Abstract

The invention discloses a method for manufacturing base paper for electronic industry, which comprises the following steps: firstly, preparing mixed resin for soaking cotton white paper; secondly, drying the cotton white paper after soaking the coiled cotton white paper in the mixed resin at a speed of between 60 and 70 meters/minute; thirdly, stacking the cotton white paper together; coating a copper foil layer on the stacked paper; pressurizing and heating the paper coated with the copper foil layer for 130 to 140 minutes to obtain board base paper; cutting the board base paper according to a set size; and packaging the cut board base paper into the base paper after the board base paper is inspected to be qualified through quality inspection. The method has the advantages that as no waste is generated in the whole production process, the method is clean and environment-friendly; as the method adopts 100 percent bleached sulfite eucalyptus pulp as the cotton white paper for producing the raw material, the method can improve optical performance, green strength, penetrability and hygroscopicity of the base paper and can also improve the production speed and product quality, thereby reducing production cost.

Description

A kind of manufacture method of base paper for electronic industry

Technical field

The present invention relates to a kind of manufacture method of paper, is a kind of manufacture method of base paper for electronic industry specifically.

Background technology

Paper be for write, write down, print, multi-purpose sheet-like fiber goods such as drawing or packing.Be divided into hand-made paper and machine-made paper by the mode of production, hand-made paper is based on manual operations, and shortcoming is that output is little; Machine-made paper is meant the general name of the paper of producing in the mechanization mode, as printing paper, wrapping paper etc.Be divided into by purposes: newsprint, printing paper, writing paper, wrapping paper, technical paper, living-hygienic paper, base paper, cardboard and converted paper etc.

The copper-clad laminate body paper is to produce the basic material of printed substrate with full paper substrate copper-clad laminate, it is the higher extraordinary industrial paper of a kind of production difficulty, but at present in the manufacture process of copper-clad laminate body paper, the high energy of the speed that cotton white paper soaks through hybrid resin reaches 35 meters/minute, speed of production is slow, can not satisfy the demand of existing market, and employed raw material cotton white paper is easily damaged, wet strength is low, poor permeability, impregnation speed are slow, thereby make that the original paper quality of producing is poor, further improved production cost.

Summary of the invention

Goal of the invention: the objective of the invention is in order to overcome the deficiencies in the prior art the manufacture method of the base paper for electronic industry that provide a kind of clean environmental protection, can increase work efficiency, improves the quality of products.

Technical scheme: in order to solve the problems of the technologies described above, the manufacture method of a kind of base paper for electronic industry of the present invention, the concrete steps of this method are as follows:

1) formulated phenolic resin: add in the reactor with phenol, tung oil, to benzene methanesulfonic acid and to stir, be heated to 78～82 ℃ with 25～30 minutes, then 78～82 ℃ of reactions 2 hours, tested viscosity reaches 40-45 pool back and adds triethanolamine generation tung oil phenol dimer, add formaldehyde, triethylamine, ammoniacal liquor then 90～100 ℃ of reactions 3～4 hours, begin to vacuumize to dewater being made into the phenolic resins of solid content 50%～55% to resin transparent input methyl alcohol then;

2) cotton white paper with rolling passes through the phenolic resins immersion treatment with 60～70 meters/minute speed;

3) cotton white paper after the immersion treatment is dried;

4) quires after will drying is put together;

5) be covered with copper foil layer above the paper that in step 4), is stacked together;

6) paper that will be covered with copper foil layer is that 150～160 ℃, pressure are 110～120Kg/m in temperature ²Condition under heating and pressurizing handle after 130～140 minutes and obtain plate base paper;

7) plate base paper is cut according to setting size;

8) the plate base paper after will cutting carries out being packaged into described body paper after the quality passed examination.

Each raw materials in part by weight is respectively in the step 1): 1 part of tung oil, 1～6 part of phenol, to 0.005～0.0015 part of benzene methanesulfonic acid, 0.006～0.0095 part of triethanolamine, 2～5 parts in formaldehyde, 0.01～0.04 part of triethylamine, 0.01～0.02 part of ammoniacal liquor, 2～6 parts of methyl alcohol.

The reaction mechanism of formulated phenolic resin is in the step 1): the first step by tung oil, phenol under the effect of acidic catalyst, the two keys of tung oil are opened by phenol addition reaction are taken place with it, form the dimer of tung oil phenol, the size of molecular weight is done with control by triethanolamine; Second step added formaldehyde and base catalyst in the tung oil phenol dimer of first step alkylated reaction generation, under the effect of base catalyst substitution reaction takes place by the phenyl ring on the phenol, form hydroxymethyl chemistry structure, crosslinked generation polycondensation reaction by it obtains end product again, adds the suitable solid content of certain solvent furnishing.

The phenolic resins solid content that is adopted among the present invention can better adhere to phenolic resins on the cotton white paper 50%～55%, and is not only economical and practical, and can be fire-retardant.

It is that raw material is made that described cotton white paper adopts 100% bleaching sulphite eucalyptus pulp.Because it is raw material that the present invention has adopted with 100% bleaching sulphite eucalyptus pulp, make this cotton white paper have wet strength height, impregnation constantly, the characteristics of fast, the good water absorption of good penetrability, impregnation speed, therefore can make the smooth exquisiteness of product appearance, and in manufacture process, make this cotton white paper with 60～70 meters/minute speed cracky by hybrid resin and not, speed of production is obviously improved for more existing the highest 35 meters/minute, and can improve the quality of product, thereby reduce production costs.

In step 4), cotton white paper is built up eight layers.The number of plies that cotton white paper stacks can be determined as required.

Beneficial effect: compared with prior art, advantage of the present invention is because whole process of production emits no waste water, so clean environmental protection; Owing to adopt the cotton white paper of 100% bleaching sulphite eucalyptus pulp as raw material production, can improve optical property, wet strength, permeability, the water imbibition of body paper, can also improve speed of production and product quality, thereby can reduce production costs; Employing phenolic resins is soak, and is not only economical and practical, and can be fire-retardant.
