specific Embodiment 1

[0010] Specific embodiment 1, the weight percent of each component in the vibrating material is: 94% magnesia, 5% composite binder, 0.5% coagulant, and 0.5% polycarboxylate superplasticizer.

specific Embodiment 2

[0011] Specific embodiment 2, the weight percent of each component in the vibrating material is: magnesia 96%, composite binder 3%, coagulant 0.8%, polycarboxylate superplasticizer 0.2%.

specific Embodiment 3

[0012] Specific embodiment 3, the weight percentage of each component in the vibrating material is: magnesia 95%, composite binder 4%, coagulant 0.6%, polycarboxylate superplasticizer 0.4%.

[0013] The method for preparing the above-mentioned no-bake magnesia vibrating material includes the following steps in sequence:

[0014] a) the massive magnesia is broken into large particles with a jaw crusher;

[0015] b) Use a roller crusher to crush the large particles into small particles with a particle size of 0-2 mm;

[0016] c) Sieve the small particles according to different particle sizes, and the small particles with a particle size of 0-2mm are qualified raw materials;

[0017] d) Take small particles with particle diameters other than 0-2 mm to return to the cage, and use a roller crusher to crush unqualified raw materials;

[0018] e) Sieve the small particles according to different particle sizes, and the small particles with a particle size of 0-2mm are qualified raw ...

Abstract

The invention discloses a compound bonding agent for a baking-free magnesium vibration material. The compound bonding agent is composed of the following components by mass percent: 86.35 wt% of anhydrous dextrose, 4.55 wt% of borax, 4.55 wt% of tropine and 4.55 wt% of industrial salt. The bonding agent is the non-toxic, tasteless and nuisanceless white crystalline particles or powder, has strong basicity, is easily dissolved in water, and is insoluble in alcohol and acid, the aqueous solution of the bonding agent is alkaline, and the bonding agent belongs to inorganic salt products. No elements polluting molten steel exist, no toxic or harmful gas is produced during heating the bonding agent, occupational safety and health of workers cannot be influenced, and no pollution to the environment is caused.

Description

technical field [0001] The invention relates to a compound binder used for baking-free magnesia vibrating material. Background technique [0002] At present, the binder of magnesium vibrating materials generally uses solid phenolic resin as raw material, which emits a large amount of toxic and harmful gases during baking and heating, pollutes the environment, is not conducive to clean steelmaking and environmental protection requirements, and brings health risks to construction workers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite binder for baking-free magnesia vibrating material, which meets the requirements of environmental protection and can also ensure the safety of construction personnel. [0004] In order to solve the above technical problems, the present invention adopts the following technical solution: a composite binder for baking-free magnesium vibrating material, the composite binder i...
