Description

Polyvinyl chloride water-proof coiled material

The invention belongs to the new design of rubber and plastic waterproof roll production method for building and equipment.

Present waterproofing materials all is directly to water to be coated on the roofing that builds a building or slit place, or adopts the apply ointment or plaster way of combination of tar felt, and its main material is a pitch.The shortcoming of above-mentioned way is, strengthened the workload of laying work, and especially in the north, summer in the winter temperature difference is big, and material is easily aging, and the life-span is short, strengthens engineering cost.

The objective of the invention is, utilize a complete set of equipment, adopt new technology, produce a kind of new waterproofing materials, it possessed waterproof is arranged, protection against the tide, anti-aging, easily characteristics such as lay.

The raw materials for production of waterproof roll of the present invention are: (1) coal tar, its amount are 1 unit, and its performance indications should meet " GB3701-83 " standard.

(2) resin: PVC Corvic, its trade mark is the XD-3 type, meet " HG-2-775-74 " middle set quota conditioned disjunction and utilize the waste and old film of polyethylene (polyvinyl chloride), or adopt pasty state blending Corvic to replace, resin content accounts for the 8-17% of coal tar.

(3) plasticizing agent: industrial o-benzoic acid dibutylester, or adopt o-phthalic acid dibutyl ester, and should meet the relevant conditional request of " HG2-465-75 " one-level or seconds, the content of plasticizing agent accounts for the 30-65% of resin.

(4) stabilizing agent: tribasic aluminum sulfate or be barium stearate, its index is: the outward appearance powder that is white in color, melting point≤130 ℃, free acid 〉=1%, total ash amount CaO9.7 ± 0.5%, fineness 0.07mm sieve aperture 200 orders 99% pass through, moisture content≤2%, the content of stabilizing agent accounts for the 0.5-3% of resin.

(5) inserts: following variously all can adopt: French chalk, flyash, quartz powder, cement slurry, zeolite, lime or red soil, its technical indicator are that fineness 80-100 mesh sieve hole is all passed through, moisture content＜3%, and inserts content accounts for the 30-80% of coal tar.

(6) base cloth: glass fabric should meet middle alkali 120B16 * 14 or middle alkali 120B12 * 16 relevant requirements, or adopts nylon cloth.

(7) contain layer again: plastic sheeting, aluminium platinum or color sand all can.

Concrete technology of the present invention and equipment needed thereby are as follows:

(1) coal tar dehydration: get a certain amount of coal tar and put into synthesis reactor and slowly heat, with temperature increase 120-140 ℃, it is that moisture content purifies that maintenance is no longer foamed until the surface.Again the coal tar that dewaters is driven into and is cooled to 40-80 ℃ in the cooling reactor.Synthesis reactor is a double wall formula structure, by the medium oil oven be heating system by pipeline to its heat supply.Cooling reactor adopts coiling sinuous coil water circulation structure in double wall formula and the still.

(2) preparation pasty mixture: will account for the resin of coal tar 8-17%, and account for the stabilizing agent of resin 0.5-3%, the plasticizing agent that accounts for resin 30-65% adds in the container in proper order, and fully mix.

(3) earlier the coal tar after the dehydrated cooled is returned in the synthesis reactor, pasty mixture and inserts are joined in the synthesis reactor in proper order again, stir and be warming up to slowly 130-140 ℃ simultaneously, kept 5-10 minute, fully plasticizing forms clay.

(4) with clay net filtration after filtration, discharge to and be cooled to 100-110 ℃ in the oil storage tank, more after filtration and put in the groove of draining the oil.The oil storage tank and the groove of draining the oil are double wall formula structure, are incubated by the medium oil furnace heating.

(5) beat the drain oil of opening groove, along with moving of base cloth, clay is spread out on the base cloth, scrapes device and spreads to even thin layer by being arranged on being coated with of two parallel guiding rulers of correspondence below the groove of draining the oil again, is bonded on the base cloth.

(6) add composite bed: composite material is plastic sheeting or aluminium platinum, place it on the film volume frame, by one group of friction roller be compounded in have the clay layer above, through one group of composite roll composite bed is compounded on the clay layer securely again, form waterproof roll; Composite bed is compounded on the clay layer through composite roll if color sand can evenly be trickled down color sand on the clay layer.

(7) cooling: cooling bath is a cooling water circulation unit, and waterproof roll cools off by the rectangle cooling bath.

(8) rolling: winder is by one group of friction roller, and the core of the card mechanism and clutch are formed, and its power comes transmission by the driven by motor sprocket wheel.Waterproof roll is wrapped on the mandrel by the friction roller group, is rotated by supporting of the core of the card mechanism and implementation, when some is arrived in the waterproof roll rolling, opens clutch and unloads finished product, adds a mandrel, and the clutch that closes works on.

(9) setting of air exhausting device: concentrate the place that the air inducing dust exhaust apparatus is being set at volatile matters such as synthesis reactor, oil storage tank, the grooves of draining the oil, purify working environment.

Waterproof roll raw material of the present invention obtains easily, and its technology is rationally feasible, and equipment needed thereby is simple, can form production line and produce continuously.Waterproof roll has excellent waterproof, moisture effect, lays easily when engineering construction, and it is strong to have adhesion strength, and plasticity is good, ageing-resistant, anti-sweltering heat, characteristics such as low temperature is soft and anticorrosion.

Fig. 1 is the schematic diagram of technological process of the present invention and production line:

Fig. 2 is a medium oil furnace heating system schematic.

Below in conjunction with accompanying drawing optimised process of the present invention and equipment needed thereby are described:

Select raw material for use: the coal tar double centner, 10 kilograms of Corvics, 5 kilograms of industrial dibutyl phthalates, 1 kilogram in tribasic aluminum sulfate, 55 kilograms in flyash, glass fabric are base cloth, plastic sheeting is a composite bed.By synthesis reactor (1), oil storage tank (3) and the groove of draining the oil (5) heat supply to the strap clamp parietal layer of oil pipe (Fig. 1 (23)) (following omission " Fig. 1 ") and oil return pipe (24), its temperature is controlled by valve by medium oil oven (Fig. 2).Earlier coal tar is rendered to slowly to be warmed up in the synthesis reactor (1) and carry out transpiration about 135 ℃, not foaming in the surface is that moisture content purifies, and is cooled in still about 60 ℃.In coal tar dehydration cooling, can prepare pasty mixture, Corvic, tribasic aluminum sulfate and industrial dibutyl phthalate (DBP) are joined in a certain container in proper order, fully mix.Pasty mixture and flyash are joined in the synthesis reactor (1) in proper order, stir simultaneously, be warming up to slowly about 120 ℃ and kept 10 minutes, fully plasticizing forms clay.Put into the filtration while putting in the oil storage tank (3) by pipe (2), leach granule foreign.By pipe (4) clay is put in the groove of draining the oil (5), lowered the temperature and remain on about 105 ℃.

Glass fabric bundle (7) is placed on the frame, pulls out glass fabric (8), and the groove of draining the oil (5) is spread out in clay on the glass fabric (8) by drain oil, is wipeed off the sticking multiple clay cloth (9) that forms on glass fabric of uniform coating again by guiding ruler (6).

Pulling out film from plastic sheeting bundle (11) is compounded in film on the clay cloth by composite roll (10), through circulating water chennel (12) cooling promptly becoming multiple film clay cloth (13), again by sturdy roller (14), (15), (16) in a down-to-earth manner, last rolling rolling (17) is a waterproof roll.

The rolling transmission is dragged by motor (18), compound, sturdy etc. by motor (19) by chain (20) transmission.

The wind-up roll group is installed on the support (21), easily waves the position air draft dust exhaust apparatus (22) has been installed at oil storage tank, drain the oil groove and other.
