Embodiment Construction

[0041] The embodiment discloses a method for preparing a surface layer material of a directional reflective film, comprising the following steps:

[0042] 1. Preparation of hard acrylic resin:

[0043] a), the following components are prepared according to the corresponding percentages by weight, and the xylene and butyl acetate are mixed to obtain a solvent mixture, and 4 / 5 parts by weight of the solvent mixture are placed in the reaction still, and heat the solvent mixture in the reaction kettle to 120°C and keep stirring; the reaction kettle involved in this step is a common chemical equipment, which has a stirring function and a heating function, and is well known to those skilled in the art. Equipment, 4 / 5 parts by weight is relative to the total amount of dimethylbenzene and butyl acetate in this step. As for the heating temperature, the experimental results show that there is no obvious impact on the finished product within the range of 120 °C plus or minus 5 °C. , the...

Abstract

The invention provides a preparation method of oriented reflective membrane surface material with lower cost and better physiochemical performance. The method comprises the following steps: placing the prepared acrylic monomers in a certain ratio such as methyl methacrylate, butyl methacrylate, hydroxy-propyl acrylate, acrylic acid and polycaprolactone acrylate and benzoyl peroxide in a head tank, dropping the solution in a reaction tank containing a mixed solvent of dimethylbenzene and butyl acetate at a uniform speed, simultaneously dropping a benzoyl peroxide mixed solution in the reaction tank, reacting at 120 DEG C to obtain glue solution, then adding curing agent and mixed organic solvent to reach a set viscosity, and finally coating the glue solution with a machine to prepare the oriented reflective membrane surface material. The surface material is mainly used as the surface of the products of advertisement grade reflective membranes, engineering grade reflective membranes, number plate grade reflective membranes, high strength grade reflective membranes, car body adhesive films and the like.

Description

technical field [0001] The invention relates to the technical field of directional reflective film, in particular to a preparation method for surface material of directional reflective film. The prepared surface material of directional reflective film is used for advertising grade reflective film, engineering grade reflective film, license plate grade High-grade reflective film and body film and other fields. Background technique [0002] Advertising-grade reflective film, engineering-grade reflective film, license plate-grade reflective film, high-strength reflective film and body stickers belong to the series of directional reflective film products. They are a new material for basic optical applications. Their common feature is that they can direct the incident light back Reflective, produce bright reflective effect, obtain colorful visual senses, use reflective film to make various types of reflective products such as labels, signs, signs, grades, etc., which can effectiv...
