Technical field
The present invention relates to a kind of polypropylene nylon plastic alloy for asphalt packaging bag, belong to chemical technology field.
Background technology
Along with the increasing of country to the investments in highway building dynamics, the important materials in the road construction---the bituminous consumption is increasing.
Easily soften, be easy to seepage, property that adhesive power is strong because pitch has to be heated, its accumulating problem is a great problem of puzzlement highway construction department always.For addressing this problem, country is just ad hoc for this reason key research projects during " eight or five ", and this new asphalt packaging bag technology of development soft package of pitch has brought revolution for the bituminous accumulating.The appearance of soft package of pitch is with eliminating the Traditional Packing mode of bottled asphalt gradually, for the bituminous accumulating brings many facilities.
Soft package of pitch bag material in the market mainly is divided into papery and plastics two big classes.Papery packing bag cost is higher, reclaims to be difficult for, and consumes forest resourceies.Plastic packaging bag adopts materials such as polyolefine to make inexpensive easy recovery more.But still there is the performance deficiency of following all many-sides in the plastics soft wrapping bag of domestic production at present, thereby is unfavorable for the popularization of this great technical renovation: the low and high contradiction of pitch can temperature of the fusing point of (1) polyolefin plastics soft packaging bag: the can temperature of road bitumen is generally at 135-140 ℃; What at present domestic commercially available plastics soft wrapping bag was selected for use all is universal thermoplastics, as polyolefine, because of its fusing point low (about 120 ℃), is easy to break under 135-140 ℃ can temperature and causes that pitch leaks.(2) the high and low contradiction of bitumen construction temperature of the complete temperature of fusion of polyolefin plastics soft packaging bag: the construction temperature of road bitumen generally is controlled at below 170 ℃, in case pitch is because of crossing the thermal ageing performance depreciation; At present domestic commercially available plastics soft wrapping bag melts greatly fully about 180 ℃, and this plastics soft wrapping bag was difficult to fusing fully when temperature was lower than 170 ℃.(3) mechanical strength of polyolefin plastics soft packaging bag is lower: road bitumen is the unavoidable mechanical collision that takes place in can, storage and transport process, cause packing bag to be broken and cause that pitch leaks, therefore, plastic flexible package pitch all adopts and adds Polywoven Bag with anti-leak at present.During the road bitumen construction, or before asphalt melting, peel off and remove packing material, or behind asphalt melting, salvage and remove packing material, so that the construction of molten asphalt.But this brings inconvenience for again the construction of road bitumen, also easily causes environmental pollution.
Summary of the invention
Purpose of the present invention just provides a kind of polypropylene nylon plastic alloy of novel making soft package of pitch bag usefulness.It is higher that this polyblend fusing point is higher than pitch can temperature, fully temperature of fusion is lower than 170 ℃, mechanical strength, is applicable to the execution conditions of road bitumen fully.
The technical solution adopted for the present invention to solve the technical problems is: a kind of polypropylene nylon plastic alloy for asphalt packaging bag, form by following components in portion by weight: polypropylene 80-95 part, nylon 5-20 part, auxiliary agent 0.1-1 part, compatilizer 5-20 part.
Above-mentioned each component weight proportion is preferably: polypropylene 80-90 part, nylon 10-20 part, auxiliary agent 0.1-0.5 part, compatilizer 8-15 part.
Wherein, compatilizer is a graft modification polypropylene, and it is 8.5-9.5 with vinylbenzene (ST) ratio that the grafted monomer of employing is selected from MALEIC ANHYDRIDE (MAH) or glycidyl methacrylate (GMA) or glycidyl methacrylate (GMA): 1 mixture.The percentage of grafting of graft modification polypropylene is excellent with 1.5-3.5%.
Auxiliary agent is that ratio is initiator, degradation inhibitor and the carrier of 4-6: 1-2: 2-5 mixes gained under 110-120 ℃ of condition a product.Initiator is selected from dicumyl peroxide (DCP) or benzoyl peroxide (BPO) etc., and degradation inhibitor is an ethylene-propylene diene copolymer (EPDM) etc., and carrier is a layered silicate etc.The vinylbenzene (ST) that in auxiliary agent, also can add 1-10%.
Polypropylene is selected from any one in homo-polypropylene, Co-polypropylene, the modified polypropene etc., is excellent with homo-polypropylene.Homo-polypropylene such as F401, FC801, C1007 etc., Co-polypropylene such as F800E, C1608 etc., modified polypropene KB5060 etc.
Nylon is selected from any one in nylon 6, nylon 66, Ni Long11, the nylon 1010 etc.
Because polypropylene is a non-polar material, nylon is polar material, if these two kinds of materials are directly mixed mutually, they are very difficult compatible.Therefore, the affinity of giving polypropylene and nylon is one of key of present technique with reactivity.The present invention has solved the problem of polypropylene and nylon compatibility well, thereby has obtained uniform polypropylene nylon plastic alloy by adding an amount of compatilizer as adopting the graft polypropylene after MALEIC ANHYDRIDE etc. is carried out solid phase graft-modification in component.
The compatilizer graft polypropylene can be bought satisfactory product from the market; also can prepare by the following method: polypropylene is added in the helix agitator that is preheated to 110-120 ℃; when treating that the polypropylene temperature rises to 80 ℃ of left and right sides; add an amount of grafted monomer (monomeric add-on is about polypropylene weight 5-10%), and feed nitrogen protection.When the polypropylene temperature rises to temperature of reaction 110-120 ℃, gradation add total amount be the BPO of polypropylene weight 0.05-0.15% as catalyst for reaction, wait to add last BPO, react 30min again and finish.The product that obtains is placed baking oven, be the graft polypropylene product in dry about 2 hours down at 120 ℃.
In addition, the fusing point of general polypropylene nylon plastic alloy is 175-185 ℃, make this alloy being lower than fusion fully under 170 ℃ the temperature, is two of present technique key.Because the fusing point of macromolecular material is decided by its molecular weight size and molecular weight distribution, generally regulate its molecular weight size and molecular weight distribution by in material, adding certain auxiliary agent; But then, along with the adjusting to the polyblend molecular weight, the mechanical property of material also decreases.Therefore, how guaranteeing to guarantee the enough mechanical strengths of material when reducing temperature of fusion, is the another key of present technique.The present invention can regulate the molecular weight and the molecular weight distribution of polypropylene nylon plastic alloy by add appropriate amount of addition agent in component, reduces its melt temperature, guarantees that polypropylene nylon plastic alloy can be lower than fusion fully under 170 ℃ the temperature.Simultaneously, by adjusting the composition of auxiliary agent, (activation temperature of auxiliary agent and soak time are meant that initiator such as DCP or BPO decomposed for 50% required time at a certain temperature in the auxiliary agent for the activation temperature of control auxiliary agent and soak time, it is the transformation period, they are to be mutually related), the activation temperature of auxiliary agent and the preparation technology of soak time and graft polypropylene are complementary; And, reach the purpose that guarantees mechanics of materials intensity by adjusting the add-on of auxiliary agent.
With preparation graft polypropylene under 110 ℃ of conditions is example, corresponding therewith, under 110 ℃ of conditions, following component mixed and can make satisfactory auxiliary agent: 50% benzoyl peroxide, 10% vinylbenzene, 10% ethylene-propylene diene copolymer and 30% carrier layered silicate.Similarly, can under corresponding conditions, make the multiple auxiliary agent that contains different components that is complementary with the preparation technology of different graft polypropylenes.
