Problems solved by technology

[0004] The traditional ABS sheet has good strength, but insufficient toughness, high surface hardness, and is not suitable for large-scale bending. The main body of the ABS board and the cladding layer are bonded by glue. The glue is prone to failure after long-term high-temperature exposure, which will cause the board to peel off and seriously reduce the service life.

Embodiment 1

[0035] Such as figure 2 Shown, the preparation method of a kind of ABS board material described in the embodiment of the present invention, this method is used for preparing above-mentioned ABS board material, comprises the following steps:

[0036] S1. Dry the prepared ABS composite material, then put the composite material into the extruder, heat it to a molten state, extrude and granulate it, and then cool it to room temperature, and vibrate continuously during the cooling process to prevent the particles from sticking together, and obtain granule A ;

[0037] S2. Put the granule A prepared in S1 into a high-speed mixer, then add the crosslinking agent of the corresponding component and stir fully to obtain the mixture B;

[0038] S3. Put the mixture B into the extruder, heat it to form a fluid in a molten state, and then extrude the body 1 with the through groove 13 after being shaped through the extrusion port 22, and at the same time pass the conveyer belt 26 to the in...

Embodiment 2

[0046] Such as Figure 5 As shown in Comparative Example 1, another embodiment of the present invention is: an annular groove 43 is provided on the end surface of the circular ring 310 close to the conveyor belt 26, and a sealing ring 44 is arranged in the annular groove 43, and the sealing ring The bottom of 44 is fixedly connected with the bottom of the annular groove 43, and the top of the sealing ring 44 is closed towards the direction close to the center of the ring 310; the bottom of the annular groove 43 corresponding to the inner circumference of the sealing ring 44 is provided with a blind hole 45, and slides in the blind hole 45. A sliding pin 46 is connected; a spring is fixedly connected between the sliding pin 46 and the bottom of the blind hole 45; a partition 47 is fixedly connected to the position corresponding to the blind hole 45 in the water inlet pipe 36, and the upper and lower sides of the partition 47 Water pipe 36 communicates with blind hole 45 through...

Abstract

The invention belongs to the technical field of polymer composite materials, and particularly relates to an ABS plate and a preparation method thereof, the ABS plate comprises a body made of an ABS material and a coating layer; a wrapping layer is arranged on one side of the body in a hot pressing mode, a profiled groove is formed in one side of the body, and one side of the wrapping layer is embedded into the profiled groove. Arc-shaped through grooves are formed in the two sides of the bottom of the profiled groove, and the sections of the through grooves are major arcs; the whole through groove is filled with the coating layer; according to the invention, the coating layer is softened by heating and then is heat-sealed with the body, so that the connection strength is improved, the through groove and the profiled groove are matched, the local thickness of the body is reduced, the flexibility and toughness are improved, the falling between the body and the coating layer is reduced, the service life of the body is prolonged, and the bending modeling effect is improved.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, in particular to an ABS board and a preparation method thereof. Background technique [0002] ABS sheet is an emerging material in the sheet industry. Its full name is acrylonitrile / butadiene / styrene copolymer board. The English name Acrylonitrile-butdiene-styrene is a polymer with large output and wide application. It organically unifies the various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, hardness, and rigid phase balance. [0003] A Chinese patent with a publication number of 104530738B discloses a PP / ABS wood-plastic composite board and its preparation method. The wood-plastic composite board is prepared from the following materials in parts by weight: 60-80 parts of wood powder, PP / ABS Composite material 20-40 parts, lubricant 1-3 parts. The preparation method includes: (1) preparation of PP / ABS composite material; (2) prepa...
