[0004] The above-mentioned existing technical solutions have the following defects: the anti-compression layer on the ABS board improves the compressive strength of the composite board, but when the anti-compression layer is combined with ABS, the different proportions of the raw material components in the anti-compression layer will cause the board to produce Different effects, the pressure-resistant layer does not have a metering device to control its content during the extrusion process, so the above technical solution needs to be improved

Embodiment 1
[0044] refer to image 3 , is a kind of ABS plate processing method disclosed by the present invention, comprises the following steps:
[0045] Step 1, prepare materials, inject ABS raw materials, ASA raw materials, PMMA raw materials and sound insulation raw materials into four mixers, start the mixers, and mix the raw materials evenly;
[0046]Step 2: thermoplastic, the extruder heats the raw material;
[0047] Step 3, exhaust, the water vapor in the raw material after hot melting is discharged from the vent hole of the barrel;
[0048] Step 4, quantification, quantitative extrusion of ABS raw materials, ASA raw materials, PMMA raw materials and sound insulation raw materials;
[0049] Step 5: Fixing the mould, injecting raw materials into five groups of corresponding mold cavities in the mould, and making a five-layer composite board.
[0050] The first choice is to put the ABS raw material, ASA raw material, PMMA raw material and sound insulation raw material into four ...
Embodiment 2
[0057] refer to figure 2 , is a kind of processing ABS plate equipment disclosed by the present invention, comprises frame 1, mold 17 and four groups of extruders, and described extruder has the equipment that is used for injection molding in the prior art, and extruder comprises barrel 2 As well as the screw blade 3, the four groups of barrels 2 are respectively injected with ABS raw materials, ASA raw materials, PMMA raw materials and a mixture of polyamide fiber and glass fiber, and the thermoplastic temperature of PMMA raw material is 190-240 ° C, and the thermoplastic temperature of ASA raw material is 180-220°C, the thermoplastic temperature of ABS raw material is 185-230°C, and the thermoplastic temperature of polyamide fiber and glass fiber is 215-220°C; the temperatures in the four sets of barrels 2 correspond to the corresponding temperatures of different raw materials.
[0058] refer to figure 2 , in order to facilitate the control of the injection amount of raw ...

Abstract
The invention discloses an ABS board machining method and equipment. The method comprises the following steps of 1, preparing materials, specifically injecting ABS raw materials, ASA raw materials, PMMA raw materials and sound insulation raw materials into four stirring machines, starting the stirring machines, and uniformly stirring the raw materials; 2, heating plastic, specifically heating theraw materials through an extruding machine; 3, exhausting air, specifically discharging water vapor in the raw materials after hot melting from an air exhaust hole of a material barrel; 4, quantifying, specifically quantitatively extruding the ABS raw materials, the ASA raw materials, the PMMA raw materials and the sound insulation raw materials; and 5, molding, specifically injecting the raw materials into five corresponding mold cavities in a mold to producing a composite board with five layers of structures. According to the technical scheme, the proportion of different raw materials can bequantified, ABS boards with different functions can be machined and produced, and the production efficiency of the ABS boards is improved.
Description
technical field [0001] The invention relates to the technical field of plate processing, in particular to an ABS plate processing method and equipment. Background technique [0002] ABS sheet is widely used in various industries at present. The sheet made of ABS plastic is a kind of tough, hard and rigid material with easy-to-obtain raw materials, good comprehensive performance, low price and wide application. , automobile, aircraft, shipbuilding and other industries and chemical industry are widely used; ABS plastic is a terpolymer of acrylonitrile-butadiene-styrene, the properties of the three components are not the same, which also creates different properties ABS sheet; adjusting the ratio of the three components of ABS, its performance will also change to meet the requirements of various applications, such as high-resistant ABS, heat-resistant ABS, high-gloss ABS, etc., but pure ABS still cannot satisfy people. Due to the increasingly diverse needs, composite ABS sheet...
