Abstract
The preparation process of nano antistatic protecting overlaid plate includes the following steps: mixing melamine and polyformaldehyde to compound glue pre-polymer; preparing nano zinc oxide material via sol-gel process via controlling calcining temperature and adding polyvinyl alcohol or gelatin to control granularity; surface treating nano zinc oxide material with silane and similar cross-linking agent; dispersing nano zinc oxide material via ultrasonic vibration and stirring to the pre-polymer; soaking paper for making the decorating plate in the pre-polymer with nano material, air drying, stoving and pressing in a plate press into the nano modified decorating overlaid plate. The nano modified decorating overlaid plate has resistivity of about 10 to the -7 power ohm and good antistatic protecting function, and may be used in decoration of computer room, furniture, vehicle, etc.
Description
Technical field under in the of one
The present invention relates to a kind of nano protecting preparation of plates method, particularly a kind of preparation method of nano-anti static protection thick china.
Two background technologies
Because most of plastics and other macromolecular material product all have good insulation performance and water tolerance, as carbamide resinous materials decorative sheet excellent property, heat-resisting, wear-resisting, anti-pollutions etc. better, it is a kind of ideal finishing material, be widely used in aircraft, vehicle, boats and ships, furniture etc., its surface resistivity is generally (10
12-10
14) between the Ω, when existing, these good performances also brought static hazard for plastics from the negative.When plastics produce static because of friction,, add that suction is poor because their resistivity is very high, be easy to form static and be difficult for disappearance, static is constantly assembled increase, makes plastics charged, this electrostatic interaction makes surface of plastic products adsorb dust easily, has influenced use properties.The harm that is brought by static not only makes precision instrument such as computer quit work, and can initiation fire and the hidden danger of explosion hazard.
In order to eliminate static hidden danger, enlarge the range of application of carbamide resinous materials decorative sheet, eliminate static hazard, for just carrying out modification, the surface resistivity of this series products is stabilized in certain scope to existing material.
Three summary of the invention
The object of the present invention is to provide a kind of surface resistivity that reduces protection with thick china, eliminate electrostatic accident, be applicable to the preparation method of the nano-anti static protection thick china that machine room, furniture, vehicle etc. are decorated.
The technical solution that realizes the object of the invention is: a kind of preparation method of nano-anti static protection thick china, it is characterized in that: trimeric cyanamide and formaldehyde resin are hybridly prepared into pre-assemble adhesive, prepare nano zinc oxide material with sol-gel method, by control calcining temperature and adding polyvinyl alcohol (PEG) or gelatin control nano particle diameter, with the Instrument measuring nano material the grain through size, crystal formation, brilliant looks, the fluorescent property of nano material and the nano material dispersion state in the protection thick china, with the type siloxane coupling agent nano zinc oxide material is carried out surface treatment, through sonic oscillation and stirring nano zinc oxide material is distributed in the carbamide resinoid pre-assemble adhesive equably, form nano material-antistatic pre-assemble adhesive of carbamide resinoid, decorative sheet is fully flooded in nano material-carbamide resinoid pre-assemble adhesive with paper, dry, 105-110 ℃ of oven dry down, in trigger squeeze, be pressed into the nano modification decoration veneer.
The present invention compared with prior art, its remarkable advantage is: through the surface resistivity of the carbamide resinous materials decoration veneer of nano modification by original 10
12Drop to 10 about Ω
7About Ω, reduced the surface resistivity of protection, can eliminate electrostatic accident, be applicable to decorations such as machine room, furniture, vehicle with thick china.
Four description of drawings
Accompanying drawing is preparation method's schematic flow sheet of nano-anti static protection thick china of the present invention.
Five embodiments
Below in conjunction with accompanying drawing the present invention is further described.
In conjunction with the accompanying drawings, the preparation method of nano-anti static protection thick china of the present invention the steps include:
1, trimeric cyanamide: formaldehyde=1: 3 (mol ratio) is mixed with pre-assemble adhesive;
2, zinc nitrate is added in the stearic acid fusing, adopt sol-gel method to prepare nano zinc oxide material, control the nano particle grain through about 40 nanometers by control calcining temperature and adding polyvinyl alcohol (PEG) or gelatin;
3, with the type siloxane coupling agent nano material is carried out surface treatment;
4, the surface-treated nano material is joined by a certain percentage in the carbamide resinoid pre-assemble adhesive, standby through sonic oscillation and stirring;
5, decoration veneer is cut into the certain size size with paper, two this class experiment paper are prepared in each test, and numbering;
6, will test paper and immerse in nano material/carbamide class pre-assemble adhesive, fully dipping takes out then, is clipped on the yoke, scrapes off the unnecessary glue in paper surface with glass stick;
7, the experiment paper of impregnation is put into drying in oven, temperature is controlled in (105-110) ℃ scope;
8, the experiment paper that will dry takes out in baking oven, repeats 6,7 steps more once;
9, nano material/carbamide resinoid pre-assemble adhesive experiment paper is put into trigger squeeze and is pressed into the nano modification decoration veneer;
10, nano material/carbamide resinous materials decoration veneer is carried out the surface resistivity test.
