Preparation method and device of phosphorus-containing intrinsic flame-retardant polyacrylate composite material

Abstract

The invention belongs to the technical field of polyacrylate preparation, and particularly relates to a preparation method and device of a phosphorus-containing intrinsically flame-retardant polyacrylate composite material, and the phosphorus-containing intrinsically flame-retardant polyacrylate composite material comprises 75-90 parts of a phosphorus-containing intrinsically flame-retardant emulsion; 5-20 parts of a cross-linking agent; 2-10 parts of a liquid phosphate flame retardant; 4 to 20 parts of deionized water; 0.3 to 3 parts of a nonionic emulsifier; according to the method, the required phosphorus-containing intrinsic flame-retardant polyacrylate composite material can be obtained, the product not only has required adhesiveness, but also has a good flame-retardant effect, the product is uniform and fine, the stability is good, meanwhile, through a hydrodynamic cavitation stirring device, the stirring efficiency can be improved, the stirring effect can be guaranteed, and the flame-retardant effect is good. And meanwhile, the cavitation holes can be dredged, and the upper top surfaces of the spiral blades can be dredged, so that the influence on subsequent stirring is avoided.

Description

technical field [0001] The invention belongs to the technical field of acrylate preparation, in particular to a method for preparing a phosphorus-containing intrinsically flame-retardant polyacrylate composite material and a device thereof. Background technique [0002] Homopolymer or copolymer with acrylate as monomer. R and R' are substituents, different substituents have different polymer properties. Acrylate is very easy to polymerize under the action of light, heat and initiator, and polyacrylate is adhesive and can be used as pressure-sensitive adhesive and heat-sensitive adhesive. Because of its good aging resistance, less bonding pollution, and convenient use, its output increases rapidly. In the textile industry, polyacrylate can be used for sizing, printing and finishing. The textiles finished with it are crisp and beautiful, with good hand feeling; it can also be used as an adhesive for non-woven fabrics, flocking and flocking products. Polyacrylates can be use...

Problems solved by technology

The mass percentage of its composition is: 75%-90% of acrylic emulsion, 5%-20% of crosslinking agent, 1%-5% of organic phosphorus nitrogen flame retardant, and 1%-10% of solvent. When stirring and mixing, the stirring efficiency is low, the stirring quality is poor, and it is impossible to quickly and efficiently mix various reagents, thereby reducing the preparation effect

[0004] Chinese invention patent CN2019113448697 discloses a stirrer with hydraulic cavitation effect and its application. It relates to a stirring device and its application. It is to solve the technical problem of poor mixing effect of the existing stirrer. The stirrer includes a shell, Two brake plates, blades, stirring shaft, motor and controller; the shell is cylindrical; the two brake plates are arranged side by side on the same axial section of the shell with the axis of the shell as the symmetrical axis, and the two The disc brake plate is fixed on the top of the housing; the controller is connected with the motor; the stirring shaft is connected with the motor; the blade is fixed at the lower end of the stirring shaft, the stirring effect is poor, the homogeneous quality is poor, and the temperature of the emulsion in the device cannot be controlled Make adjustments to reduce the processing effect

[0005] At the same time, the cavitation holes of the existing hydraulic cavitation mixer are often blocked during actual use, thus losing

[0006] In addition, existing equipment and processes are also difficult to achieve uniform and stable in-situ polymerization / dispersion / compounding at the micro scale, and it is difficult to prepare intrinsically flame-retardant composites with stable quality
