Description
Technical field
A kind of preparation method of composite decoration film basement membrane of the present invention.It can be with the base material such as timber, plastic plate, aluminium sheet, iron plate
It is compound to make multipurpose ornament materials, it is widely used in household electrical appliance, sound equipment incrustation, interior decoration, aircraft, steamer, fire
The interior trim of car.
Background technology
Decorating film is widely used to outdoor aluminum alloy doors and windows in countries such as Germany, Japan, Korea, as laminating decoration
Film, decorating film introduces China since 21 century.The conventionally manufactured decorating film of China is made up of PVC material, in PVC molecular structures
There is more unstable active Cl-Double bond structure is easily formed, makes polyvinyl chloride resin weatherability be deteriorated, held during use out of doors
Easily destroyed by sunlight middle-ultraviolet lamp and cause the metachromatism such as polyvinyl chloride resin jaundice, rubescent.ASA material main components are ASA trees
Fat, the terpolymer being made up of acrylonitrile (A), styrene (S) and acrylate (A), without double bond etc. in its molecular structure
Unstable group, molecular structure stabilized, with excellent weather resistance, while the material has good mechanical property.It is domestic
Existing manufacturer production goes out ASA/PVC composite materials, but the ripe production technology of the also non-ASA/PVC composite membranes of domestic manufacturer.Because
There are several technological difficulties in its production technology：PVC and ASA have difference of flowability, and flow velocity is asynchronous；Material is in co-extrusion connector
Interior flowing is not smooth, easily blocking, difficult control of temperature during co-extrusion；ASA co-extrusions material is soft during extrusion, is also easy to produce cut.
The content of the invention
It is an object of the invention to provide a kind of good weatherability, intensity height, the preparation of fire-retardant scratch resistant composite decoration film basement membrane
Method.
The present invention the adopted technical scheme that solves the above problems is：A kind of preparation method of composite decoration film basement membrane, institute
The method of stating comprises the steps：
Step one：ASA and PVC plastic powder are each separately added into into different high-speed mixers, are added in ASA a certain proportion of
Processing aid is modified.A certain proportion of heat stabilizer, processing modified adjuvant, impact modifying agent is added to be modified in PVC.
Step 2：Powder morphology is set to be changed into plastic pellet form by Granulation Equipments respectively in ASA and PVC plastic powder.
Step 3：ASA and PVC redesign being total to for co-extrusion connector after being respectively dried according to specific ratio, employing
Extruder extrudes composite decoration film basement membrane.
Step 4：Unlatching adds lustre to equipment, and to extrusion composite decoration film membrane surface out the process that adds lustre to is carried out.
Step 5：Composite decoration film basement membrane cooling and shaping is waited, then winding, packaging.
The processing aid added in ASA in the step one is magnesium stearate（MgSt）.And calculate the ratio of addition in mass ratio
Example is the 1% of ASA.The heat stabilizer added in PVC is hydrogen donor or the tertiary amines electronq donors such as secondary arylamine, and by quality
Than calculating its ratio for the 2% of PVC.The processing modified adjuvant added in PVC is ACR (methyl methacrylate and acrylate benzene second
The copolymer of the monomers such as alkene), and its ratio is calculated in mass ratio for the 2% of PVC.The impact modifying agent added in PVC is MBS, and is pressed
Mass ratio calculates 1.5% that its ratio is PVC.
The specific usage ratios of ASA and PVC are 1 during co-extrusion film forming in the step 3:2.
The co-extrusion connector redesigned in the step 3 compares common co-extrusion connector runner inside at polishing
Reason makes its surface smooth, reduces flow resistance；Heater is increased on co-extrusion connector, prevents material from cooling down, it is ensured that its
Flowing is smooth, prevents blocking；Heater when can ensure that material stream to extrusion simultaneously there is suitable temperature to be combined
Extrusion, it is ensured that the composite decoration film basement membrane of coextrusion has good combined strength bination.
Described step four adds lustre to step the step of increase for this production technology.The equipment that adds lustre to is assemblied in after extrusion, just
The composite decoration film basement membrane top of extrusion.For processing the membrane surface extruded, the defects such as the cut on surface are eliminated, protected
Demonstrate,prove its quality.The equipment that adds lustre to purges two parts and constitutes by electric-heating-wire-heating and Hot-blast Heating, and electrical heating wire is highly to be placed on film
Square 10-15 centimeters, blowing hot wind is in electrical heating wire rear 80-100 centimeters, and height is film top 20-25 centimeters.Two
Divide to cooperate and carry out the process that adds lustre to composite decoration film membrane surface.
Compared with prior art, it is an advantage of the current invention that：
The composite decoration film basement membrane has good weatherability, and intensity is high, and surface is smooth, and the advantages of fire-retardant scratch resistant, surface is again through print
Composite decoration film of the rich color suitable for materials such as aluminium alloys can be just made after brush process.
