Abstract
The present invention relates to a kind of preparation method of plastics deicer.The plastics deicer main component is anhydrous calcium oxide micro mist, three（Dioctyl pyrophosphoryl epoxide）Isopropyl titanate, ethylene-vinyl acetate copolymer, low molecular weight polyethylene.The preparation method of the plastics deicer is first to crush anhydrous calcium oxide, is prepared into anhydrous calcium oxide micro mist, then is mixed by weight percentage with other constituents, is made through bispin screw pelletizer extruding pelletization.Use, without heating, drying, do not consume energy, water removal effect is splendid after the plastics deicer is directly mixed by 1 3% weight with water containing plastic during use.
Description
Technical field
The invention belongs to technical field of plastic, is related to a kind of preparation method of plastics deicer.
Background technology
All plastics all contain a certain amount of moisture, need to remove the moisture in plastics, ability in plastics secondary operation
Processing（Extrusion, injection, blowing, calendering）Go out the plastic products of qualification.
Common plastics water-eliminating method, is that plastics are added heat drier, the moisture in plastics is allowed by thermal evaporation, so as to remove
The moisture in plastics is removed, or is removed the moisture in plastics with the method for heated-air drying.The physics water removal of this heat drying
Method, must there is special drying equipment, drying time length（Generally want 2-6 hours）, energy consumption is higher, adds plastic processing
Cost.And the micro condensation water for being contained in plastic pellet bubble is difficult to remove.
The purpose of the present invention is disclosing a kind of chemical water-eliminating method of plastics, it is to utilize deicer, passes through chemical reaction
Mode, absorbs micro-moisture contained in plastics and is combined to novel substance, and removes the moisture in plastics.
The water-eliminating method is that secondary operation is directly carried out after deicer is mixed with plastics, without special drying equipment,
Save time and power, easy to use, the plastics water removal suitable for opaque plastic product secondary processing process.
The content of the invention
The present invention is realized by the technical solution of following technical measures composition.
The present invention discloses a kind of preparation method of plastics deicer.The plastics deicer is by anhydrous calcium oxide micro mist three
（Dioctyl pyrophosphoryl epoxide）Isopropyl titanate, ethylene-vinyl acetate copolymer and low molecular weight polyethylene, by melting mixing
Made of extruding pelletization.The percentage by weight of the deicer each component is：
Anhydrous calcium oxide micro mist 70-83%
Three（Dioctyl pyrophosphoryl epoxide）Isopropyl titanate 1-3%
Ethylene-vinyl acetate copolymer 15-25%
Low molecular weight polyethylene 1-2%
The anhydrous calcium oxide micro mist in the above-mentioned technical solutions, is to smash anhydrous calcium oxide into particle diameter at 100-110 DEG C
Micro mist less than 10 microns, the preferred scope of its weight percentage is 70-80%；Three（Dioctyl pyrophosphoryl epoxide）Metatitanic acid is different
Propyl ester purity is technical grade, its weight percentage general control is in 1.5-2.5%；Low molecular weight polyethylene molecular weight is less than
3000, its weight percentage general control is in 1.5-2%.
A kind of preparation method of plastics deicer disclosed by the invention：Anhydrous calcium oxide micro mist is added and has warmed up 100-
In 110 DEG C of super mixer, three are added（Dioctyl pyrophosphoryl epoxide）Isopropyl titanate, high-speed stirred 2-3 minutes, adds
Ethylene-vinyl acetate copolymer, high-speed stirred 2 minutes.Double-screw extruding pelletizing machine is added after releasing, in 120-160 DEG C of temperature
Lower melting extrusion is granulated, and the particle that will eventually cause is put into super mixer, is added low molecular weight polyethylene, is stirred at 120 DEG C
Mix 1-2 minutes, plastics deicer.
A kind of plastics deicer disclosed by the invention, it is a kind of chemical water-eliminating method, it, which removes water principle, is：
Anhydrous calcium oxide micro mist in deicer, the water run into plastics chemically react, and generation one kind can be filled out as plastics
The material calcium hydroxide of charge, so as to eliminate the moisture in plastics, i.e. CaO+H2O→Ca(OH)2.
A kind of plastics deicer disclosed by the invention, application method are to add the deicer of 1-5% in the plastic, are uniformly mixed
Afterwards, it is directly used in the melting extrusion processing of plastic products.Deicer can also be mixed with plastics it is even after, first make once grain, then
The processing of plastic products is carried out, simple and convenient using the deicer, not power consumption, does not take.Being processed into for plastic products can be reduced
This.
