Abstract
The invention relates to a method for preparing a damping material through waste polystyrene foam plastics and waste gelatine powder. The method can prepare environmental functional material products with excellent damping characteristics through the processes of preparing a mixed solvent, modifying the waste polystyrene foam plastics, preprocessing the waste gelatine powder, milling and curing. The method which has a simple process, low production cost and little equipment investment is an ideal way to comprehensively utilizing the waste polystyrene foam plastics and waste gelatine powder and changing the waste into the valuable. As the products prepared through the method have good safety, a wider frequency damping platform area and a temperature damping platform area, the products are applicable to the damping and acoustic insulation for vehicles, ships, engineering machineries, buildings, etc. Specific products can also be made through determining the parameters of the damping products according to the actual demand.
Description
Technical field
The present invention relates to utilize waste polystyrene foam plastic and shoddy to make the method for damping material, especially utilize the preparation of deposed polystyrene and waste rubber to have the method for the environment functional material of good damping characteristic.
Background technology
Annual deposed polystyrene and the waste rubber enormous amount that produces of China is referred to as " white garbage " and " black rubbish " by people, the conversion of can not rotting can not be degraded voluntarily again and disappeared.Landfill that past adopts and incineration treatment method be contaminate environment not only, and the waste resource, has not met the requirement of modern conservation-minded society development.How reasonably, recycle the generally attention that waste polystyrene foam plastic and waste rubber have caused China and countries in the world researcher effectively.About many patents and research report have successively appearred in reuse of Waste Polystyrene Foams, the technology of recyclable multiple plastics is arranged, the technology of the single resin of special recovery is also arranged.China's waste rubber is used based on projects such as reclaimed rubber, rubber powder and tyre retreading at present.The reclaimed rubber energy consumption is big, to serious environment pollution, is subjected to the restriction of environmental protection factor more, and tyre retreading output is significantly increased by the difficulty that influences of all factors also.Shoddy is mainly used in industries such as modifying asphalt, road pavement and paving sports field rubber item at present.
Damping material has obtained very using widely in a lot of fields, utilize these two kinds of high molecular waste materials of polystyrene foamed plastics and rubber to prepare damping material, both can solve the noise problem that influences people, overcome the disadvantageous effect that noise, vibration and impact cause human environment and engineering circle, it can be utilized again, save resource, become " giving up " into precious.
The research of preparation blend damping material mainly comprises interpenetrating polymer networks (IPN) damping material, elastomer alloy cushioning material etc.But preparation above-mentioned materials cost height, technical process is long, has influenced the application of waste polystyrene foam plastic and shoddy resource utilization greatly.Therefore, be the novel damping material of development of raw materials with such waste, it is extremely urgent to promote the marketization to use.
Summary of the invention
The object of the present invention is to provide a kind of method of utilizing waste polystyrene foam plastic and shoddy to prepare damping material, it is to utilize waste polystyrene foam plastic and two kinds of waste material preparations that do not have fine damping characteristic of shoddy itself to have the method for the functional materials of good damping capacity.
Another object of the present invention is to have the functional materials product of good damping capacity with method for preparing.
The method of utilizing waste polystyrene foam plastic and shoddy to prepare damping material provided by the invention is as follows:
1. preparation mixed solvent: ethyl acetate and acetone are mixed with the mixed solvent that is used for the swelling deposed polystyrene by mass ratio 3:1～4:1.
2. modification deposed polystyrene; Deposed polystyrene and mixed solvent with mass ratio 1:1～1.5:1 swelling, are added Resins, epoxy, and its quality is no more than waste polystyrene foam plastic 1/3rd, stirs 30min at 70 ℃ of following condensing refluxes, and it is material modified to make deposed polystyrene.
3. pre-treatment shoddy: shoddy was plasticated in mill 10-20 minutes, utilize the shear action of mill that the small molecules segment is torn in the rubber powder granule fragmentation.
4. calendering process: shoddy is through after the pre-treatment, per 100 gram shoddies add modified polystyrene 10～30 grams, viscosity increaser 5 grams, scorch retarder 0.5 gram, anti-aging agent 0.5 gram, promotor 1 gram, activator 1 gram, vulcanizing agent 1 gram successively, each reagent is a kind of reagent under mixing even back adds, up to slice.
5. sulfuration process: will refine good film cutting and put into 2 mm thick moulds, sulfidization molding on the compression molding instrument.Pressure 0.1-0.25MPa, 120～140 ℃ of temperature, 10～30 minutes time.
The method of utilizing waste polystyrene foam plastic and shoddy to prepare damping material provided by the invention, operating procedure is simple, and production cost is low, and facility investment is few, is the desirable approach that comprehensive utilization waste polystyrene foam plastic and shoddy are turned waste into wealth.
The damping material that utilizes the preparation of waste polystyrene foam plastic and shoddy provided by the invention, by DMA scanning temperature test, can obtain damping value is 50～70 ℃ greater than the △ T of 0.3 damping platform area, the damping peak value is 0.36～0.60; By DMA sweep rate test, can obtain damping value is 120～160HZ greater than 0.5 damping platform area △ HZ, and the damping peak value is 0.44～0.65.This product has the frequency damping platform area and the temperature damping platform area of broad, security is good, be applicable to damping sound insulation aspects such as vehicle, naval vessel, engineering machinery and buildings, also can determine the parameter of damped products according to actual needs, to determine the processing specific product.
