Problems solved by technology

[0003] At present, most cleaning agents are still based on phosphate, but phosphate is highly polluting, causing environmental pollution, deterioration of ground water, and threatening human health. At the same time, cleaning agents with a higher pH value are also easy to The PET base material and the surface of the base material after coloring cause discoloration. Therefore, it is necessary to develop a PET plastic sheet cleaning agent that is environmentally friendly and does not easily damage product quality.

Embodiment 1

[0052] A cleaning agent for PET plastic plates, consisting of the following components in percentage by weight:

[0053] Narrow molecular weight distribution Gubert alcohol polyoxyethylene ether (5EO) 4.6%;

[0054] Sodium hydroxide 3.5%;

[0055] Citric acid 4.5%;

[0056] Isooctanoic acid 2.2%;

[0057] Oxalic acid 2.3%;

[0058] Lauryl dimethyl ammonium chloride 2.3%;

[0059] Alcohols 3.5%;

[0060] Deionized water balance.

[0061] Among them, alcohols are composed of 98% isohexanediol and 2% butanol. Citric acid is citric acid monohydrate.

[0062] The preparation method of above-mentioned PET plastic plate cleaning agent is as follows:

[0063] Step A: Add potassium hydroxide, citric acid, oxalic acid and isooctanoic acid to the deionized water in sequence according to the weight percentage, adjust the reaction temperature to 40-50°C, adjust the pH value to 8.0-8.5, stir and mix, and the stirring time 30 minutes, stirring speed is 100 ~ 200rpm.

[0064] Step B...

Embodiment 2-6

[0067] A cleaning agent for PET plastic plates, the difference from Example 1 is that the dosage of each component of the cleaning agent for PET plastic plates is different, see Table 1 for details.

[0068] Each group distribution ratio of table 1 embodiment 1-6

[0069]

Embodiment 7

[0071] A cleaning agent for PET plastic plates, consisting of the following components in percentage by weight:

[0072] Narrow molecular weight distribution Gubert alcohol polyoxyethylene ether (5EO) 4.8%;

[0073] Sodium hydroxide 3.8%;

[0074] Citric acid 4.2%;

[0075] Isooctanoic acid 2.5%;

[0076] Oxalic acid 2.4%;

[0077] Lauryl dimethyl ammonium chloride 2.2%;

[0078] Alcohols 4.0%;

[0079] Deionized water balance.

[0080] Wherein, the alcohol substance is a single component of isohexanediol.

[0081] The preparation method and usage method of the cleaning agent for PET plastic plates in this embodiment are the same as those in Embodiment 2, and will not be repeated here.

Abstract

The invention relates to the technical field of industrial cleaning agents, in particular to a PET plastic plate cleaning agent and a preparation method and a use method thereof. The PET plastic plate cleaning agent comprises narrow molecular weight distribution Guerbet alcohol polyoxyethylene ether (5EO), sodium hydroxide, citric acid, isocaprylic acid, oxalic acid, dodecyl dimethyl ammonium chloride, alcohol substances and deionized water. The preparation method comprises the following steps: stirring and mixing deionized water, potassium hydroxide, citric acid, oxalic acid and isocaprylic acid, sequentially adding narrow-molecular-weight-distribution Guerbet alcohol polyoxyethylene ether (5EO), dodecyl dimethyl ammonium chloride and alcohol substances, and stirring and mixing to obtain the PET plastic plate cleaning agent. By using the PET plastic plate cleaning agent disclosed by the invention, not only is the quality of a product not easily influenced, but also the safety and environment-friendly performance are improved.

Description

technical field [0001] The invention relates to the technical field of industrial cleaning agents, more specifically, it relates to a cleaning agent for PET plastic plates and its preparation method and use method. Background technique [0002] Industrial cleaning occupies an important position in surface treatment and is an indispensable pre- and post-treatment process in surface treatment. A suitable industrial cleaning agent has excellent cleaning performance, does not damage the substrate, is easy to rinse, and is highly efficient and environmentally friendly. It can increase production capacity, ensure product quality, and reduce production costs. In recent years, due to the continuous improvement of mobile phone surface treatment technology, the continuous emergence of advanced surface coloring, the development of technology and workpiece materials, the development of industrial cleaning technology has been promoted. With the increasing investment of PET materials in ...
