Abstract
The invention discloses a fully degradable garbage bag composite material and a preparation process thereof. The composite material is characterized by comprising the following components in parts by weight: 55-65 parts of corn starch, 18-23 parts of polyvinyl alcohol, 8-12 parts of glycerin, 4-6 parts of ethylene glycol, 2-4 parts of urea and 5-7 parts of organo-montmorillonite. The composite material disclosed by the invention has good dispersibility, maintains the original longitudinal and lateral tension properties, and has good promotion value.
Description
Technical field
The present invention relates to refuse bag and prepare the material technology field, relate to the compound fully degraded refuse bag material of a kind of starch/PLA in particular.
Background technology
POLYACTIC ACID (PLA) is a kind of novel biodegradable material, and the starch material that uses reproducible plant resources (like corn) to be proposed is processed.The extrusion grade resin is the main application of PLA, is mainly used in fresh vegetables and fruits packing in the large supermarket, and such packing has become the important a member in the chain of European market; Next is used for some electronic product of advocating safety, energy-saving and environmental protection packings.Advantage applies such as PLA high-clarity, high glossiness, high rigidity get incisively and vividly in these purposes, have been at present the dominant direction that PLA uses.In addition, the application of extrusion grade resin on gardening also begins to obtain to pay attention to, and fields such as the greening on the slope, sandstorm improvement are existing at present uses.Like one Chinese patent application number is CN200910212940.6; Denomination of invention is to be used for polyethylene modified material of degradable garbage bags and preparation method thereof; Its component is: W-Gum 25%～35%, high density polyethylene(HDPE) 60%～70%, polycthylene grafted maleic anhydride 5%～10%.Preparation technology: earlier W-Gum, high density polyethylene(HDPE), polycthylene grafted maleic anhydride are mixed in high-speed mixer; Mixture plastifies in twin screw extruder, mixing, through extruding, obtain being used for after the cooling, pelletizing the polyethylene modified material of degradable garbage bags.The refuse bag outward appearance that this patent system gets is yellowish transparent, shows bright and cleanly, but degradation capability is general, and physical strength is not enough, is difficult to satisfy the demand in market.
Summary of the invention
The object of the invention is exactly a kind of not only good dispersibility that provides for the deficiency that solves prior art, keeps original performance to pulling force in length and breadth, and has the compound fully degraded refuse bag material of environment-friendly function.
Another object of the present invention provides a kind of preparation technology of compound fully degraded refuse bag material.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of compound fully degraded refuse bag material is characterized in that its component and part by weight umber ratio comprise:
W-Gum 55-65 part
Z 150PH 18-23 part
Glycerine 8-12 part
Terepthaloyl moietie 4-6 part
Urea 2-4 part
Organo montmorillonite 5-7 part.
As further specifying of such scheme: the component of said refuse bag material and part by weight umber are preferred:
60 parts of W-Gums
20 parts of Z 150PH
10 parts of glycerine
5 parts of terepthaloyl moietie
3 parts in urea
6 parts of organo montmorillonites.
A kind of preparation technology of compound fully degraded refuse bag material is characterized in that it comprises the steps:
At the horizontal high-speed mixing machine, the heating middling speed was mixed 25-35 minute with W-Gum for a, elder generation;
B, add Z 150PH, mixed at high speed 10-20 minute;
C, the mass transport that mixes arrive screw discharging kneader;
D, adding glycerine, terepthaloyl moietie, urea, the mixing plasticizing of high speed;
E, add organic polynite;
F, extruding pelletization;
G, finished product packing.
In said process step a process, the heating middling speed was mixed mixed powder water cut < 2% 30 minutes.
In the mixed at high speed process of said process step b, mixed at high speed 15 minutes.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, matrix material of the present invention fully can ordinary production on traditional blown film machine.
2, good dispersibility keeps original performance to pulling force in length and breadth.
3, reach environment-friendly function.
