CN103773630A - Novel quick drying screen washing agent - Google Patents

Abstract

The invention discloses a novel quick drying screen washing agent, which is prepared from the following raw materials in parts by weight: 60-80 parts of isophorone, 3-7 parts of butyl acetate, 8-15 parts of ethylene glycol monobutyl ether, and 7-16 parts of dimethylbenzene. By adopting the novel quick drying screen washing agent, the cost of the screen washing agent can be effectively reduced; the added butyl acetate ingredient has fresh scents of fruits, so that a pungent smell of isophorone can be effectively inhibited, and the damage to a human body is reduced; ethylene glycol monobutyl ether ingredient is added, so that the screening washing agent is more even and more stable in performance. In addition, ethylene glycol monobutyl ether has the characteristic of being quick in volatilization, so that the washed screen printing plate is quicker to dry, the drying time of the screen printing plate is saved, and reuse of the screen printing plate is facilitated.

Description

A kind of novel quick-dry type net washing water

Technical field

The present invention relates to half tone in pcb board production process and return the material of washing, particularly relate to a kind of novel quick-dry type net washing water.

Background technology

In printed circuit board (pcb) processing procedure, the quality of half tone quality is directly connected to the quality of printed circuit board quality.Although liquid exposure image shifting process just progressively replaces traditional wire mark technique, but from current manufacturer, analyze from operating procedure and production cost aspect, traditional wire mark technique is difficult to be eliminated within a certain period of time, and this is ripe a, production technique cheaply after all.Therefore, the application of half tone or commonplace.

In PCB production process, have anti-welding and two operations of character all will use half tone, the circuit that wet film technique is walked by some company certainly also can be used half tone.Half tone is as a kind of important tool of producing in PCB, and it has the advantages that to recycle, recycle and must half tone be returned and be washed, and half tone to return the main material of washing be exactly net washing water.

Traditional net washing water all adopts isophorone liquid to clean half tone, isophorone is the colourless volatile liquid that has characteristic odor (camphor/mint flavored) to yellow, belong to lower toxicity material, strong to mucous membrane, skin irritation, so clean with it, half tone taste is large, pungency is strong, in addition, the half tone of washing is not easy to do.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, provide that a kind of cost is low, the novel quick-dry type net washing water of stable performance, the irritating smell that it can effectively suppress isophorone, reduces the harm to human body; Can make dry faster of the half tone washed, save half tone time of drying.

The object of the invention is to be achieved through the following technical solutions: a kind of novel quick-dry type net washing water, it is made up of the raw material of following weight part:

Isophorone: 60 ~ 80 parts;

N-BUTYL ACETATE: 3 ~ 7 parts;

Ethylene glycol monobutyl ether: 8 ~ 15 parts;

Dimethylbenzene: 7 ~ 16 parts.

As preferably, this novel quick-dry type net washing water is made up of the raw material of following weight part:

Isophorone: 70 ~ 75 parts;

N-BUTYL ACETATE: 4 ~ 6 parts;

Ethylene glycol monobutyl ether: 8 ~ 12 parts;

Dimethylbenzene: 10 ~ 14 parts.

The invention has the beneficial effects as follows:

(1) can effectively reduce the cost of net washing water, the net washing water of making by the weight part of specifying by these raw materials of isophorone, N-BUTYL ACETATE, ethylene glycol monobutyl ether and dimethylbenzene, with respect to traditional whole net washing waters made from isophorone, can reduce by 10% left and right on cost;

(2) add N-BUTYL ACETATE composition, because N-BUTYL ACETATE has fruit fragrant, can effectively suppress the irritating smell of isophorone, reduce the harm to human body;

(3) add ethylene glycol monobutyl ether composition, make net washing water more even, performance is more stable, and in addition, due to ethylene glycol monobutyl ether, to have volatility fast, makes dry faster of the half tone washed, saves time, and is convenient to reusing of half tone.
