Problems solved by technology

In order to pursue higher flame retardant efficiency, nano-scale powders with smaller particle sizes have been developed, but nano-scale flame retardants have two main problems that are more serious than general powder additives: easy to agglomerate and large dust in the processing environment
However, its selection range is limited, and it is only composed of phosphazene compounds and phosphate compounds; and only by adhesion, its fixing effect is limited, and it is not easy to store and transport
In addition, some fiber substances are not necessary for the resin system, which can easily bring about negative effects
While compounded powdered substances are easier to manipulate and apply than liquids and sticky solids, persistence and uniformity issues remain

Embodiment 1

[0044] Example 1 : Weigh 30g polystyrene open-pore particles (EPS, diameter 3mm, porosity 60%) in a 1000 ml beaker, then add 30g liquid flame retardant tris(β-chloroethyl)phosphate (TCEP) Among them, mechanical stirring at a speed of 20 rpm at room temperature for 30 minutes, so that the liquid flame retardant TCEP is completely adsorbed into the polystyrene open-pore particles, and the surface of the particles is dry, and a flame-retardant adsorption masterbatch with a concentration of 50% is obtained.

Embodiment 2

[0045] Example 2 : Weigh 70g of polyurethane open-cell particles (EPU, diameter 3mm, porosity 60%) in a 1000ml beaker, then add 30g of liquid flame retardant tris(β-chloropropyl)phosphate (TCPP), Mechanically stirring at 60 rpm for 20 min at 40°C, the liquid flame retardant TCPP was completely adsorbed into the polyurethane open-pore particles, and the surface of the particles was dry, and a flame-retardant adsorption masterbatch with a concentration of 30% was prepared.

Embodiment 3

[0046] Example 3: Weigh 1g of open-cell polypropylene particles (EPP, particle size 4mm×3mm, porosity 80%) in a 1000ml beaker, and then add 99g of liquid flame retardant tetraphenylresorcinol diphosphate (RDP) Add it in, and stir mechanically at 30 rpm for 10 min at 90°C. The liquid flame retardant RDP is completely absorbed into the adsorption material, and the surface of the particles is slightly dry, and a flame retardant adsorption masterbatch with a concentration of 99% is prepared.

Abstract

The invention discloses a flame retardant adsorption master batch and a preparation method thereof. The flame retardant adsorption master batch is prepared by mixing and absorbing 1-7 parts of a porous adsorbing material particle and 99-30 parts of a flame retardant additive, wherein the porous adsorbing material particle is a polyolefin open-cell foamed plastic or natural porous material with a partial open-cell structure or sponge or netty microstructure; the average particle size of the porous adsorbing material particle is 1-10 mm, the porosity is at least 30% and the average diameter of the micropore is 50-200 mu m. The porous adsorbing material particle is taken as a storage stack for absorbing a liquid or suspending flame retardant, wherein the maximum concentration is 99%; in the high polymer material machining process, the adding amount of the master batch is few, the operation is convenient and the physical and mechanical properties influence on the resin material is small; the traditional master batch preparation process can be replaced without an expensive device or heating treatment, so that the master batch preparation period and device utilization rate are greatly shortened.

Description

technical field [0001] The invention belongs to the field of organic polymer materials, and in particular relates to a novel flame-retardant adsorption masterbatch and a preparation method thereof. technical background [0002] Polymer materials plastics, rubber, and fibers have occupied every aspect of people's daily life, and they are widely used in many fields such as walls, ceilings, furniture, floor coatings, fabrics, electronics, vehicles, and electrical appliances. However, as hydrocarbon polymer materials derived from petroleum, most of them are flammable, and some of them are flammable. In recent years, with the wide application of polymer materials, fires have become more and more frequent. According to the statistics of the International Fire Protection Technical Committee, tens of thousands of people die due to fire every year, and the property loss directly or indirectly caused by fire is about 1-2.5% of the global gross national product. [0003] At present...
