[0104] Implementation

[0105] The present invention will be further explained below in conjunction with the drawings:

[0106] Figures 1 and 2 show the process flow chart for the rapid preparation and molding of photosensitive resin. Each preparation parameter must be strictly controlled and operated in order.

[0107] For the preparation of the chemical materials required for molding, epoxy resin (E-51), acrylic acid, N,N-dimethylaniline, p-hydroxyanisole, isopropyl thioxanthone (ITX), trimethylol Propane triacrylate (TMPTA), silicon carbide whiskers, silane coupling agent (KH-560), anhydrous ethanol, methanol, and deionized water should be strictly selected, and purity controlled, and no impurities should be involved. Prevent the formation of by-products and affect the mechanical and physical properties of product parts.

[0108] The required chemical substances must be weighed in strict accordance with the proportion, and each value shall not exceed the maximum and minimum ran...

Abstract

The invention relates to a fast method for shaping resin composite material element, employing epoxy resin (E-51) and acrylic acid, carbonized silicon crystal whisker as intensifier, N,N-dimethylaniline as accelerant, p-methyl phenoxide as inhibitor, trimethylolpropane acrylate as diluting monomer, isopropyl thioxanthones as photo-initiation agent, silane coupling agent (KH-560) as modifier, and methanol as dissolvent. The method comprises following steps: synthesizing epoxy acrylate, diluting with trimethylolpropane acrylate, synthesizing photosensitive resin, synthesizing resin composite material miscible liquids with photosensitive resin and carbonized silicon crystal whisker, fast shaping element on photo-hardening shaping device, the composite material miscible liquid is controlled by ultraviolet light source, focusing lens focusing lens and computer program in electrode tank of X-Y-Z working bench. The invention provides a fast method for preparing injecting mold, flake grinder, ultra-thin element and accessory in special shape.

Description

technical field [0001] The invention relates to a rapid prototyping method for resin-based composite material parts, which belongs to the technical field of ultraviolet light curing rapid prototyping methods for resin-based composite material parts with photosensitive properties. Background technique [0002] Photosensitive resin is a high molecular polymer with good adhesion, good toughness and chemical stability. By adding a certain amount of reinforcing agent, the resin-based composite material prepared has strong adhesion and has With greater specific strength, wear resistance, corrosion resistance, high toughness and high mechanical properties, it has a wide range of application values ​​in industry, such as abrasive grinding wheels, wear-resistant and corrosion-resistant parts, tools, etc. [0003] Rapid prototyping technology, referred to as RP, is an industrial processing technology developed in the 1980s. Its process methods include photosolidification, lamination, ...
