Description
Technical Field
The invention relates to the technical field of composite materials, in particular to a high-performance nano oxide composite material and a preparation method and application thereof.
Background
Polystyrene is a synthetic rubber using ethylene and propylene as main monomers, and has excellent properties that many other general synthetic rubbers do not have, and the monomers are cheap and easily available, so that it is widely used in the fields of tapes, films, automobile parts, building materials and other products.
The main disadvantages of polypropylene are the slow vulcanization rate, the difficulty of incorporation into other unsaturated rubbers, the poor self-adhesion and mutual adhesion, and the poor processability. Accordingly, commercially commonly used polypropylene materials are generally composite materials mixed with other materials. However, in industrial production, physical modification is commonly used, i.e. elastomer, organic or inorganic rigid particles are added into the formula of the polypropylene product, and then the product is obtained by melt blending.
And when the polypropylene-ethylene composite material is applied to closed spaces such as indoor spaces or vehicle interiors, the pollution problem of indoor environments, particularly the formaldehyde pollution problem, is the most concerned problem. The current formaldehyde treatment modes mainly comprise active carbon physical adsorption, photocatalytic oxidation, plasma decomposition, chemical reaction, biodegradation and the like. Wherein, the physical adsorption treatment effect of the charcoal is poor; the operation processes of photocatalytic oxidation, plasma decomposition and biodegradation are more complicated and the cost is high; therefore, the chemical reaction has the advantages of widest application range, highest efficiency and low cost. However, the spraying of chemical agents to the surfaces of indoor environment, furniture and the like may leave marks on the furniture surface, even the furniture surface may be damaged in severe cases, and the chemical agents are scattered in the air during the spraying process, which is easy to cause secondary pollution to the indoor air.
Disclosure of Invention
The invention aims to solve the technical problem of providing a high-performance nano oxide composite material, a preparation method and application thereof, and solves the problems of poor comprehensive performance and the like of the existing polypropylene-ethylene composite material when used in an indoor environment.
In order to solve the technical problems, the technical scheme of the invention is as follows:
one of the purposes of the invention is to provide a high-performance nano oxide composite material, which is prepared from the following raw materials:
polypropylene ethylene, titanate coupling agent, nano calcium carbonate, ethylene urea, calcium stearate and solvent;
the components are calculated according to the parts by weight:
the smaller the particle size of the calcium carbonate is, the more uniform the calcium carbonate is dispersed in the resin, and the better the toughening effect on the resin is, so that the adopted nano calcium carbonate can play an effective toughening and modifying role in the polypropylene ethylene; and calcium stearate as an auxiliary agent can play a role in lubrication to reduce the viscosity of the material, and the melt fracture is reduced by enhancing the melt strength of the polypropylene-calcium carbonate composite material, so that the precipitation of the material is improved.
Preferably, the components are calculated according to parts by weight:
preferably, the solvent is at least one of toluene, dichloromethane and diethyl ether.
The second purpose of the invention is to provide a preparation method of a high-performance nano oxide composite material, which comprises the following steps:
(1) Modification of nano calcium carbonate: dissolving the titanate coupling agent in parts by weight in a solvent, heating to 40-60 ℃, adding the nano calcium carbonate, fully stirring, filtering, drying, crushing and sieving to obtain modified nano calcium carbonate;
(2) And mixing, heating and melting the polypropylene, the ethylene urea, the calcium stearate and the modified nano calcium carbonate in parts by weight, and cooling to obtain the composite material.
After the nano calcium carbonate is modified, the interfaces between the polypropylene ethylene, the calcium carbonate and the titanate coupling agent have interaction, and the interaction can absorb more energy when the matrix polypropylene ethylene is subjected to yield and plastic deformation, so that the effects of strengthening and toughening are finally achieved.
Preferably, the nano calcium carbonate is added in the step (1) and fully stirred for reaction for 2 to 3 hours.
Preferably, the parts by weight of the polypropylene, the ethylene urea, the calcium stearate and the modified nano calcium carbonate in the step (2) are mixed and heated to 200-300 ℃, and are stirred and melted.
The invention also aims to provide a fiber material prepared from the high-performance nano oxide composite material, which is prepared by dissolving the composite material in a polar solvent, standing the mixture until bubbles are eliminated, and then carrying out electrostatic spinning.
Preferably, the polar solvent is at least one of N, N-dimethylformamide, tetrahydrofuran and ethyl acetate.
Preferably, the composite material is dissolved in a polar solvent to prepare a solution with the mass fraction of 10% -20%, and the solution is kept stand for 2-3 hours.
Preferably, the electrostatic spinning conditions are that the voltage is 20-30kV, the receiving distance is 10-15cm, and the spinning speed is 0.5-2mL/h.
Ethylene has an active group which reacts with formaldehyde, can capture formaldehyde to cause an aldehyde elimination reaction, and can be used as a formaldehyde capture agent. The fiber material is loaded with the ethylene urea capable of capturing formaldehyde for use, so that the fiber material is a very safe and healthy use mode. On one hand, the harm to furniture and indoor environment caused by spraying of the ethylene urea can be avoided, and on the other hand, the fiber or fabric material has a large specific surface area, so that the ethylene urea can be fully spread to ensure that formaldehyde molecules and the ethylene urea are fully contacted.
By adopting the technical scheme, the nano-scale calcium carbonate is modified, so that the reinforcing and toughening effects of the polypropylene can be greatly improved; and the ethylene urea is loaded on the fiber material of the electrostatic spinning, so that the forming is convenient, the specific surface area is high, formaldehyde gas can be adsorbed, the efficiency of removing formaldehyde by ethylene urea chemistry is improved, and the functional nanofiber membrane for efficiently purifying formaldehyde can be prepared.
