Description
Technical field
The invention belongs to release paper preparation fields, and in particular to a kind of uvioresistant release paper and preparation method thereof.
Background technique
Release paper is also known as barrier paper, separate paper, silicone oil paper.It is that one kind prevents prepreg adhesion, and can protect prepreg
Not contaminated separate paper, the surface for being mainly covered in adhesive tape are used to protect the gluing oxidant layer of tape surface.Traditional release paper
It is made of body paper, separation layer and adherent layer.Its preparation process is one layer of interleaving agent of base stock surface lamination (isolation in release paper
Agent is mainly polyethylene), one layer of antitack agent (antitack agent is mainly silicone oil) then, which is coated with, on the surface of leaching membrane layer obtains release paper.
Release paper is made of the paper for being coated with preventing viscosity substance, model will according to material, thickness, elongation, single two-sided difference and distinguish.
Release paper is divided by color: single silicon white release paper refers to it is plain paper on one side, is silicone oil on one side, more common.Single silicon is yellow
Color release paper, referring to two faces all is the release paper of yellow.Classify by grammes per square metre: gram/m being differed from 35 grams/m to 250.It presses
Silicone oil classification: by whether there is or not add silicone oil that can be divided into silicone oil paper and leaching membrane paper.By single two-sided classification: double silicon list envelopes refer to it is silicone oil on one side,
There was only lamination on one side, this kind can increase to clean degree.Double silicon refer to that two sides is all silicone oil.Single silicon.Leaching membrane paper, alternatively referred to as
White modeling paper.
Release paper should meet: can cling prepreg, but be easy to separate the two；It is not chemically reacted with resin system
Or pollution resin system；When ambient temperature and humidity changes, the length of release paper, width should all be remained unchanged, in order to avoid cause
Release paper wrinkles and makes prepreg fold；There should be enough compactness, can prevent moisture from entering in prepreg by it；It is release
Its elongation should be consistent with fiber after paper is towed, to prevent prepreg from drawing during the preparation process since drawing-off is asynchronous
Play deformation or distortion；Its thickness, mass area ratio are not easy accurately to control.
With the continuous progress of science and technology, release paper using more and more extensive, especially in food, chemical industry, electronics etc.
Packaging field, but current release paper is due to lacking anti-ultraviolet function is easy by ultraviolet damage to aging, broken
Damage influences whether that the product after being packed is damaged, therefore in order to expand the application field of release paper, a kind of energy uvioresistant
The release paper of line urgently occurs.
