Abstract

The invention discloses an alkali-free concrete accelerator and a processing method thereof. The alkali-free concrete accelerator comprises the following raw materials in parts by weight: 30-65 partsof aluminum sulfate, 2-8 parts of an organic amine, 1-3% of a stabilizer, 1-5 parts of a suspending agent, 20-35 parts of water, 2-5 parts of bentonite and 4-6% of magnesium fluosilicate. In the present invention, the caulking agent for building decoration of prefabricated parts is simple in preparation method, low in cost, is liquid after preparation, can be uniformly mixed with concrete conveniently, contains no alkali or chlorine or pungent smell, is high in safety, is harmless to human body, is excellent in cohesiveness; adding of a stabilizing agent can prolong the storage time, preventdeterioration; magnesium fluosilicate and aluminum sulfate are adopted for cooperative using, so that the resilience value is low, later strength retention rate is high, and impermeability grade is high; adding of the alkali-free concrete accelerator in sprayed concrete is capable of achieving a preferable working environment and considerable market value.

Description

technical field [0001] The invention relates to the technical field of concrete quick-setting agents, in particular to an alkali-free concrete quick-setting agent and a processing method thereof. Background technique [0002] The caulking agent is a kind of gray powder prepared from polymer materials and base materials. It is mainly used for hooking and inlaying various stone joints such as glazed tiles, marble, and granite. [0003] At present, the caulking agents used in the market are monotonous in color, mostly gray or white, and their decoration is poor. The existing caulking agents have poor cohesive force, and the joints are easy to open. , aging resistance, and cracks are prone to appear in the clamp channel, so it cannot meet the needs of users. Contents of the invention [0004] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, and propose a kind of alkali-free concrete quick-setting agent and preparation met...
