Embodiment 1

[0048] Take 50Kg of crystal waste residue, and carry out preliminary screening on the waste residue through a vibrating sieve (with a sieve hole diameter of 0.5 mm) to remove impurities and large particles. Then put the sieved crystal waste into the ball mill and grind it finely. The outlet sieve diameter of the ball mill is 400 mesh (about 33 microns). Then the finely ground crystal waste residue is dehydrated through a three-legged centrifuge, and dried in an oven until the water content is lower than 0.03%. Carry out surface coating treatment to crystal waste slag again: (1) in kneader machine, quantitative crystal waste slag is heated to 110 ℃; 20 minutes; (3) adding 1% by weight (based on the quantitative crystal waste weight) of organic silicon, and mixing for 20 minutes to obtain activated crystal waste particles. Fill the crystal waste slag into polypropylene (in), the filling amount is 10% (by weight of polypropylene): mix the weighed activated crystal waste slag and...

Embodiment 2

[0050] The treatment process of crystal waste residue is the same as in Example 1, except that the diameter of the sieve hole at the outlet of the ball mill is 300 mesh. The crystal waste slag was filled into polypropylene, and its mechanical properties were tested. The results are shown in Table 2.

Embodiment 3

[0052] The treatment process of crystal waste residue is the same as in Example 1, except that the diameter of the sieve hole at the outlet of the ball mill is 600 mesh. The crystal waste slag was filled into polypropylene, and its mechanical properties were tested. The results are shown in Table 2.

Abstract

The invention discloses a method for preparing a plastic filler from waste residue in the crystal industry. The method comprises the following steps of: (1) primarily screening the waste residue by using screening equipment to remove impurities and large particles; (2) grinding the waste residue by using grinding equipment, and finely screening; (3) dehydrating and drying particles of the waste residue; and (4) performing surface coating treatment on the particles of the waste residue by using a surfactant to obtain a highly activated inorganic filler capable of being directly filled in plastics. The waste residue is properly treated to form the filler applied to the plastics; and by the method, a great amount of waste residue generated in the crystal industry can be recycled, the pollution of the waste residue on the environment is lightened, the exploitation of inorganic minerals is saved, and good social benefit is achieved.

Description

technical field [0001] The invention relates to a method for preparing plastic fillers by utilizing waste residues in the crystal industry, and specifically relates to obtaining fillers that can be directly filled in plastics by controlling particle size and surface treatment of waste residue particles, the purpose of which is to realize solid waste recycling. Resource recycling belongs to the field of environmental protection. Background technique [0002] The crystal industry takes crystal glass (usually high-lead glass) as the initial raw material, and processes it into various shapes of glass products with crystal characteristics through mechanical cutting, grinding, polishing and other means. During the processing of crystal products, a large amount of waste residue will be brought. According to statistics, every ton of crystal glass processed will produce 30% waste residue. For small products, the amount of waste residue will be even greater, and only in the Pujiang ar...
