Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of water-based carpet glue and its production method, to solve the problem that the prior art adopts the batch method of production, all the monomers are added in the reaction kettle, and the initiator is slowly added dropwise. This method is very easy to cause detonation. If the kettle is flushed, it will cause an explosion if it is serious; there are problems such as unsafe transportation and the generation of toxic gas during use

Abstract

The invention provides an aqueous carpet adhesive and a production method, and belongs to the technical field of fine chemistry. According to the aqueous carpet adhesive, a solvent is replaced by water used for replacing toluene which is an organic solvent quite toxic to a human body and severe in environmental pollution, emulsifying agents are used, and a step-by-step charging method is adopted. Raw material components of the aqueous carpet adhesive comprises deionized water, the emulsifying agents, cross-linking agents, initiating agents, acrylate monomers, deodorant, function monometers and neutralizing agents. The preparation method processing steps comprise a step (1) of pre-emulsification, a step (2) of washing, a step (3) of warming, a step (4) of titration, a step (5) of deodorization and a step (6) of potential of hydrogen (PH) adjustment. Cooling is carried out after the deodorization is finished, the PH adjustment is carried out through addition of the neutralizing agents, filtration and discharging are carried out, and carpet adhesive products are achieved. The aqueous carpet adhesive and the production method can greatly reduce product cost due to the fact that the water is used as a solvent, a great deal of invested capital needed by waste gas treatment is eliminated, reaction kettle collision and potential safety hazard caused by implosion are avoided, the problem of poisonous gas generation in a using process is solved, and transportation safety of products is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to an environment-friendly carpet glue. Background technique [0002] The survey by the national authoritative organization found that the main sources of indoor air pollution in new buildings are interior decoration materials and furniture. Most of them contain organic volatiles such as formaldehyde and benzene. Formaldehyde is an important organic raw material. It is colorless and strongly irritating. The gas has been identified as a carcinogenic and teratogenic substance by the World Health Organization, and the original carpet glue is a solvent type containing a large amount of solvent formaldehyde. It is widely used in offices, housing and public facilities, which endangers human health and is easy Combustible and explosive have brought great potential safety hazards to production and transportation, and also pose a threat to people's personal and property. ...
