Circular screen copy-jeting wax and making method thereof

Abstract

A wax for making screen plate by cylinder spraying is prepared from olefine oxide (10-20 pts. wt.), high-molecular hydrocarbon with 82.5 deg.C of melting point (40-55 pts.wt.), high-molecular hydrocarbon with 59-65 deg.C of melting point (20-30 pts.wt.), rosin pentaerythritol ester as adhesive (2-5 pts.wt.) and black pigment (3-5 pts.wt.). Its advantages are not blocking nozzle, clear mesh and lifelike pattern.

Description

Technical field:

[0001] The present invention relates to a draft spray wax and its manufacturing method, more particularly to a rotary screen draft spraying measure for computer rotary screen plate making and its manufacturing method. Background technique:

[0002] In the prior art, the production by the traditional method must first be made into a black and white draft to achieve the purpose of color separation and plate making. Its biggest disadvantage is that it is easy to produce seams at the stitching of unit patterns, the accuracy of plate making is not high, and it is difficult to print fine patterns. So far, no invention patent report related to draft wax has been found after searching for novelty. Invention content:

[0003] The purpose of the present invention is to overcome the defect that the prior art exists, to provide a kind of spray nozzle that does not block up in the process of spraying wax, and the minimum spray point is 30 picoliters (30 * 10 -12 l), ...

Examples

example 1

[0045] Weigh raw materials according to the following proportions:

[0046] 1.5 kg of oxyalkylene polymer,

[0047] 5 kg of high molecular hydrocarbons with a melting point of 82.5°C,

[0048] 3 kg of high molecular hydrocarbons with a melting point of 59-65°C,

[0049] Rosin pentaerythritol ester binder 0.2 kg,

[0050] Black pigment 0.3 kg.

[0051] Make rotary screen spray wax as follows:

[0052] A. First, heat the rosin pentaerythritol ester to 120° C. to melt into a viscous body, and gradually add 0.4 kg of organic solvent ethanol dropwise, and stir while adding, until it is evenly diluted, and the rosin pentaerythritol ester adhesive is made;

[0053] B. Mix the oxyalkylene polymer and the black pigment, put it into the reaction kettle and raise the temperature to 150°C while stirring, and keep the temperature constant for 2-3 hours;

[0054] C. Put in high molecular hydrocarbons with a melting point of 82.5°C and high molecular hydrocarbons with a melting point of...

[0067] Weigh raw materials according to the following proportions:

[0068] Oxygenated polymer 2 kg

[0069] High molecular hydrocarbon with a melting point of 82.5°C 5 kg

[0070] Melting point 59-65 ℃ polymer hydrocarbon 2 kg

[0071] Rosin pentaerythritol ester binder 0.5 kg

[0072] Black pigment 0.3 kg.

[0073] The method is the same as Example 1. The wax sprayed on the rotary screen produced by the above-mentioned manufacturing method has no precipitation phenomenon, is easy to filter, does not block the nozzle, and has a good net-making effect by spraying the wax.
