Embodiment 1

[0019] 0.1% by weight of potassium lauryl ether phosphate (Guangzhou Xinlin Chemical Co., Ltd., brand XL-1) and 0.1% by weight of coconut acid diethanolamide are mixed with water to form a mixture, added to boiling water, stirred to make it dissolve, and then Add 6.0% by weight of sodium hydroxide, 1.5% by weight of sodium carbonate, 2.5% by weight of sodium phosphate, boil for 10 minutes, cool down to about 70°C, add 5.0% by weight of ethanol, and finally add water to dilute to obtain cleaning agent composition A1, wherein the total Water is 84.8% by weight.

[0020] At room temperature, the optical grade polycarbonate (PC) sheet was placed in the cleaning agent composition A1 for cleaning for 10 minutes, and then rinsed with water. It was found that the PC sheet was completely soaked by water. Electroform the PC sheet after metallization, and then observe it with a 10-fold magnifying glass.

Embodiment 2

[0022] Mix 2% by weight of sodium lauryl ether phosphate and 2% by weight of coconut acid diethanolamide with water to form a mixture, add to boiling water, stir to dissolve, then add 10.0% by weight of potassium carbonate, 5.0% by weight of sodium silicate , 10.0% by weight of potassium hydroxide, boiled for 10 minutes, cooled to about 70°C, added 15.0% by weight of ethanol and 15.0% by weight of methanol, and finally diluted with water to obtain cleaning agent composition A2, wherein the total water is 41.0% by weight.

[0023] Under room temperature conditions, the optical-grade acrylic resin (PMMA) sheet was placed in the cleaning agent composition A2 and cleaned for 15 minutes, and then rinsed with water. It was found that the PMMA sheet was completely soaked in water, and the PMMA sheet was metallized. Electroformed, then observed with a 10x magnifying glass.

Embodiment 3

[0025] Mix 0.02% by weight of potassium lauryl ether phosphate and 0.02% by weight of coconut acid diethanolamide with water to form a mixture, add it to boiling water, stir to dissolve it, add 2.0% by weight of sodium hydroxide, and boil for 10 minutes. Cool down to about 70°C, add 1.0% by weight ethanol, and finally add water to dilute to obtain cleaning agent composition A3, wherein the total water is 96.96% by weight.

[0026] At room temperature, the optical-grade methyl methacrylate and styrene copolymer (NAS) sheet was placed in the cleaning agent composition A3 for cleaning for 15 minutes, and then rinsed with water. It was found that the NAS sheet was completely soaked in water. Electroform the NAS sheet after metallization, and observe it with a 10x magnifying glass.

Abstract

A water-soluble cleaning agent composition comprises an alkaline compound, polyoxyethylene laurylether phosphate salt, lauric acid diethanolamide, lower alcohol and water; taking the total weight of the composition as benchmark, the content of the alkaline compound is 0.01-5 percent by weight, the content of the polyoxyethylene laurylether phosphate salt is 0.01-5 percent by weight, the content of the lauric acid diethanolamide is 0.01-5 percent by weight, the content of the lower alcohol is 0.1-40 percent by weight, and the rest is the water. The cleaning agent composition is easy to be dissolved in a water-organic matter system, can be dissolved in water by any proportion and has strong oil-removing and cleaning ability at normal temperature without causing residual surfactant on the surface of the cleaned object.

Description

technical field [0001] The invention relates to a water-soluble cleaning agent composition, in particular to a water-soluble cleaning agent composition used for precision electroforming mold templates. Background technique [0002] Precision optical molds or holographic embossing templates use plastics with precise patterns as masters, and are made by electroforming after cleaning and degreasing processes. The manufacture of precision optical molds or holographic molding templates is precision processing, the spatial frequency of the relief stripes is above 1000 lines / mm, and the average depth of the relief stripes is only a fraction of the wavelength of light. Precision optical molds or holographic mold embossing stencils require bright layout, clear patterns, fine and uniform, and no dendrites, sponges, stripes, black spots, spots, roughness, burnt black, peeling, bubbles and other defects are allowed. [0003] CN 1287142A discloses a water-based cleaning agent product, a...
