Description
Technical field
This utility model relates to paper wood field, particularly to a kind of resistant to elevated temperatures release paper.
Background technology
Release paper can be described as the most again separate paper, peeling paper, Ge Laxin paper, candy wrapper, greaseproof etc. according to road processing technique thereafter and purposes, and it is the product having the antitack agent of different anti-adhesion performance at the one or both sides of the paper through pretreatment and producing.The base stock of various self adhesive material, lining paper and packaging etc. are widely used in it.Most domestic release paper manufacturer is to use common neutral sizing or raw release paper, after polyethylene or polypropylene film or plastic-coated, then through silicone coated or be directly coated with silicone oil, reaches anti-adhesion effects and stripping performance.
Domestic currently mainly using the method for single coating mould release in release paper to prepare release paper, production technology is mainly made up of base paper, parting agent layer and this three part of embossing, and its heat resisting temperature is relatively low so that other physical strengths such as resistance to elevated temperatures are relatively low.
Summary of the invention
This utility model is in order to overcome the deficiencies in the prior art, and purpose aims to provide a kind of resistant to elevated temperatures release paper, and this release paper solves the problem that current release paper heat resisting temperature is low.
In order to solve above-mentioned technical problem, the basic technical scheme that the utility model proposes is:
Concrete, this utility model provides a kind of resistant to elevated temperatures release paper, and it includes original paper layer and the alkyl ketene dimer sizing agent layer coating described original paper layer surface successively, high temperature resistant reinforcing agent unit, organic high temperature-resistant auxiliary agent unit.
Further, in described alkyl ketene dimer sizing agent layer, the volume by volume concentration of alkyl ketene dimer sizing agent is 0.86%.
Further, described high temperature resistant reinforcing agent unit includes multilamellar high temperature resistant enhancing oxidant layer.
Further, described high temperature resistant enhancing oxidant layer uses PAMC.
Further, the volume by volume concentration of described high temperature resistant enhancing oxidant layer cationic polyacrylamide is 1.5%.
Further, described organic high temperature-resistant auxiliary agent unit includes multilamellar organic high temperature-resistant auxiliary agent layer.
Further, described organic high temperature-resistant auxiliary agent layer is made up of acrylic acid modified resinoid and epoxy modified silicone resin, and according to volume by volume concentration, the ratio of acrylic acid modified resinoid and epoxy modified silicone resin is 2: 1.
The beneficial effects of the utility model are: alkyl ketene dimer sizing agent layer has good fire resistance characteristic, enable release paper moistureproof.High temperature resistant reinforcing agent unit and organic high temperature-resistant auxiliary agent unit are respectively provided with good resistance to elevated temperatures, and it can make release paper bear high temperature.
Accompanying drawing explanation
Fig. 1 provides the structural representation of a kind of resistant to elevated temperatures release paper for this utility model embodiment.
Detailed description of the invention
Below with reference to accompanying drawing 1, this utility model is described further, but protection domain of the present utility model should not limited with this.For convenience of explanation and understand that the orientation that the noun of locality that the technical solution of the utility model, following description are used all is shown with accompanying drawing is as the criterion.
Refer to Fig. 1, Fig. 1 and the structural representation of a kind of resistant to elevated temperatures release paper is provided for this utility model embodiment.As it is shown in figure 1, this release paper includes original paper layer 10 and coats the alkyl ketene dimer sizing agent layer 20 that volume by volume concentration is 0.86% on original paper layer 10 surface, high temperature resistant reinforcing agent unit 30, organic high temperature-resistant auxiliary agent unit 40 successively.Volume by volume concentration be 0.86% alkyl ketene dimer sizing agent layer 20 there is good fire resistance characteristic, it can form thin film at the fiber surface of original paper layer 10, enable release paper moistureproof.
The present embodiment original paper layer 10 is starched as raw material with bleached sulphate softwood pulp silver star slurry and Russia, is made by Wagner formula basalt beater shiny beating.
The present embodiment is high temperature resistant, and reinforcing agent unit 30 includes two-layer high temperature resistant enhancing oxidant layer 301, and certainly, high temperature resistant reinforcing agent unit 30 can also include multilamellar high temperature resistant enhancing oxidant layer 301, it is not limited to this.Further, the volume by volume concentration of the high temperature resistant enhancing oxidant layer of the present embodiment is 1.5%, and high temperature resistant enhancing oxidant layer resistance to elevated temperatures now is the strongest, and tensile strength is the highest.Enhancing oxidant layer that the present embodiment is high temperature resistant uses PAMC material, and certainly, enhancing oxidant layer 301 that this is high temperature resistant can use existing other high temperature resistant reinforcing agents on the market.
The present embodiment organic high temperature-resistant auxiliary agent unit 40 includes two-layer organic high temperature-resistant auxiliary agent layer 401, and certainly, organic high temperature-resistant auxiliary agent unit 40 can also include multilamellar organic high temperature-resistant auxiliary agent layer 401, it is not limited to this.This organic high temperature-resistant auxiliary agent layer 401 is made up of acrylic acid modified resinoid and epoxy modified silicone resin, according to volume by volume concentration, the ratio of acrylic acid modified resinoid and epoxy modified silicone resin is 2: 1, and now, the resistance to elevated temperatures of organic high temperature-resistant auxiliary agent layer 401 is optimum.Organic high temperature-resistant auxiliary agent layer 401 can use existing organic high temperature-resistant auxiliary agent on the market.
In sum, high temperature resistant reinforcing agent unit 30 and organic high temperature-resistant auxiliary agent unit 40 are respectively provided with good resistance to elevated temperatures, and it can make release paper bear high temperature.After testing, the present embodiment release paper can bear the high temperature of 240 degree.
The announcement of book and teaching according to the above description, above-mentioned embodiment can also be changed and revise by this utility model those skilled in the art.Therefore, this utility model is not limited to detailed description of the invention disclosed and described above, should also be as falling in scope of the claims of the present utility model to modifications and changes more of the present utility model.Although additionally, employ some specific terms in this specification, but these terms are merely for convenience of description, this utility model is not constituted any restriction.
