Abstract
A production method for an antibacterial dripper for drip irrigation comprises the following steps: (1) performing cleaning, sorting, crushing and dewatering on waste and old high-density polyethylene plastic, and then granulating, so as to prepare a high-density polyethylene reworked material; and (2) baking the high-density polyethylene reworked material obtained in the step (1) at 80 DEG C-90 DEG C for 4 h, and then uniformly mixing with high-density polyethylene, linear low-density polyethylene, antibacterial master batch and color batch, and performing heating plasticization, mold closing, injection, pressure keeping and cooling fixing, so as to obtain a finished product. The waste and old high-density polyethylene plastic is taken as the main raw material, so that the product cost is greatly reduced, and energy is saved and environment is protected. The antibacterial master batch gives play to effects of killing and inhibiting mould and preventing ageing, and has good dispersion effect when being added in the form of mater batch. The produced antibacterial dripper has obvious obstruction-resistant performance, mould killing and inhibiting performances, ageing resistant performance and other excellent performances.
Description
Technical field
The invention belongs to drip irrigation product technical field, particularly relate to the production method of a kind of drip irrigation with antibacterial water dropper.

Summary of the invention
The present invention provides a kind of low cost of manufacture, economic environmental protection, anti-clogging, kills the production method pressing down the antibacterial water dropper of the age inhibiting drip irrigation of mould for solving in known technology the technical problem that exists.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of drip irrigation production method of antibacterial water dropper, comprises the following steps:
(1) waste and old high-density polyethylene plastics carried out clean, sort, carry out granulation after broken, dehydration, be prepared into high density polyethylene(HDPE) reworked material;
(2) after mixing with high density polyethylene(HDPE), LLDPE, antiseptic-germicide master batch, look mother after the high density polyethylene(HDPE) reworked material of step (1) gained being dried 4 hours at 80 DEG C-90 DEG C, after heat plasticizing, mold closing, injection, pressurize, cooling and shaping, get product; Its medium high density polyethylene reworked material, high density polyethylene(HDPE), LLDPE, antiseptic-germicide master batch, look mother stock be not by 40-60,10-30,10-20,1-10,0.5-1 of massfraction.
The present invention can also adopt following technical scheme:
The production method of described antiseptic-germicide master batch comprises the following steps:
A inorganic complex antimicrobials and tensio-active agent join in high-speed mixer simultaneously carry out high-speed mixing stirring 20-30min by (), be then warming up to 80 DEG C-90 DEG C gradually and dry 2-3 hour, discharging is sieved and obtained surface-treated inorganic complex antimicrobials;
B the inorganic complex antimicrobials obtained in step (a) and dispersion agent, vector resin are sequentially added in high-speed mixer and stir 20-30min and mix by (), afterwards the above-mentioned material mixed is obtained described antiseptic-germicide master batch through the granulation of double-screw extruding pelletizing machine.
The composition weight ratio of described inorganic complex antimicrobials, tensio-active agent, dispersion agent, vector resin is 30%-40,0.5%-4%, 2%-7%, 40%-60% meter.
Described inorganic complex antimicrobials is take zeolite as the metallicity antiseptic-germicide of carrier, and antimicrobial component is silver and zinc, and median size is less than 1 μm.
Prilling temperature condition in described step (1) is 180 DEG C-250 DEG C.
In described step (b), double-screw extruding pelletizing machine prilling temperature is 170-230 DEG C.
The advantage that the present invention has and positively effect are:
1, the present invention adopts waste and old high-density polyethylene plastics as main raw material, greatly reduces production cost, serves the effect of energy-conserving and environment-protective, significant to the raising competitiveness of product in market.
2, in the present invention, antiseptic-germicide master batch not only kills and presses down the age inhibiting effect of mould, and adds with the form of master batch and have good dispersion effect.
3, can find after detecting finished product of the present invention, finished product of the present invention has obvious anti-clogging, kills premium propertiess (see table one) such as pressing down mould anti-aging.
