Abstract
The invention discloses a regenerated modified ABS material and a preparation method and application thereof. The regenerated modified ABS material comprises the following components in parts by weight: 50 to 95 parts of regenerated ABS resin, 1 to 15 parts of aging repair agent, 1 to 5 parts of compatilizer, 0.1 to 1 part of antioxidant, 0.1 to 2 parts of processing aid, 0.05 to 1 part of colorant and 0.05 to 1 part of diffusion oil. The material has better strength, normal temperature impact resistance and low temperature impact resistance, has smooth product surface and no pock, and can be used for storage battery shells, in particular lead-acid storage battery shells; compared with the production of the storage battery shell by adopting new materials, the invention reduces the cost; the preparation process is simple, the industrial production is easy, the double-stage extrusion process of the upper-stage double screw and the lower-stage single screw is adopted, the material is pure, the plasticization is uniform, the color is consistent, and the problems of environmental problems and resource waste caused by a large number of ABS plastic shells of electronic appliances are solved.
Description
Technical Field
The invention relates to the technical field of high polymer materials, in particular to a regenerated modified ABS material and a preparation method and application thereof.
Background
At present, ABS shells used for storage battery shells in the existing market are new materials and reclaimed materials. The ABS material has good performance, but is expensive, the cost burden of manufacturers is increased, and meanwhile, the ABS plastic shell of the household electrical appliance is not fully recycled at a high value, so that the waste of resources is caused. At present, the reclaimed materials mainly comprise the reclaimed materials such as storage battery shell ABS crushed materials, medical instrument ABS plastic shells and the like. However, the recovery of medical instruments is limited in ABS source, high in recovery cost, possibly causing medical and health pollution problems, and insufficient in low-temperature impact resistance. The impact performance of the ABS broken material of the storage battery shell is obviously reduced due to the influences of acid corrosion and charge and discharge after the ABS broken material is recovered for many times, and the broken material contains more epoxy resin sealing adhesive which is not easy to clean completely, so that impurity defects can be caused, and the strength and the surface smoothness of a product are influenced. In addition, lead is contained in the ABS of the lead-acid storage battery shell, and lead pollution is easy to cause in the recovery process.
Disclosure of Invention
Based on the above, the invention aims to overcome the defects of the prior art and provide a regenerated ABS material and a preparation method and application thereof. The regenerated ABS material obtained by the preparation method is added with auxiliary materials such as an aging repair agent and the like for performance improvement, and the obtained regenerated modified ABS material has good strength, normal temperature impact resistance and low temperature impact resistance, has smooth product surface, no pits and low cost, and can be used as a storage battery shell material.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: a preparation method of regenerated ABS resin comprises the following steps:
1) Metal separation: separating metals from the recycled ABS plastic shell of the electronic appliance by using a magnetic machine, wherein the magnetic flux of a magnetic rod is 10000-15000 gauss;
2) Crushing: crushing by a crusher, wherein the size of the screen is 10-40 mm;
3) Density sorting: sodium chloride solution with the concentration of 5-10 Baume degrees is adopted as a sorting medium for sorting;
4) Cleaning: washing with circulating water to a baume degree of less than 0.5;
5) Dehydrating and drying: removing water to below 2% by using a centrifugal dehydrator, and drying to below 0.5% by using a forced air drying device;
6) Electrostatic sorting: adopting a high-voltage electrostatic separator to separate the ABS with the purity of more than 98% at a voltage of 3-6 kilovolts;
7) Silica gel separation: and (3) performing silica gel separation by adopting a roller type silica gel separator at a roller rotating speed of 40-50 rpm to obtain the regenerated ABS resin.
The regenerated ABS resin is crushed material of ABS plastic shells of electronic appliances after impurity removal treatment, and the electronic appliances comprise televisions, printers, copiers and the like. The electronic and electric appliance shell has higher rigidity and heat resistance, can avoid the bellyband expansion of the storage battery shell, has lower cost, has color matching property and can produce storage battery shells with different types and colors. The reclaimed material for the ABS plastic shell of the electric appliance contains impurities such as PC, PC/ABS alloy, PA, silica gel, silt, wood dust, paper, foam, paint and the like, and the appearance and normal low-temperature impact of the material can be adversely affected without treatment and modification, so that the reclaimed material is not suitable for the shell of the storage battery. Therefore, the reclaimed ABS plastic shell of the electronic appliance is subjected to metal separation, crushing, density separation, cleaning, dehydration drying, electrostatic separation and silica gel separation steps to remove impurities, so that the reclaimed ABS resin is obtained. The density of the regenerated modified ABS resin is 1.03-1.05 g/cm 3 The melt index is 5-50 g/10min under the conditions of 220 ℃ and 10kg load.
Preferably, the screen size of step 2) is 15-25 mm.
Step 3) adopting sodium chloride solution with concentration of 5-10 Baume degrees to carry out density sorting to obtain the density of 1.03-1.05 g/cm 3 ABS material of (C); preferably, the concentration of the sodium chloride solution in the step 3) is 6-8 Baume degrees. If sodium chloride solution with the concentration less than 5 Baume degrees is adopted for density sorting, most of ABS materials can sink together with high-specific gravity impurities and cannot be sorted out due to the fact that the sorting liquid density is too low; if sodium chloride solution with concentration of more than 10 Baume degrees is adopted for density sorting, the obtained ABS material is doped with higher contentThe flame retardant, glass fiber or filler-containing ABS, filler PP and other impurities. The ABS material obtained after density separation is doped with a small amount of PS, filling PP and the like, and needs to be further subjected to electrostatic separation and removal. Finally, silica gel separation is carried out, so that impurities such as silica gel, elastomer and the like in the electronic and electric materials can be effectively removed. Without this step, the impact properties of the material would be affected, and the unmelted silica gel would form more pits and pits during the plating.
The electrostatic separation adopts 3-6 ten thousand volts, if the voltage is too low, the electric field strength can not separate ABS from PS and PP well, and the too high voltage easily causes equipment leakage and equipment stability is poor.
