Abstract
The invention discloses a preparation process of a paper pouring earthenware pipe. The preparation process comprises the following steps: 1) wood fibers and a binding agent are put in a stirring device for uniformly stirring in a mass ratio of 5: 3 to prepare a mixture; 2) the mixture is put in an extruding device to extrude out a piece-shaped paper material with a thickness of 1-3 mm; 3) a layer of thermosetting resins is coated on one surface of the piece-shaped paper material; 4) the piece-shaped paper material coated with the thermosetting resins is wound to a pipe blank with a certain diameter through a drum; 5) the pipe blank is pressurized and heated for curing; the pressure is 10-20 MPa; the temperature is 120-150 DEG C; and the curing time is 15-40 min; and 6) the cured pipe blank is cooled at a room temperature, and is demolded to obtain a finished earthenware pipe. The preparation process of the paper pouring earthenware pipe solves the problems of high weight, high crushing cost and low production efficiency in a traditional pouring earthenware pipe.
Description
Technical field
The present invention relates to the preparation technology of papery cast earthen-ware pipe.
Technical background
The tube wall of traditional cast earthen-ware pipe is very thick, and weight is large, and fragility is large, easily peel off, need fireproof raw material fragmentation, ball milling, batching to mix during preparation make, shaping and finally burn till, complex manufacturing technology, production cycle is long, and energy consumption is high, and after disposable consumption, cost recovery is high.
Summary of the invention
The technical problem that the present invention solves provides the preparation technology of papery cast earthen-ware pipe, solves existing cast earthen-ware pipe and there is the problem that weight is large, break process cost is high and production efficiency is low.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the preparation technology of papery cast earthen-ware pipe, comprises the following steps:
1) wood fibre and binding agent are put into agitating device with the mass ratio of 5:3 and stir into even blended stock;
2) compound is put into extrusion device and extrude the sheet paper material that thickness is 1 ~ 3mm;
3) brushing one deck thermosetting resin in the one side of sheet paper material;
4) the sheet paper material of brushing heat fixation resin is rolled into the pipe embryo of certain diameter by reel;
5) pipe embryo pressurized, heated be cured, pressure is 10 ~ 20Mpa, and temperature is 120 ~ 150 DEG C, and hardening time is: 15 ~ 40min;
6) by the pipe embryo room temperature cooling after solidification, the demoulding obtains finished product earthen-ware pipe.
As preferred technical scheme, described binding agent is phosphate binders.
As preferred technical scheme, described thermosetting resin is thermosetting acrylic resin, one or more in epoxy resin, furane resins, alkyd resins, organic siliconresin and thermosetting fluoro resin are mixed.
Beneficial effect of the present invention:
1, the papery being major ingredient by lignocellulosic is poured into a mould earthen-ware pipe and is had lightweight, the advantage that the break process cost of discarded object is low;
2, wood fibre and binding agent mix, and density is more even, not easily makes earthen-ware pipe in use produce the situation of partial fracture, by being sheet paper material by compound extrusion molding, again sheet paper material is rolled into pipe embryo, fast easy to process, improve the production efficiency of earthen-ware pipe;
3, first sheet paper material is convenient to the preliminary sizing of pipe embryo by one side brushing thermosetting resin, then makes binding agent that the tube wall of whole pipe embryo is cured as one by pressurized, heated, simplifies the processing technology of earthen-ware pipe, reduces manufacturing cost.
Detailed description of the invention
The preparation technology of papery cast earthen-ware pipe of the present invention, comprises the following steps:
1) wood fibre and binding agent are put into agitating device with the mass ratio of 5:3 and stir into even blended stock;
2) compound is put into extrusion device and extrude the sheet paper material that thickness is 1 ~ 3mm;
3) brushing one deck thermosetting resin in the one side of sheet paper material;
4) the sheet paper material of brushing heat fixation resin is rolled into the pipe embryo of certain diameter by reel;
5) pipe embryo pressurized, heated be cured, pressure is 10 ~ 20Mpa, and temperature is 120 ~ 150 DEG C, and hardening time is: 15 ~ 40min;
6) by the pipe embryo room temperature cooling after solidification, the demoulding obtains finished product earthen-ware pipe.
According to the length of papery cast earthen-ware pipe actual needs, the extrusion die exit width of corresponding customization extrusion device, according to the production thickness of sheet paper material and the diameter of papery cast earthen-ware pipe actual needs, determines the cutting length of sheet paper material.
Binding agent is phosphate binders, containing the organophosphorus polymer that THPC and melamine are obtained by reacting in phosphate binders, be interspersed in phosphate binders by the molecule long-chain of organophosphorus polymer, strengthen the adhesive property of phosphate binders and ligno-cellulosic materials, improve the toughness in papery cast earthen-ware pipe internal bond region.
Containing anhydrous glucopyranose in lignocellulosic, under hot conditions, anhydrous glucopyranose pyrolysis can become levoglucosan, thus reduce lignocellulosic dehydration rate and charring rate, organophosphor high polymer is heated and discharges polyphosphoric acid, make the di in anhydrous glucopyranose, suppress the generation of levoglucosan, catalysis lignocellulosic is dehydrated into charcoal, improve dehydration rate and the charring rate of wood fibre, thus improve the resistance to elevated temperatures of papery cast earthen-ware pipe.
Thermosetting resin is thermosetting acrylic resin, one or more in epoxy resin, furane resins, alkyd resins, organic siliconresin and thermosetting fluoro resin are mixed, be convenient to the preliminary sizing of pipe embryo, then make binding agent that the tube wall of whole pipe embryo is cured as one by pressurized, heated.
