Abstract
An internal barrel of water heater is prepared from thermoplastic polypropene resin, inorganic fillter (600-1200 meshes grain size) and coupling agent for surface treatment and modifier through high-speed uniformly mixing, extruding out, granulating, and injection moulding under certain temp. and pressure. Its advantages are high productivity, performance and quality, and environmental protection.
Description
The present invention relates to a kind of manufacture method of plastics, the manufacture method of bucket in particularly a kind of water-heater plastics.
At present, internal cylinder of water heater generally is to make of enamel, complex process comprises tens procedures, even to the strict control of each production workshop section, can not avoid the defective of appearance in the enamel production fully: bucket is by steel plate external enamel coating glaze in the enamel, weight is bigger, because the enamelware unrelieved stress is excessive, easily takes off porcelain again, thereby cause and take off the porcelain place and get rusty, influence water quality; In addition, the enamel plant produced also is one of comparatively serious source of pollution of polluted water, is unfavorable for the protection of ecotope; Enamel plant and original equipment manufacturer equipment is huge, complicated, as all setting up the three wastes in large scale and handle the workshop, then drop into highly in that enamel plant, enamel factory being other, and fund is difficult to reclaim in a short time.
Purpose of the present invention is exactly in order to overcome that there is defective in above-mentioned prior art and manufacture method that a kind of internal cylinder of water heater is provided, and this method can be enhanced productivity, and improves product properties, improves the quality of products, and helps environment protection.
Purpose of the present invention can realize in the following manner:
A kind of manufacture method of internal cylinder of water heater is characterized in that, it adopts the modified thermoplastic resin composition to make described modified thermoplastic resin composite formula following (weight percentage):
Polypropylene (PP) 50～60%
Polypropylene grafted MALEIC ANHYDRIDE (PP-g-MAH) 5～15%
Mineral filler 25～35% through coupling agent treatment
Primary antioxidant 0.05～0.3%
Auxiliary anti-oxidant 0.25～0.6%
Processing and lubrication auxiliary agent 0.05～0.3%
Above-mentioned composition is mixed in homogenizer, by twin screw extruder 200 ℃～230 ℃ following blend granulations, make thermoplasticity modified polypropylene plastic particle, descend drying after 3～5 hours at 90 ℃～120 ℃ on this modified plastics particle then, by injection moulding machine under the pressure condition of 210 ℃～230 ℃ temperature and 60～100MPa (MPa), inject designed internal cylinder of water heater injection mold, 1～2 minute to be cooled, can obtain the internal cylinder of water heater of moulding.
Described mineral filler through coupling agent treatment can be the mica powder of handling through γ-An Bingjisanyiyangjiguiwan, and its particle diameter is 600～1200 orders.
Described primary antioxidant is a Hinered phenols, can be antioxygen 1010, i.e. four [β-(3,5-di-tert-butyl-4-hydroxy phenyl) propionic acid] pentaerythritol ester.
Described auxiliary anti-oxidant is a sulfocompound, can be DLTP, i.e. Tyox B.
Described processing and lubrication auxiliary agent can be a calcium stearate.
Also can add glass fibre alkali-free rove in the described modified thermoplastic resin composite formula as strongthener.
Compared with prior art, the prepared internal cylinder of water heater of the inventive method has more advantage and effect, it not only can improve the production efficiency of goods, reduces product weight, and can guarantee required intensity, rigidity, the life-time service temperature of goods can reach more than 100 ℃, its heat-insulating property also improves greatly, and dimensional stability improves, and helps environmental protection, because the simplification of operation, production cost and input reduction greatly in advance.
Below by specific embodiment, the invention will be further described.
