Technical Field

[0001] The utility model relates to the field of ABS composite boards, in particular to a low-temperature resistant and impact resistant ABS composite board. Background Art

[0002] ABS composite panels are usually composed of two layers of ABS plastic with other materials sandwiched between them. These sandwich materials can provide enhanced performance, increase surface gloss, enhance wear resistance or improve other characteristics. ABS composite panels are widely used in various industries, such as automotive interiors, electronic product housings, furniture parts, building materials and decorative panels.

[0003] After searching, a composite plastic board with good low-temperature resistance and impact resistance with announcement number CN214821564U includes an ABS plastic thin plate, which can play a certain impact resistance role. A second polyamide-imide foam plate and a first polyamide-imide foam plate are bonded on both sides of the ABS plastic thin plate, which improves the impact resistance of the composite board and improves the stability and toughness of the board. An anti-ultraviolet film and a first polytrifluorochloroethylene film are bonded to the outer side of the first polyamide-imide foam plate in sequence, which improves the anti-ultraviolet ability of the board and improves the brittleness resistance of the board. A second polytrifluorochloroethylene film is bonded to the outer side of the second polyamide-imide foam plate, which improves the low-temperature resistance of the board.

[0004] Based on the above patent, the plastic plate mentioned in its background technology has good stability and can be subjected to secondary processing such as heating and electroplating on its surface, but its impact resistance cannot be stably improved, and the low temperature resistance of the plastic plate, that is, the brittleness resistance effect is not good. In order to improve the low temperature resistance and impact resistance of the composite plastic plate and improve the scope of use of the plastic plate, a new type of composite plastic plate is proposed. In this regard, in response to this technical problem, this application proposes a low temperature resistant and impact resistant ABS composite plate. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-4 The utility model provides an embodiment: a low-temperature resistant and impact-resistant ABS composite board, comprising an external impact layer 1, the inner side of the external impact layer 1 is fixedly connected with a support reinforcement layer 2, the inner side of the support reinforcement layer 2 is evenly provided with a plurality of anti-slip limit grooves 7, the inner side of the support reinforcement layer 2 is fixedly connected with an inner support cold-resistant layer 3, the inner side of the inner support cold-resistant layer 3 is evenly provided with a plurality of installation limit grooves 6, the installation limit grooves 6 are connected to the anti-slip limit grooves 7 through a plurality of anti-slip support components, the anti-slip support components include an arc-shaped support block 4 located inside the installation limit groove 6, the upper and lower sides of the arc-shaped support block 4 are fixedly connected with limited anti-slip sheets 5, the outer sides of the arc-shaped support block 4 are respectively correspondingly inserted into the inner side of the support reinforcement layer 2, and the outer sides of the limited anti-slip sheets 5 are respectively correspondingly nested in the anti-slip limit grooves 7;

[0025] When the board is subjected to impact force from the outside, the impact force first contacts the surface of the external impact layer 1, so that a part of the transmitted impact force is alleviated by the external impact layer 1, and the impact force continues to be transmitted inward to contact the outside of the support reinforcement layer 2. The support reinforcement layer 2 is a glass fiber layer with high tensile strength and elastic modulus. The multiple arc-shaped support blocks 4 inside stretch the support reinforcement layers 2 on both sides, and the force will penetrate into the interior of the arc-shaped support blocks 4 through the support reinforcement layers 2, thereby offsetting them, further increasing the board's resistance to impact force, thereby improving the support safety of the board and extending its service life.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The supporting and reinforcing layer 2 is a glass fiber layer, which has excellent properties such as light weight, high strength, corrosion resistance and insulation. The external impact layer 1 is an ABS resin layer with butadiene added, and the inner supporting cold-resistant layer 3 is an ABS resin layer with acrylonitrile and styrene added;

[0027] The interior of the external impact-resistant layer 1 is ABS resin with a larger dosage of butadiene, which can improve the toughness and impact strength of the ABS resin. The inner supporting cold-resistant layer 3 is a resin layer with acrylonitrile and styrene, which can improve the rigidity and hardness of the ABS resin and improve the resistance. The ABS resin can still maintain a certain toughness and impact resistance at a lower temperature. The low-temperature working temperature of ABS resin is usually between -20°C and -30°C. In a low-temperature environment, the board can also work normally, which increases the cold resistance of the board, thereby making the board applicable to a wider environment and improving the applicability of the board.

[0028] Working principle: When the board is subjected to external impact, the impact force first contacts the surface of the external impact layer 1, and the transmitted impact force is partially alleviated by the external impact layer 1, and the impact force continues to be transmitted inward to contact the outside of the support reinforcement layer 2. The support reinforcement layer 2 is a glass fiber layer with high tensile strength and elastic modulus. The internal multiple arc-shaped support blocks 4 hold open the support reinforcement layers 2 on both sides, and the force will penetrate into the interior of the arc-shaped support blocks 4 through the support reinforcement layers 2, thereby offsetting them. In addition, ABS resin can still maintain a certain toughness and impact resistance at lower temperatures. The low-temperature working temperature of ABS resin is usually between -20°C and -30°C. In low-temperature environments, the board can also work normally.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
