Description
Technical field
The invention belongs to component and the formula of matrix material, especially a kind of refuse bag film additive and preparation method thereof; The invention still further relates to the refuse bag film using this refuse bag film additive as auxiliary agent.
Background technology
Polyethylene refuse bag film be China so that in the world refuse classification packaging important materials, its annual production can reach more than 10 ten thousand tons, is widely used in the refuse classification process of various countries, is extremely important green material.According to concerned countries standard, this type of refuse bag film is necessary for black, and carbon content should reach or higher than 2.5%.All add carbon black colour batch at present.In plastic garbage bag film, add carbon black can play certain covering and coloring effect.But the expensive and difficulties in dispersion of carbon black, the high and contaminate environment of production energy consumption.And particle diameter is too small, the excessive surface energy that causes of specific surface area is very big, very easily reunites, belongs to function surplus.Not only affect result of use, also make cost up.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of raw material and the refuse bag film additive reasonable, cost is low, dispersion effect is good of filling a prescription.
Another technical problem to be solved by this invention there is provided the preparation method of above-mentioned refuse bag film additive.
Another technical problem to be solved by this invention there is provided and uses the refuse bag film that above-mentioned refuse bag film additive is auxiliary agent.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is a kind of refuse bag film additive, and be characterized in, this additive is made up of the raw material of following weight proportion:
Particle diameter is not more than the microfine coal 100 parts of 10 microns;
Wollastonite powder 60 ~ 100 parts;
Titanate coupling agent 0.1 ~ 1 part;
Aluminate coupling agent 0.1 ~ 1 part;
Dispersion agent 0.1 ~ 8 part;
High density polyethylene(HDPE) 10 ~ 20 parts;
LLDPE 10 ~ 20 parts;
Described dispersion agent is selected from stearates, stearyl amine, metal soap, fatty acid ester, amphoterics class dispersion agent.
In refuse bag film additive technology scheme of the present invention, the weight proportion of each raw material is preferably:
Particle diameter is not more than the microfine coal 100 parts of 10 microns;
Wollastonite powder 75 ~ 85 parts;
Titanate coupling agent 0.4 ~ 0.8 part;
Aluminate coupling agent 0.4 ~ 0.8 part;
Dispersion agent 0.4 ~ 0.8 part;
High density polyethylene(HDPE) 13 ~ 17 parts;
LLDPE 13 ~ 17 parts;
In refuse bag film additive technology scheme of the present invention, described dispersion agent is preferably polyethylene wax or paraffin.
The invention also discloses a kind of preparation method of the refuse bag film additive as described in above technical scheme, be characterized in: in ball mill, add the raw material except high density polyethylene(HDPE), LLDPE in proportion, 60-195 DEG C, 100-200RPM operates 10-60 minute, add all the other raw materials in proportion again, add twin screw extruder granulation after mixing, after cooling, packaging gets product.
Present invention also offers a kind of refuse bag film, be characterized in: the refuse bag film additive that this film employs in above technical scheme described in any one is auxiliary agent, or employing the refuse bag film additive that above-described preparation method obtains is auxiliary agent, and the weight proportion of each raw material is:
High density polyethylene(HDPE) 50 ~ 100 parts;
LLDPE 0 ~ 40 part;
Modified super-fine cool-ash refuse bag film PP Pipe Compound 2 ~ 30 parts.
Wherein: the weight part of raw material LLDPE is preferably 10-40 part.
Inhaling refuse bag film for this can adopt ordinary method to prepare, the typical production technique horizontal inflation film manufacturing machine in low center, the temperature of processing is 100 ~ 190C °, product folding 400 ~ 1000 millimeters, the footpath obtained through aforesaid method, the black thin film of thickness 0.01 ~ 0.05 millimeter.Be finished product.
Refuse bag film additive of the present invention overcomes the deficiency using carbon black, as used the excessive surface energy that causes of the too small carbon black of particle diameter, specific surface area very big, very easily reuniting, belonging to function surplus, cost up.Refuse bag film additive carbon content of the present invention can be greater than 30%, and price is no more than 5000 yuan/ton, while quality product is up to state standards, makes whole formulation cost ratio look mother reduce by more than 4%.It is used in polyethylene refuse bag film, the uniform black of refuse bag film, enough hiding rares can be given and improve tear strength, expensive polyvinyl resin can be saved.The quality of refuse bag finished film and production technique are all unaffected.The more important thing is: the coal dust added and wollastonite can avoid the wall cling phenomenon of the polyethylene refuse bag when burning effectively, guarantee complete environmental protection of burning.
Compared with prior art, technique effect of the present invention is mainly manifested in: the tear strength that effectively can improve plastic garbage bag film after the present invention utilizes refuse bag film additive, and can reduce costs, and increases economic efficiency.The simultaneously environmental pollution that brings of carbon black capable of reducing using, the coal dust of interpolation and wollastonite can avoid the wall cling phenomenon of the polyethylene refuse bag when burning effectively, guarantee that burning completely, save energy.Meet the megatrend of low-carbon economy.
