Abstract
The invention provides a low-odor general plastic and the preparation method thereof. The low-odor general plastic is composed of general plastic, a modifier, an antioxidant, a lubricant, a BX molecular sieve and active aluminum oxide. Generally, the preparation method comprises the following steps: weighting materials at a certain ratio, adding the materials into a high-speed mixer, mixing the materials thoroughly, and extruding and granulating the materials by a double-screw extruder. The method has the advantages that the odor of the general plastic is reduced, while the original properties of the general plastic are maintained.
Description
Technical field
The present invention relates to general-purpose plastics of a kind of low smell and preparation method thereof.
Background technology
General-purpose plastics is meant generally that output is big, purposes is wide, good moldability, low-cost plastics.General-purpose plastics has five big kind, i.e. polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS.They have light weight, chemical stabilization, can not corrosion, good shock-resistance, wear resistant, good insulation, lower thermal conductivity, formability, good tint permanence and lower advantages such as tooling cost preferably preferably, thereby be widely used in each field of society such as mechanical industry, automotive industry, electronic apparatus industry, instrument and meter industry, textile industry and building industry, be the material of present usage quantity maximum.
, general-purpose plastics becomes the material of present usage quantity maximum though having the performance of a lot of brilliances; but because general-purpose plastics has certain volatility mostly; goods commonly used in use often produce certain volatile matter; can produce certain emanation on the product surface; influence the use of product; also produce certain bad smell simultaneously, to air---particularly the Air quality of some interior spaces exerts an adverse impact, and user's health and environment protection caused certain infringement.Along with more and more higher to people's environment protection and physically and mentally healthy requirement; general-purpose plastics is because the bad smell that its volatility causes makes it in use produce detrimentally affect to people's health and environment protection; this development to general-purpose plastics forms certain hidden danger, therefore needs its smell is detected and controls.
Summary of the invention
The purpose of this invention is to provide general-purpose plastics of a kind of low smell and preparation method thereof, make and when keeping the general-purpose plastics primary characteristic, reduce the smell of general-purpose plastics.
In order to achieve the above object, the general-purpose plastics of a kind of low smell provided by the invention, it is characterized in that, form: general-purpose plastics 65%～85%, properties-correcting agent 14.4%～32.75%, oxidation inhibitor 0.1%～0.5%, lubricant 0.1%～0.5%, BX molecular sieve 0.2%～0.5%, activated alumina 0.2%～0.75% by following weight percent raw material.
Described general-purpose plastics is a kind of in PP plastics, ABS plastic, PVC plastics, PE plastics, the PS plastics; Described properties-correcting agent is a kind of in N-phenylmaleimide, TDE or the polyethylene glycol system polymeric amide; Described oxidation inhibitor is to be that 1: 1～1: 3 Hinered phenols antioxidant and phosphite ester kind antioxidant mix at normal temperatures and pressures and form with weight ratio; Described Hinered phenols antioxidant is 2,2 '-methylene-bis-(4-methyl-6-tert butyl phenol) 2246,4,4 '-thiobis (6-tertiary butyl meta-cresol) 300, butylated hydroxy-a) a kind of among the BHT; Described phosphite ester kind antioxidant is two (2.4-di-tert-butyl-phenyl) pentaerythritol diphosphites 626, distearyl pentaerythritol diphosphite 618, four (2, the 4-di-tert-butylphenol)-4, a kind of among 4 '-xenyl diphosphites P-EPQ; Described lubricant is N, N '-ethylenebisstearamide EBS.
A kind of preparation method of general-purpose plastics of low smell is characterized in that, comprises the following steps:
Step 1, take by weighing various raw materials respectively by weight percentage;
Step 2, at normal temperatures and pressures is with above-mentioned materials in super mixer 200 rpms, thorough mixing 3min～5min;
Step 3, will place the twin screw extruder extruding pelletization by the raw material that step 2 obtains.
Twin screw extruder length-to-diameter ratio described in the step 3 is 40: 1, screw speed is at 100-500 rev/min, it is 130 ℃-260 ℃ in a district that its twin screw is extruded working temperature, 140 ℃-270 ℃ in two districts, 150 ℃-280 ℃ in three districts, 150 ℃-280 ℃ in four districts, 150 ℃-280 ℃ in five districts, 150 ℃-280 ℃ in six districts, 150 ℃-280 ℃ in seven districts, 150 ℃-280 ℃ in eight districts, residence time 1-2 minute.
All there are a large amount of holes in BX molecular sieve and activated alumina, have very large specific surface area, can carry out selective adsorption to molecule according to the size in crystals hole, promptly adsorb a certain size molecule and repel the molecule of big material.They can both well mix with general-purpose plastics, in plastic substrate, can disperse relatively evenly, and durable, the high temperature of anti-processing, add man-hour this composite sorbent material and can well adsorb the small molecules volatile matter when extruding, these small molecules volatile matters are adsorbed on the inside, what make that these volatile matters can be stable is retained in the resin and can not disperses out, thereby can be good at reducing the smell of plastics.Properties-correcting agent can give plastics certain specific function.The effect of lubricant is the flowability that has improved materials processing, has reduced coefficient of friction, improves the smooth property of resin, improves surface luster.
Advantage of the present invention is when having kept the general-purpose plastics primary characteristic, has reduced the smell of general-purpose plastics.
