Embodiment 1

[0031] 3kg corn starch, 4.5kg flame retardant magnesium hydroxide, 0.9kg flame retardant synergist montmorillonite, 1.2kg composite plasticizer (glycerin: sorbitol = 1:1), carrier resin polyadipate-p Butylene phthalate (PBAT) 1.2kg was sequentially added to the high mixer and mixed for 7 minutes, then 50g of the mixture was weighed and added to a mixer at 140°C for 5 minutes, and the speed of the mixer was 30rpm. Granulator granulation to obtain starch flame retardant masterbatch.

Embodiment 2

[0033] Add 3kg of potato starch, 4kg of flame retardant aluminum hydroxide, 0.8kg of flame retardant synergist antimony trioxide, 1.2kg of composite plasticizer (glycerol: sorbitol = 1:1), and 1.2kg of carrier resin PBAT to the Mix in a high-mixer for 7 minutes, then weigh 100 g of the mixture and add it to an open mill at 140 ° C for 5 minutes and mix for 5 minutes. The speed of the open mill is 20 rpm, and finally granulate through a granulator to obtain a starch flame retardant masterbatch.

Embodiment 3

[0035] Add 3kg of cornstarch, 3.5kg of flame retardant ammonium polyphosphate, 0.7kg of flame retardant synergist brucite, 1.2kg of composite plasticizer (urea: formamide = 1:1), and 1.2kg of carrier resin PBAT to the Mix in a high mixer for 7 minutes, then add to an extruder for blending and extrusion, the extrusion temperature is 140°C, the screw speed is 250rpm, and finally granulated by a granulator to obtain a starch flame retardant masterbatch.

Abstract

The present invention relates to a fire retardation master batch, particularly to a starch fire retardation master batch and a preparation method thereof. The starch fire retardation master batch is prepared from the following components, by weight: 20-50 parts of starch, 5-20 parts of a plasticizer, 20-60 parts of a fire retardation agent, 5-15 parts of a fire retardation synergist, and 5-20 parts of a carrier resin. Compared with the starch fire retardation master batch in the prior art, the starch fire retardation master batch of the present invention has the following characteristics that: the starch fire retardation master batch can be directly added to a biodegradable material and can endow the biodegradable material with fire retardation so as to substantially expand a use range of the biodegradable material.

Description

technical field [0001] The invention relates to a flame retardant masterbatch, in particular to a starch flame retardant masterbatch and a preparation method thereof. Background technique [0002] Plastic has become an indispensable material in industrial production and people's life. At the same time, with the extensive application of petrochemical plastics, waste plastic products are also increasing day by day. Since most of today's general-purpose plastics are stable in performance, they are not easy to be rapidly degraded by various environmental factors in nature, so the so-called "white pollution" appears. At present, there are many ways to deal with "white garbage", such as incineration and landfill, but when waste plastics are incinerated, they will cause serious secondary pollution to the environment. Therefore, green, environmentally friendly degradable materials are in urgent need of us. [0003] Degradable plastics, especially biodegradable plastics, are a hot...
