Summary of the invention:
Technical problem to be solved by this invention is to provide the plastics extruder barrel clean-out system that a kind of cleaning performance is good, the used time is short.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of plastics extruder barrel clean-out system, be made up of the raw material of following mass fraction:
Calcined diatomite 100-110 part, nano titanium oxide 15-20 part, tea seed powder 40-45 part, coconut powder 20-25 part, polyoxyl 40 stearate 15-20 part, rosin 15-20 part, polyoxyethylene octylphenol ether 12-15 part, antirust additive 12-15 part, soda powder 10-15 part, lacquer thinner 10-15 part, polyacrylamide 8-12 part, epoxy propane butyl ether 8-12 part, S-WAT 6-10 part, olein 4-8 part, diesel oil 80-100 part, ethanol 150-200 part;
Its preparation method is as follows:
(1) be first scattered in ethanol by calcined diatomite and nano titanium oxide, then supersound process 25-30min at ultrasonic frequency 22kHz, temperature 45-50 DEG C, obtains modification infusorial earth solution;
(2) tea seed powder, coconut powder and soda powder are added in diesel oil, mix rear standing 15-20min, then add polyoxyethylene octylphenol ether, polyacrylamide, S-WAT and olein, be heated to 55-60 DEG C of insulated and stirred 15-20min, obtain material I;
(3) in modification infusorial earth solution, add polyoxyl 40 stearate, rosin, lacquer thinner and epoxy propane butyl ether, after mixing, namely obtain material II;
(4) material I, material II and antirust additive are added in ball mill, be milled to fineness and be less than 0.1mm.
Described antirust additive is mixed by the raw material of following parts by weight: soap powder 15-18 part, oil meal 12-15 part, turps 12-15 part, Vaseline 8-12 part, epoxy soybean oil 8-12 part, sulfonated castor oil 6-10 part, zinc naphthenate 6-10 part, styracin 5-8 part, Sodium Benzoate 4-7 part, Sodium Nitrite 2-5 part.While barrel is cleaned, antirust treatment is carried out to it, thus extend the work-ing life of barrel and prevent the quality affecting extruded product because getting rusty.
Described tea seed powder needs to carry out pre-treatment before using, concrete treatment step is: be first added to the water by 25-30 part tea seed powder and soak 5-8h, filter, wash, then add 2-3 part aerosil and 3-5 part organic clay, through drying, being ground into powder after grinding 25-30min.Tea seed powder, by pre-treatment, can not only improve soil removability, also can extend the shelf life.
The invention has the beneficial effects as follows: the present invention take calcined diatomite as main raw material, utilize nano titanium oxide to its modification, and be aided with the auxiliary agents such as tea seed powder, coconut powder, not only cleaning performance is good for obtained clean-out system, used time is short, and itself easy-clear, use rear ethanol barrel can remove clean-out system residual on barrel.
