Problems solved by technology
[0004] The general disadvantage of thermoplastic resins is that they are poor in rigidity and easy to break after being subjected to external forces. To improve their toughness, most of them currently use complex production processes and adjust production formulas to enhance their tensile and bending strength. not tall

Embodiment
[0046] see Figure 1-6 , a production process for high-toughness thermoplastic resins, see Image 6 , including the following steps:
[0047] S1, the thermoplastic resin body 1 is first broken into pellets, then the pellets are put into the heating furnace, the temperature is raised to the melting temperature of the thermoplastic resin body 1, and then the heating is stopped, and the heat preservation is started;
[0048] S2, put the flexible body 2 into the molten thermoplastic resin body 1, and mix and stir, and add an appropriate amount of volatile silicone oil during the stirring process to eliminate air bubbles;
[0049] S3, after stirring evenly, pour the mixture of the thermoplastic resin body 1 and the flexible body 2 into the mold for curing, first lay a layer of heat-resistant layer 3 on the bottom of the mold, and then smooth the upper surface after the mixture is poured, and then lay a layer of heat-resistant layer 3. Thermal Layer 3.
[0050] see Figure 4 In ...

The invention discloses a production process of high-toughness thermoplastic resin, which belongs to the field of resin production. A production process of high-toughness thermoplastic resin comprises the following steps: S1, firstly crushing the thermoplastic resin body into granules, and then putting the granules into In the heating furnace, the temperature is raised to the melting temperature of the thermoplastic resin body, and then the heating is stopped, and the heat preservation is started. The shell is made of polyurethane material, which has a certain elasticity. The elastic mesh inside the flexible body can resist stretching and bending. It can effectively improve the toughness of the thermoplastic resin in cooperation with the elastic shell. The connection reinforcement extension outside the elastic shell can effectively improve the connection strength. The heat layer can effectively increase the heat resistance temperature of the resin, and the connection reinforcing extension piece can transfer part of the heat of the resin to the heat absorbing film inside the flexible body, thereby effectively improving the heat resistance of the resin.
Description
technical field [0001] The invention relates to the field of resin production, and more particularly, to a production process of a high-toughness thermoplastic resin. Background technique [0002] Resin usually refers to an organic polymer that softens or melts after being heated, tends to flow under the action of external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for processing plastic products is called resin. Resins are divided into natural resins and synthetic resins. Natural resin refers to the amorphous organic substances obtained from the secretions of animals and plants in nature, such as rosin, amber, shellac, etc. Synthetic resin refers to the resin product obtained by chemical synthesis of simple organic matter or chemical reaction of some natural products, such as phenolic resin, polyvinyl chloride resin, etc., of which synthetic resin is the ...
