the modified pitch of above-mentioned melting state；C, after being completely dissolved, Petropols, rubber powder, asphalt stabilizer are added, it is long
Glass fibre stirs evenly.
Preferably, the asphalt stabilizer is sulphur, phosphorus, mixture two or more in lime stone
Preferably, the long glass fibres length is 20-40mm.
Preferably, the rubber powder be one of butyl rubber, ethylene propylene diene rubber, nitrile rubber, butadiene rubber or
It is several.
Preferably, the antioxidant is Hinered phenols antioxidant.
In conclusion beneficial effects of the present invention:
This product has high-temperature stable, and ageing resistance is good, and anti-low-temperature cracking is excellent, and elastic effect is good, summer not outer shifting, winter
Non-brittle, the temperature difference that seasons oneself to cold is regional, and long service life is good with bituminous pavement cementability.Component Source is wide, and production cost is not
Height does not pollute environment.
