Problems solved by technology

[0006] Currently on the market, organic solvents (white oil, alcohol or isopropanol and other organic solvents) are mainly used to clean the plastic surface. The advantage is that the cleaning is relatively clean, and the solubility of the organic solvent can be adjusted according to different substrates; the disadvantage is that the cost is high. Not environmentally friendly, affecting the health of operators

Abstract

The invention discloses a surface treating agent applicable to a toy plastic material and a preparation method thereof. The raw material formula of the surface treating agent consists of sodium laureth sulfate, laurinol disodium stearamido measulfosuccinate, lauramide propyl gydroxysulfobetaine, cocamide MEA, polyquaternium-7, ethylenediaminetetraacetic acid disodium salt, 1,3-dihydromethyl-5,5-dimethyl hydantion and dilute phosphoric acid. The surface treating agent can be applied to performing surface pretreatment on toy plastic materials such as acrylonitrile butadiene styrene (ABS) / polyvinyl chloride (PVC) and the like before coating. In the formula of the surface treating agent, environment-friendly materials are adopted completely, so the discharging quantity of volatile organic compounds (VOC) is close to 0. Compared with the traditional solvent type clean treating agent, the surface treating agent has better cleaning effect and better coating effect of the coating. The surfacetreating agent has a simple preparation method and low cost of the raw material formula, and can meet requirements of toy manufacturers and requirements of national low-carbon economy.

Description

technical field [0001] The invention relates to a surface treatment process of plastic materials, in particular to a surface treatment agent suitable for toy plastic materials and a preparation method thereof. Background technique [0002] At present, the vast majority of the toy market uses plastic materials such as ABS\PVC, and paints are used to present the ornamental properties of toys. The first step is crucial. [0003] ABS (acrylonitrile-butadiene-styrene copolymer), which is a thermoplastic resin plastic material, has strong mechanical properties and processing properties. When painting, problems such as poor adhesion, loss of gloss and pitting often occur. The main reasons are: the surface tension is less than 100Mm / cm, the solubility parameters are quite different from the solubility parameters of the resin and solvent in the paint, the surface is prone to static electricity and dust absorption during molding, and the stripping method used for easy demoulding duri...
