Description
Technical field
The present invention relates to polyurethane plate field more particularly to a kind of preparation sides of shell sound-insulating polyurethane plate
Method.
Background technique
Shell is an important species in marine product, delicious flavour and very popular, but shell seafood
The edible generation for but resulting in a large amount of waste shells.If be allowed under accumulation or landfill, large amount of land resources will be occupied simultaneously
Calcium base physical waste is caused, and this kind of shell is generated often through kitchen garbage form, so that mosquitos and flies breeds, seriously pollutes ring
Border forms environmental hazard.Therefore, the recycling and reusing of waste shell just becomes a urgent problem to be solved.But current returns
Receipts technology but have the disadvantage in that first is that due to the waste shell in current kitchen often be used as kitchen garbage to be handled,
So that waste shell in kitchen need after collecting layer by layer can garbage transfer station to the end, collect process
Time-consuming long and sort process is also relatively difficult；Second is that the waste shell in kitchen is during conventional acquisition, often with kitchen rubbish
Rubbish mixes, and causes shell smelly spoiled and the shell for breeding various bacteriums, therefore sorting out generally requires to again pass by
Cleaning and disinfection and etc. it is rear just can apply to subsequent recovery recycle process；Third is that if be scratched accidentally in sort process
It is also possible to sorting personnel is caused to infect.
The problem to be solved in the present invention is that the waste shell in kitchen how to be avoided to occur with kitchen garbage formal layout
Sorting is difficult and the fouling that occurs during collection and the problem of breed bacterium, and make full use of waste shell preparation every
Sound heat insulating polyurethane plate.
Therefore, those skilled in the art is dedicated to developing a kind of preparation side of shell sound-insulating polyurethane plate
Method.
Summary of the invention
In view of the above drawbacks of the prior art, useless in kitchen the technical problem to be solved by the present invention is to how to avoid
It abandons the shell sorting difficulty occurred with kitchen garbage formal layout and the fouling occurred during collection and breeds bacterium
The problem of, and waste shell is made full use of to prepare sound-insulating polyurethane plate.
To achieve the above object, the present invention provides a kind of preparation method of shell sound-insulating polyurethane plate,

Parallel four straight lines of long side on, the spacing of the shell on every straight line is identical；
(3) the first raw material of polyurethane and the second raw material of polyurethane ratio of 100:100-110 in mass ratio are sent out in low pressure
The middle section for being placed with the aluminium alloy plate groove of the shell is expressed into after mixing in bubble machine, then masking foil is covered on described
On aluminium alloy plate groove, the aluminium alloy plate groove is along the belt movement direction sliding of belt conveyor and by described in two layers
The extruding of belt.
Further, it is small less than 4cm, length to be less than 2cm, width for height after the shell in the step (1) is laid flat
In 8cm.
Further, a wherein long side for aluminium alloy plate groove described in distance is nearest in the step (2) one
The distance of straight line described in item is not less than 19cm and is not more than 23cm, and the distance between described straight line is 6cm.
Further, the spacing of the shell on every straight line in the step (2) is 15-20cm.
Further, the shell on the adjacent straight line in the step (2) mutually staggers placement.
Further, modes of emplacement of the shell in the step (3) on the aluminium alloy plate groove is convex surface
Downward, concave surface upward, it is arc-shaped towards the belt movement direction.
Further, the mass ratio of the ingredient of the first raw material of the polyurethane in the step (3) is polyether polyol

Specific embodiment
Multiple preferred embodiments of the invention are introduced below with reference to Figure of description, keep its technology contents more clear and just
In understanding.The present invention can be emerged from by many various forms of embodiments, and protection scope of the present invention not only limits
The embodiment that Yu Wenzhong is mentioned.
Steps are as follows for first embodiment:
1, the cleaning of shell
120 minutes flower mussel shells are put into tap water after edible after stirring fry in oil, and 90 DEG C of hot water is put into after rinsing 1 time
In, it impregnates 30 minutes, pulls out, be put into normal-temperature water, cleaning agent is added and cleans 1 time, is rinsed with tap water, is put into 80-90 DEG C of drum
It dries within 30 minutes in wind baking oven；Shell that will be broken in washing process removes, and selects after laying flat highly less than 2 centimetres, width
Degree is less than 4 centimetres, shell of the length less than 8 centimetres.
2, placement of the shell on polyurethane plate production line
It is 3 centimetres that aluminum alloy plate materials, which first pass through folding brake and form both sides height, the aluminium alloy that intermediate width is 60 centimetres
Plate groove, shell are placed with four lines, this four lines respectively from left side 19-23 centimeters, 25-29 centimeters, 31-35 and
37-41 centimeters.It is divided into 15-20 centimetres between two shells on every straight line, it is crisscross alternate between every line, such as Fig. 1 institute
Show.The modes of emplacement of shell be convex surface downward, upward, root is arc-shaped preceding rear, as shown in Figure 2 for concave surface.
3, the production of the polyurethane plate of shell enhancing
Polyurethane A material and B material are expressed into after mixing in low-pressure blowing machine according to the ratio of mass ratio 100:108 and are covered with shellfish
The central part of the aluminium alloy plate of shell, aluminium alloy plate is covered on aluminium alloy plate with belt forward slip, masking foil, through temperature
To ultimately form closed polyurethane plate after 45 DEG C of two layers of belt squeeze.
The mass ratio of the ingredient of the polyurethane A material are as follows: polyether polyol 4110: polyether polyol 7050: water: N, N- bis-
Methyl cyclohexylamine (PC-8): potassium acetate: a fluorine dichloroethanes (HCFC-141B): polysiloxanes-oxyalkylene block copolymer:
Diethyl ethylphosphate (DEEP)=70:30:1:1.2:3:14:5:20；
The polyurethane B material is polyphenyl polymethylene polyisocyanates, NCO content 30.5%；
Polyurethane plate finished product is as shown in Figure 3 and Figure 4.It is detected, the thermally conductive of the polyurethane plate after spending mussel shell is added
Coefficient is that 0.024 (w/m.k) is slightly improved, but sound-absorbing compared with the 0.023 of polyurethane plate of shell (w/m.k) is not added
Coefficient reaches 92%, has large increase than the 80% of polyurethane plate of shell is not added.In addition, in combustion, adding
The polyurethane plate for entering shell reduces 60% than the smoke that the polyurethane plate of shell generates is not added.
It is identical with first embodiment in addition to following in all steps of second embodiment:
Using cooking, 180 minutes mussel shells are put into tap water after edible, and 90 DEG C of hot water is put into after rinsing 1 time
It is middle to impregnate 40 minutes, then pull out.
It is detected, the thermal coefficient of the polyurethane plate after flower mussel shell is added is 0.0235 (w/m.k), and shellfish is not added
0.023 (w/m.k) of the polyurethane plate of shell is compared, and is slightly improved, but sound-absorption coefficient reaches 90%, than the poly- of shell is not added
The 80% of urethane plate has large increase.In addition, in combustion, shell is not added for the polyurethane plate ratio that shell is added
Polyurethane plate generate smoke reduce 65%.
