Description

Technical Field

[0001] The invention relates to the technical field of polyurethane fiber processing, in particular to a polyurethane fiber prepreg curing and molding device. Background Art

[0002] Polyurethane fiber is a kind of polyurethane dissolved in organic solvents such as dimethylformamide, dimethylacetamide or dimethyl sulfoxide to obtain a spinning solution, which is then dry-spun or wet-spun into fibers, and then passed through an aqueous solution containing a fatty diamine chain extender to obtain elastic polyurethane fibers. Prepreg is a combination of a resin matrix and a reinforcement made by impregnating continuous fibers or fabrics with a resin matrix under strictly controlled conditions.

[0003] The curing system includes curing agent, accelerator, catalyst and diluent, etc. According to the use requirements of prepreg, prepreg needs to have a certain storage period at room temperature, so the curing system usually uses a latent curing agent, which means that it does not react with the resin at room temperature and pressure, but under special temperature and pressure, it will promote the cross-linking and curing reaction of the resin. This type of curing agent is usually a dispersed curing agent, that is, it is solid at room temperature and cannot be dissolved in epoxy resin, but when heated to near its melting point, it can be miscible with epoxy resin and start a rapid curing reaction.

[0004] The existing device mainly places the prepreg in a curing device for heating and curing. The existing technology is similar to a method and curing molding equipment for efficiently curing large-size carbon fiber prepreg. The curing method with patent number CN115091785A includes placing the carbon fiber prepreg in a curing device and compressing the carbon fiber prepreg; placing the carbon fiber prepreg under closed conditions and a nitrogen atmosphere, and using an array microwave generator to preheat the top and bottom of the carbon fiber prepreg. During the preheating process, the total power of the array microwave generator is 300-500W, and the temperature is raised to 80-100°C for a retention time of 5-10min; the preheated carbon fiber prepreg is subjected to microwave curing, the total power of the array microwave generator is 600-1000W, the curing temperature is 120-180°C, and the retention time is 40-60min, so as to obtain a cured carbon fiber felt. The method of the invention can effectively improve the curing effect and weaken the arc phenomenon, solving the problems of low yield and easy damage to equipment in the existing use of microwave heating technology to cure carbon fiber prepreg. However, there are still areas that can be optimized.

[0005] The existing device mainly places the prepreg in the curing device for overall curing processing, which makes it difficult for some devices to stably unfold and convey the fiber prepreg, thereby causing some devices to have difficulty in gradually heating and curing the fiber prepreg. Secondly, some devices mainly drive the material roll to rotate at a uniform speed by rotating the main shaft, so that the material feeding rate of the material roll of some devices will gradually change with the radius of the material roll, thereby causing some fiber line materials to be subjected to a certain tension during the feeding and heating process. Finally, some devices mainly cure the conveying line material through the heating component, which makes it difficult for some devices to drive the fiber line material through the guide roller and place it under the guide cover for smooth feeding, thereby causing some devices to be inconvenient for uniform heating of the fiber line material, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a polyurethane fiber prepreg curing and molding device is proposed. Summary of the invention
