Description
Technical field
The present invention relates to a kind of preparation methods of high-temperature stable release paper, belong to release paper field of material technology.
Background technology
Leather production release paper belongs to one kind of coating separate paper, is the cruel synthetic leather of polyurethane referred to as leather and polychlorostyrene
The carrier and temporary mold of vinyl leathercloth's referred to as leather manufacture.Early stage with leather production is produced using stainless steel band method, i.e.,
Paste resin is coated on stainless steel band, after drying and moulding, then through cotton gin shuts out certain decorative pattern.It was given birth to later with release paper method
Production substitutes stainless steel band with release paper.Since release paper surface is first rolled into certain decorative pattern, surface layer has superperformance
Release layer is directly repeatedly coated in release layer surface with paste resin, and foamed process, drying, solidification crosslinking sizing,
Then release paper stripping being can be made into smooth surface or have the foam plastic of the dermatine in ridge design face or reflecting feel
Material products.Release paper method is more reasonable than the technique of the production of stainless steel band method and leather, equipment is simple, investment economy is particularly conducive to
Foaming, make made of synthetic leather density is small, good hand touch.One third can be saved to the various industrial chemicals of half, and energy
Be made density it is lower and leather, improve product quality.In addition the fabric optimum application to certain fabrics and to strain sensitive, energy
Prepare soft, good hand touch plastic film layer.
Release paper, production technology master is made in the domestic main method using the single coating mould release in release base paper at present
It by base paper, parting agent layer and to be embossed this three parts and forms, heat resisting temperature is relatively low so that other physical strengths such as high temperature resistance
It is relatively low；And the heat resisting temperature of external high temperature resistant release paper can reach 265 DEG C, and still there is preferable heat-resisting quantity
Energy.Domestic required high temperature resistant release paper is caused all to rely on import at present.Therefore the research and development tool of this high temperature resistant release paper
There are very high market value and social effect.
Invention content
The technical problems to be solved by the invention：For the problem that existing release paper material high temperature resistance is poor, provide
A kind of preparation method of high-temperature stable release paper.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
（1）Peach gum and vacuum freeze drying are taken, grinds and is sieved, obtain peach gum powder and count in parts by weight, weigh respectively
45~50 parts of deionized waters, 6~8 parts of methanol, 3~5 parts of emulsifier op-10s and 10~15 parts of peach gum powder are stirred, homogeneous
Processing, ultrasonic disperse must disperse modification liquid；
（2）It counts in parts by weight again, weighs 45~50 parts of deionized waters, 3~5 parts of zirconium oxychlorides, 6~8 parts of boraxs and vinegar respectively
Acid solution is placed in beaker, is stirred to obtain mixed liquor, adjusts pH to 8.5, and heating water bath obtains matrix liquid；
（3）It counts in parts by weight, weighs 45~50 parts of deionized waters, 3~5 parts of potassium chloride, 1~2 part of formaldehyde, 0.5~1.0 respectively
Part sodium hydroxide, 0.5~1.0 part of hexamethylenetetramine, 10~15 parts of matrix liquid and 10~15 parts of disperse modified liquid are placed in three mouthfuls
In flask, heating water bath, standing is cooled to room temperature to obtain coating modification liquid；
（4）Bleached softwood wood wood pulp is taken to be placed in defibrination process in PFI fiberizers, in mass ratio 1:10, by 200 mesh hydroxy-apatites
Stone powder is added in wood pulp slurry, is stirred and copy paper is handled and dried, obtain dry paper；
（5）Dry paper is placed on coating machine, processing is coated with coating modification liquid to modified page, it is dry after the completion of coating
Dry 2~3min, the high-temperature stable release paper can be prepared by then standing to be cooled to room temperature.
Step（4）The wood pulp slurry is the wood pulp slurry of 35 ° of SR of beating degree.
Step（5）Each coating thickness is 0.1mm to the coating process in order to control, often coating once places it in 95~
Dry 45~60s, is coated with 3 times repeatedly at 100 DEG C.
Compared with other methods, advantageous effects are the present invention：
Technical solution of the present invention uses peach gum for coating liquid main body, is effectively coated to paper fibrous material surface, while
After coating modification, colloid prevents organic material from going deep into inside paper fibre, is inhaled by this inorganic filling material of hydroxyapatite
Heat is received, while coating organic high temperature-resistant auxiliary agent in modification liquid and reacting under the action of high temperature, degradation absorbs fiber surface
Temperature, prevent fiber occur thermal degradation, protect fiber, by organic material and inorganic filler mixing and to paper fibre carry out
Fully cladding, this layer film is by when page is heated, inorganic high-temperature resistant auxiliary agent absorbs heat, the group in organic high temperature-resistant auxiliary agent
Heat is absorbed etc. decomposing, reduces the temperature of fiber surface, prevents fiber from thermal degradation occurs to effectively improve system of the present invention
Standby release paper has excellent high temperature resistance.
