Abstract
The invention relates to an organic glass tube which is prepared from the following raw materials by weight ratio: 80-210 of methyl methacrylate, 0.02-0.03 of azodiisobutyronitrile, 0.02-0.03 of peroxide carbonic acid diisopropyl ester, 5-8 of dibutyl phthalate and 0.5-2 of stearic acid. The monomer methyl methacrylate is used as a basic raw material, and a polymethyl methacrylate tube produced with a mass centrifugal polymerization method is the organic glass tube. The transparency of the organic glass tube is high, the light transmittance is larger than 92 percent and is over 10 percent higher than that of silica glass, the refractive index is 1.49, and the relative density is only 1.18. The organic glass tube has good toughness and ageing resistance, and the thermal decomposition temperature is larger than 200 DEG C. The operating temperature is at most 80 DEG C, the organic glass tube can resist chemical medicine such as dilute acid and alkali, oil and the like.
Description
Technical field
The present invention relates to a kind of tubing, particularly the good plexi-glass tubular of a kind of transmittance.
Background technology
When making teaching and advertising model, artwork and instrument, need to use transparent pipeline, plastic pipe of the prior art, its transparency is low, the printing opacity rate variance, and aging low with acid-proof alkaline easily.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, has proposed a kind of acid and alkali-resistance, has been difficult for the aging good plexi-glass tubular of transmittance.
The technical problem to be solved in the present invention is achieved through the following technical solutions, and the plexi-glass tubular that a kind of transmittance is good is characterized in: it is to be made by the raw material of following weight proportion,
Methyl methacrylate 80 ~ 120
Urethane 7 ~ 8 is closed in insatiable hunger
Poly-to stupid dioctyl phthalate glycol ester 0.02 ~ 0.03
Diisopropyl azodicarboxylate 0.02 ~ 0.03
Peroxy dicarbonate diisopropyl fat 0.02 ~ 0.03
Stearic acid 0.5 ~ 2.
The present invention compared with prior art, take monomers methyl methacrylate as basic raw material, the polymethylmethacrylate pipe that adopts body centrifugal polymerization method to produce, it is plexi-glass tubular, its transparency is high, transmittance is greater than 92%, and on high 10% of silex glass, refractive index is that 1.49 relative densities only are 1.18.Plexi-glass tubular of the present invention has excellent toughness and ageing resistance, and heat decomposition temperature is greater than 200 ℃, when use temperature is no more than 80 ℃, and can the alkali of anti-the diluted acid, the pharmaceutical chemicals such as grease.
Embodiment
A kind of plexi-glass tubular, it is to be made by the raw material of following weight proportion,
Methyl methacrylate 80 ~ 120
Urethane 7 ~ 8 is closed in insatiable hunger
Poly-to stupid dioctyl phthalate glycol ester 0.02 ~ 0.03
Diisopropyl azodicarboxylate 0.02 ~ 0.03
Peroxy dicarbonate diisopropyl fat 0.02 ~ 0.03
Stearic acid 0.5 ~ 2.
The preparation method of plexi-glass tubular of the present invention is dissolved in the initiator Diisopropyl azodicarboxylate first in half the methyl methacrylate monomer for subsequent use; Second half methyl methacrylate monomer is added in the batching kettle, add again above-mentioned methyl methacrylate monomer, peroxy dicarbonate diisopropyl fat, dibutyl phthalate (DBP), the stearic acid that is dissolved with initiator, stir miscible rear filtration and send in the prepolymerization kettle, be heated to 85 ℃ under stirring, begin polymerization and emit heat this moment, when treating that material is warming up to 90 ~ 91 ℃, stopped heating is used water coolant instead, keeps temperature in the kettle in 94 ℃, reacted 8 ~ 10 hours, and reached till the viscosity requirement; Pre-polymerization slurry in the prepolymerization kettle is cooled to below 30 ℃, and it is for subsequent use to be discharged to storage tank; Above-mentioned pre-polymerization slurry is slowly poured in the mould pipe of having sealed by calculated amount, then seal the material filling end, and reserve two apertures at end cap, in order to fill nitrogen and exhaust, fill the nitrogen exhaust after 10 ~ 15 minutes, totally-enclosed end cap is contained in the mould pipe on the horizontal centrifugal turret mount immediately, the heated polymerizable while turning round is bathed as thermal source with water-bath or warm air; After polymerization, obtain the polymethylmethacrylate pipe.Polymerization time and temperature are different with the specification of pipe, and present method is applicable to the pipe wall thickness less than 5mm.
Among the above-mentioned preparation method, the mould pipe is contained on the horizontal centrifugal turret mount, while turning round in the process of heated polymerizable, when behind the goods wall between 2.5 ~ 5mm the time, needs forced convection, wind speed 2 ~ 4m/s.When behind the goods wall less than 2.5mm the time, hot blast can be without forced convection in the baking oven.
