Problems solved by technology

[0004] However, although the water-based system DLP 3D printing photosensitive resin is prepared by using water-based monomer and water-based polyurethane resin as raw materials to improve the elongation at break, its fatigue resistance is crossed, and it does not have excellent weather resistance. Thus affecting the practicability and market acceptance, needs to be improved

Abstract

The invention discloses a preparation method and a production device of a resin adhesive, and relates to the technical field of adhesives, and the key point of the technical scheme of the preparation method comprises the following steps: (1) introducing diethoxy bisphenol A diallyl ester into a treatment stirrer, stirring for 10 minutes, and carrying out ultrasonic dispersion on the stirred diethoxy bisphenol A diallyl ester for 40 minutes to obtain a mixed primary material; (2) introducing hydrogenated bisphenol A epoxy resin, a reactive diluent, a cationic initiator, a photoinitiator, a filler, a flexibilizer, a solvent and the mixed primary material into a mechanical stirrer, stirring at a high speed for 3-4 hours, and naturally curing to obtain mixed slurry; and (3) carrying out vacuum drying treatment on the mixed slurry to obtain the photosensitive resin material. The photosensitive resin material has the effect of obtaining the photosensitive resin material with high tensile strength, good anti-fatigue performance and excellent weather resistance, and the active diluent is adopted to effectively cooperate with other components according to the weight part ratio of 49.3-51.3, so that the purpose of improving the physical performance of the obtained photosensitive resin material is achieved.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a method for preparing a resin adhesive and a production device thereof. Background technique [0002] 3D printing technology, also known as rapid prototyping manufacturing and additive manufacturing technology, has been frequently reported in major news reports in the past two years. However, the concept of 3D printing is not just emerging. Its core manufacturing idea first originated in the United States at the end of the 19th century. By the late 1980s, 3D printing technology had been developed and widely known. The reason why rapid prototyping manufacturing technology has become popular in a short period of time, and even known as the "third industrial revolution", is mainly based on "faster", "more refined", "less expensive" and "more suitable for industrial production". "It completely outperforms the existing industrialized production methods. [0003] The Chinese paten...
