In the proportionlity of experiment PetroChina Company Limited.'s resin and SEBS, the proportionlity of naphthenic oil and dibutyl phthalate.
, be the dissolving of trace at first with the molten a spot of petroleum resin of butyl glycol ether of 5 grams.A spot of naphthenic oil can dissolve fully.The molten a spot of dibutyl phthalate of butyl glycol ether with 5 grams can dissolve fully.Petroleum resin and SEBS good dissolving not in butyl glycol ether is described thus, and the good dissolving in butyl glycol ether of naphthenic oil and dibutyl phthalate.Just can judge proportionlity between naphthenic oil and the petroleum resin by butyl glycol ether dissolving naphthenic oil and dibutyl phthalate; Can get ratio between SEBS and the petroleum resin by dimethylbenzene.
1) get a beaker, claim 3 gram dimethylbenzene to pour 10 gram SEBS and 10 gram petroleum resin into the beaker heating again, dissolving evenly.Get part and be placed on the iron plate, number No. 1 as sample.
2) get a beaker, claim 4 gram dimethylbenzene to pour 20 gram SEBS and 10 gram petroleum resin into the beaker heating again, dissolving evenly.Get part and be placed on the iron plate, number No. 2 as sample.
3) get a beaker, claim 6 gram dimethylbenzene to pour 30 gram SEBS and 10 gram petroleum resin into the beaker heating again, dissolving evenly.Get part and be placed on the iron plate, number No. 3 as sample.
4) get a beaker, claim 8 gram dimethylbenzene to pour 40 gram SEBS and 10 gram petroleum resin into the beaker heating again, dissolving evenly.Get part and be placed on the iron plate, number No. 4 as sample.
5) get a beaker, claim 10 gram dimethylbenzene to pour 50 gram SEBS and 10 gram petroleum resin into the beaker heating again, dissolving evenly.Get part and be placed on the iron plate, number No. 5 as sample.
6) get a beaker, claim 12 gram dimethylbenzene to pour 60 gram SEBS and 10 gram petroleum resin into the beaker heating again, dissolving evenly.Get part and be placed on the iron plate, number No. 6 as sample.
Viscosity is big when restraining petroleum resin with the molten 6 gram SEBS10 of 12 gram dimethylbenzene, so terminating operation.
Put into the baking oven of 50 ℃ of temperature controls will being taken at 6 samples on the iron plate, dried by the fire 24 hours, dimethylbenzene is dried, observe intensity, separability, the transparency of each sample then, by careful observation, have only sample 3. 4. suitable, so can reach a conclusion: the ratio of SEBS and petroleum resin has been given play to best effect between 3: 10 and 4: 10.
Stirring velocity is to the influence of the transparency of reactant quality and sample in the engineering test process.
In the engineering test process, if can cause melting inhomogeneous, fusing time too slowly and increase to stir and easily reactant is adhered on the walls of beaker too soon if stir, the quality of reactive material is changed, also can produce a large amount of bubbles simultaneously, thus the influence transparency.
Along with the speed that stirs is fast more, the quantity that bubble produces is many more, so control the speed that stirs well, preferably per second 3-4 changes, so not only can reduce the generation of bubble but also can not influence the quality of reactive material, make the result who draws at last more accurate, the sample transparency that draws during discharging simultaneously also can become excellent.
The problem that technology in the engineering test process (reinforced order) exists.
At first be that single test is understood the dissolving situation of petroleum resin in naphthenic oil, understand the dissolving situation of petroleum resin at dibutyl phthalate.
The process that petroleum resin melt in naphthenic oil: get 20 gram naphthenic oils and put into heating and stirring in the beaker, in the time of temperature T=100-130 ℃, add 47 gram petroleum resin, increase along with petroleum resin, solubleness also increases thereupon, viscosity also slowly begins to increase, and stirring can promote the dissolving of petroleum resin.After petroleum resin added, petroleum resin are swelling before this, and then fusing.Reduce temperature T=100 a little increase of ℃ viscosity behind the petroleum resin fusing homogeneous, a large amount of bubbles are arranged.With metal bar sampling, the sample of taking-up can moulding, transparency is better, and a little difficulty of touching with one's hand is peeled off.Set time is more suitable, solidifies cooling and retrodeviates crisp.
Petroleum resin take out 20 gram dibutyl phthalates and put into heating and stirring in the beaker in the melting process of dibutyl phthalate, add 47 gram petroleum resin in the time of T=100-130 ℃ slowly, and petroleum resin are swelling before this, and then fusing.Burn-off rate is slower in the time of T=100-130 ℃, but has the cigarette of trace to produce.With metal bar take out the sample insufficient formability, tack-free, difficulty is peeled off.
SEBS is dissolution process in naphthenic oil: get 30 gram naphthenic oils, add the SEBS of 13 grams in the time of intensification T=140 ℃ slowly, stir fusing, a spot of cigarette is arranged in the time of intensification T=150 ℃; Dress was rolled into a ball in the fusing of SEBS in naphthenic oil before this, had a large amount of particles not melt, and the melt-through elapsed-time standards is longer, and with the metal bar sampling, the sample plasticity of taking-up is good, separability is good, stick hand slightly, transparency is good.
SEBS gets 30 gram B liquid and puts into heating and stirring in the beaker at the dissolution process of dibutyl phthalate, if in slowly with 13 gram SEBS beakers, SEBS is moistening rapidly in B, and dissolving rapidly.SEBS fuses that pasty state was opaque before this, and the fusing back becomes liquid transparency to improve.After temperature was controlled at 110-140 ℃ of fusing homogeneous, with the metal bar sampling, the sample solidifies time was long, and plasticity is bad.
Comprehensive above four but think experiment exam, petroleum resin melt in naphthenic oil comparatively fast, and petroleum resin can be gained in strength and viscosity, but have branch burn-off rate in dibutyl phthalate slower, and are easy to generate a spot of cigarette.The speed that SEBS melts in naphthenic oil is slower, and glass is good, and is flexible, transparent.SEBS is rapid in the dibutyl phthalate fusion, and moulding is bad.So comprehensively its advantage can draw reinforced order.At first add antioxidant, than infusible SEBS, after the dissolving evenly, add good molten petroleum resin again, use the viscosity of dibutyl phthalate regulator solution again with the naphthenic oil dissolving.The film that solution is coated with on object is thinner, thereby reduces use cost.
If in experimentation, overcome this four problems, just can extraordinaryly embody the advantages such as rippability, ageing resistance, weathering resistance of protective membrane, can have good protective action to metal objects simultaneously; When object deposit need not, the preservation object that anti-oxidation just can be good, object oxidation.When metal objects uses at any time, again can be directly with the film of parcel on it with the easy to do strip off of hand, not only convenient but also can protect object, anticorrosive, be that the protection metal objects is antirust, waterproof, the anti-best choice that corrodes.
