Problems solved by technology

[0004] However, products made of such traditional brominated flame retardant masterbatches produce many toxic substances when burned, among which polybrominated dibenzodioxane (DBDO) and polybrominated dibenzofuran (DBDF) not only It affects the normal metabolism of the human body and is carcinogenic. The International Center for Cancer Research has listed it as a first-class human carcinogen
This kind of flame retardant products not only has a high concent...

specific Embodiment approach 1

[0020] Such as figure 1 As mentioned above, the preparation method of a compound flame retardant masterbatch of the present invention is carried out based on a compound flame retardant masterbatch of the present invention, and the composition and content of the compound flame retardant masterbatch are as follows in parts by mass: 100 parts of carrier resin; 100 to 200 parts of compound flame retardant; 3 to 5 parts of lubricating dispersant; 2 to 3 parts of antioxidant, the preparation method of which is as follows: figure 1 , the specific method steps are as follows:

[0021] Implement the preparation method of a kind of composite flame retardant masterbatch of the present invention to carry out according to the following steps:

[0022] Step 1. Dry the carrier resin at 80-120° C. for 2 h to control the water content below 0.03% (mass percentage), and obtain the dried carrier resin for future use.

[0023] Step 2: Composite and surface treatment the compound flame retarda...

Embodiment 1

[0034] According to the above preparation method: the composition and content of the raw materials of the composite flame retardant masterbatch used in the present invention are: 100g low density polyethylene resin; 200g composite flame retardant; 5g polyethylene wax 420P; 2g antioxidant 1010 . Among them, the composition and content of the compound flame retardant masterbatch are: 120g of decabromodiphenylethane; 20g of antimony trioxide; 40g of zinc borate; 20g of linear thermoplastic phenolic resin powder; use 3g of silane coupling agent KH-570, The prepared compound flame retardant masterbatch.

[0035] The flame retardant masterbatch is used for flame retardant modification of polyethylene, adding 50%, passed the horizontal and vertical combustion test, has outstanding flame retardant effect, and reached the V-0 level requirement of UL-94 standard.

Embodiment 2

[0037] The difference between this example and Example 1 is that the carrier resin in the proportion of the compound flame retardant raw material masterbatch is 100 g of polypropylene resin, and the rest are the same to prepare the compound flame retardant raw material masterbatch.

[0038] The masterbatch is used for flame retardant modification of polypropylene, adding 45%, it has passed the horizontal and vertical combustion test, and has a significant flame retardant effect, and can also meet the V-0 requirements of the UL-94 standard.

Abstract

The invention provides a compound inflaming retarding masterbatch and a preparation method of the compound inflaming retarding masterbatch. The inflaming retarding masterbatch is formed by mixing carrier resin, a compound fire retardant, a lubrication dispersing agent and antioxygen. The method comprises the following steps of: mixing 1,2-Bis(2,3,4,5,6-pentabromophenyl)ethane, antimonous oxide, zinc borate, linear thermoplastic phenolic resin powder, adding a silane coupling agent for mixing to obtain the compound fire retardant; adding the dried carrier resin, the compound fire retardant, the lubrication dispersing agent and the antioxygen in a high-speed mixer for mixing, extruding, prilling and drying to prepare the compound inflaming retarding masterbatch. The diphenylethane decabromide serves as a main fire retardant which contains halogen and does not contain toxin, no poisonous polybrominated dibenzodioxins or polybrominated dibenzofurans are produced during burning, and simultaneously low-price zinc borate partially replaces expensive antimonous oxide, so that the compound inflaming retarding masterbatch has price superiorities, effectively reduces density of smoke obtained during burning simultaneously and restrains drop caused by burning and fusing. Synergistic effects of a compound inflaming retarding system greatly improve inflaming retarding efficiency of the compound inflaming retarding masterbatch.

Description

technical field [0001] The invention relates to a flame-retardant masterbatch and a preparation method thereof, in particular to a compound flame-retardant masterbatch used for plastic addition in the field of polymer materials and a preparation method thereof. Background technique [0002] Flame retardant plastics are modified by adding flame retardants to plastics to improve the performance of flame retardant and fire prevention. However, plastic flame retardants are mostly powder, and the dust will fly during processing, and the operating environment is extremely poor. Moreover, the volume difference between the powder and the granular plastic base material is large, and the density difference is very different, so it is difficult to mix evenly. In addition, extruders and injection molding machines have limited mixing properties along the axis of the material, and equipment vibrations make the powder easily sink and cause the separation of resin pellets, resulting in segr...
