Description
Technical field
The invention belongs to elastomeric polymeric material fields, and in particular to it is a kind of coat inner barrel low calcium and magnesium glue lining and
Preparation method.
Background technique
The ability that there are rubber lining protection metal or other matrixes to corrode from multimedium, various rubber linings can not only
It is resistant to calculation, the corrosion of alkali, inorganic salts and other organic matters, and there is good comprehensive performance, such as elasticity, wearability, shock resistance
The cement properties of property, resistance to bend(ing), shock absorption and metal or other matrixes.In environment protection field, handle exhaust gas is column mostly
The cost of large-size cylinder body, these cylinders is high, and for a long time and exhaust gas contact, it will lead to the corrosion of cylinder inboard wall, therefore, use rubber
Lining liner prevents corrosion of the gas to cylinder inboard wall on cylinder inboard wall.Traditional rubber lining coats cylinder inboard wall
When, there are certain coincidence sides for bottle liner, although this coincidence side area is little, since inner barrel is by gas pressure
It influences, overlapping position can for a long time, which disengaged, even influences full wafer lining.Although some enterprises use periphery as concaveconvex structure
Lining, make to combine between the lining of adjacent laying more closely, but after lining receives waste-gas heat, it is swollen still to generate heat
It is swollen, cause adjacent lining junction to elapse, forms the problem identical with laying lining is overlapped.
Summary of the invention
Goal of the invention: in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide it is a kind of cladding inner barrel it is low
Calcium and magnesium glue lining.
Another object of the present invention is to provide the preparation methods of above-mentioned low calcium and magnesium glue lining.
Technical solution: in order to achieve the above object of the invention, what the present invention was specifically performed by: in a kind of cladding cylinder
The low calcium and magnesium glue lining in portion, including sheet colloid, the colloid periphery are concave-convex alternate structure, the protrusion on the colloid periphery
Structure is equipped with several through-holes.
Wherein, the concaveconvex structure is waveform, zigzag or circuit shape.
Wherein, described rubber lined with a thickness of 3 ~ 20mm.
Wherein, the diameter of the through-hole is not more than 1mm.
Wherein, the top diameter of the through-hole is different from base diameter, and forming through hole section is trapezoidal structure.
The low calcium and magnesium glue lining of above-mentioned cladding inner barrel, the component including following parts by weight: 40 ~ 50 parts of natural rubber
Glue, 20 ~ 22 parts of barium sulfate, 0.1 ~ 5 part of zinc oxide, 0.1 ~ 2 part of stearic acid, 0.1 ~ 2 part of diphenylguanidine and 0.5 ~ 5 part
Butter.
The method for preparing the low calcium and magnesium glue lining of above-mentioned cladding inner barrel, comprising the following steps: measure each original by formula
Material is kneaded, and is controlled 40 DEG C of temperature, is continued 3 ~ 5 minutes, and the mixture being kneaded importing mold is compressed into tablet form, is stood at room temperature
Natural cooling 11 hours or more.
Wherein, the length, width and height of the natural rubber are not more than 20cm.
Wherein, the mold is not less than 10kg to the pressure of mixture.
The utility model has the advantages that the present invention, compared with traditional technology, there are following advantages:
(1) present invention carries out interspersed combination by the concaveconvex structure of adjacent lining, while multiple through-holes being arranged on convex shape,
The expanded by heating that these through-holes reduce lining is possible, while when lining expanded by heating, through-hole takes the lead in being extruded and slowing down
Extruding to adjacent lining engaging portion；
(2) present invention uses special through-hole structure, and since exhaust gas flow is big in cylinder, pressure is high, therefore directly contacts exhaust gas
Through hole end diameter it is small, the through hole end diameter being bonded with cylinder is big, increase exhaust gas invade cylinder pressure, ensure that cylinder
Service life.
