Problems solved by technology

Traditionally, most common flame retardants for polymers are solid powder or granules, and solid flame retardants have low environmental protection level and high cost; for liquid flame retardants, especially halogen-free flame retardants, such as tetraphenyl (Bisphenol-A) diphosphate (BDP) and tetraphenylresorcinol diphosphate (RDP) can meet the requirements of environmental protection, but generally have a relatively high viscosity, and special equipment such as liquid quantitative pressure pumps are required for use. It can be mixed with the polymer, and the cost of these equipment is very high, which seriously limits the popularization and use of liquid flame retardants

Embodiment Construction

[0012] like figure 1 Shown is the flow chart of the method of using the liquid flame retardant, and the specific steps are as follows:

[0013] S110: put auxiliary materials.

[0014] S120: heating and stirring to mix the auxiliary materials evenly.

[0015] Put a certain volume of PC (Polycarbonate, polycarbonate), ABS (Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene copolymer) and other auxiliary materials into the heating stirrer, and stir and heat, if the temperature is too high , PC and ABS will volatilize and decompose, and waste electric energy at the same time; the temperature is too low, the mixing efficiency is not high, and the mixing time is long. Generally, the heating and stirring temperature is within 50-100 ° C. At this time, PC, ABS, etc. can be well mixed.

[0016] S130: add liquid flame retardant.

[0017] The liquid flame retardants used here are halogen-free liquid flame retardants, mainly condensed non-halogen organic phosphorus flame ...

Abstract

The invention relates to a using method of a liquid flame retardant. The use method comprises the following steps: putting auxiliary materials in a container; heating and stirring the auxiliary materials to mix the auxiliary materials uniformly; adding the liquid flame retardant into the auxiliary materials; continuing to heat and stir the mixture to fully mix the liquid flame retardant with the auxiliary materials; and discharging the obtained material. The heating and stirring method is adopted to fully mix the liquid flame retardant with the auxiliary materials such as PC, ABS and the likein place of expensive special equipment for the liquid flame retardant such as metering pressure pump, so that the cost is effectively saved, the production efficiency is improved, and the effects ofenvironment protection and fire resistance are excellent.

Description

【Technical field】 [0001] The invention relates to a method for using a liquid flame retardant. 【Background technique】 [0002] Polymers such as plastics, elastomers and thermosets are used in numerous applications such as walls, ceilings, furniture, floor coatings, fabrics, electronics, vehicles and appliances. Since most polymers are combustible, fire safety is extremely important in every application, and the fire safety of polymers can generally be improved by adding flame retardants to polymers. Flame retardants consist of compounds that are added to materials to increase their fire and heat resistance or ability to resist flames. Traditionally, most common flame retardants for polymers are solid powder or granules, and solid flame retardants have low environmental protection level and high cost; for liquid flame retardants, especially halogen-free flame retardants, such as tetraphenyl (Bisphenol-A) diphosphate (BDP) and tetraphenylresorcinol diphosphate (RDP) can meet...
