Abstract
A kind of good plastic cement flange formula of heat resistance, it is characterised in that：Raw material is become with the group of weight percent：Without silicon polypropylene 6 15%, 1# oil 10 18%, microcrystalline wax 38 45%, C9 Petropols 6 15%, naphthenic oil 10 18%.The present invention can make a kind of good plastic cement flange of heat resistance, its high temperature resistance reaches 85 DEG C, and after high-temperature behavior is tested, plastic cement flange is non-fusible, indeformable by the change of material rate in being formulated to plastic cement flange；Resistance to low temperature reaches 40 DEG C, not fragmentation, indeformable, warping strength after cryogenic property is tested.
Description
Technical field
The present invention relates to a kind of plastic cement flanges, particularly relate to a kind of good plastic cement flange formula of heat resistance.
Background technology
Plastic cement flange is mainly used for sanitary ware industry, the connection of lower-discharging type toilet seat sewage draining exit and blow-off pipe, due to toilet seat
It is typically mounted on bathroom, has high temperature resistant requirement；In addition it may also use, have low temperature resistant under the severe cold condition of northern area
It is required that.
Plastic cement flange high-temperature resistant performance is typically 60 DEG C at present, resistance to low temperature usually -20 DEG C, but in actual life due to
Sometimes temperature is more than 60 DEG C to certain reason, and even higher, at this moment common plastic cement flange just cannot be satisfied the requirement of product characteristic；
Such as under the severe cold condition of northern area in use, such as the Inner Mongol, Heilungkiang area, at this time resistance to -20 DEG C of plastic cement flange also without
Method meets the requirement of product characteristic.Therefore, that there are use environments is limited for current plastics flange, causes the problem that the service life is bad.
Invention content
The object of the present invention is to provide a kind of good plastic cement flange formulas of heat resistance, to effectively improve plastic cement flange
Use environment and service life.
To achieve the above object, solution of the invention is：
A kind of good plastic cement flange formula of heat resistance, it is characterised in that：Raw material is become with the group of weight percent：Nothing
Silicon polypropylene 6-15%, 1# oil 10-18%, microcrystalline wax 38-45%, C9 Petropols 6-15%, naphthenic oil 10-18%.
After adopting the above scheme, the present invention can make one kind by the change of material rate in being formulated to plastic cement flange
The good plastic cement flange of heat resistance, its high temperature resistance reaches 85 DEG C, and after high-temperature behavior is tested, plastic cement flange does not melt
Change, is indeformable；Resistance to low temperature reaches -40 DEG C, not fragmentation, indeformable, warping strength after cryogenic property is tested.
Specific implementation mode
Present invention is disclosed a kind of good plastic cement flange formula of heat resistance, raw material composition is according to weight percent：
Without silicon polypropylene 6-15%, 1# oil 10-18%, high-melting-point microcrystalline wax 38-45%, C9 Petropols 6-15%, naphthenic oil 10-18%；
The no silicon polypropylene is mixed mostly mainly as the framework material under high temperature, ratio 6-15% without silicon polypropylene
It does not glue then, poor sealing！
The 1# oil is as high viscosity heavy oil, kinematic viscosity（100℃）≥50mm2/ s, density（20℃）>=0.94, it can
The filling bridging action of the surface viscosity of product is improved, ratio 10-18% has mixed mostly the softening point temperature that can then reduce product,
It mixes and has lacked and viscosity can be influenced.
High-melting-point microcrystalline wax fusing point >=80 DEG C（Usual paraffin melting point≤65 DEG C, it is high-melting-point that paraffin, which is more than 65 DEG C,
Microcrystalline wax）, high-melting-point microcrystalline wax is the main carriers for meeting properties of product, and ratio 38-45% is the resistance to of plastic cement flange
The key point of high temperature.
The Petropols are one of refinery products, have the corresponding product grade of several different melting points such as C4, C5,
C6 ... C9 etc., we select C9 Petropols, fusing point >=145 DEG C that can adjust the softening point of product, but mix than being key,
Although having mixed more, product heat-resisting quantity improves, and surface is not glued, and resistance to low temperature reduces again, mixes that have lacked heat-resisting quantity poor
And product does not glue.Through repetition test, it is 6-15% to be suitble to mix than ratio.
The additive that the naphthenic oil is not cracked as raising product surface viscosity and surface, ratio 10-18% is comprehensive
Close the conditioning agent of physical property.
After carrying out raw material proportioning according to above-mentioned weight percent, raw material is reacted into the air-cooled demoulding-packet of melting-cast molding-
Dress just completes the making of plastic cement flange.
Raw material reacts melting：Load weighted raw material is sequentially placed into and has set temperature（220℃）Reaction pot in, open
Blender carries out melting, and the reaction time continues 4 hours.
Cast molding：The liquid material that the reaction was complete is put into storage vat after cooling half an hour and is slowly pumped into blanking barrel,
It is molded into aluminum die cavity by counting material blanking device automatically again.
Air-cooled demoulding：It opens automatic cooling assembly line and support industry fan is cooled down, after product cooling, by plastic cement
Flange takes out from aluminum die cavity.
In conclusion the present invention can make a kind of temperature tolerance by the change of material rate in being formulated to plastic cement flange
The good plastic cement flange of energy, its high temperature resistance reaches 85 DEG C, and after high-temperature behavior is tested, plastic cement flange is non-fusible, constant
Shape；Resistance to low temperature reaches -40 DEG C, not fragmentation, indeformable, warping strength after cryogenic property is tested.
