Example Embodiment

[0034] Example 1: High flame retardant, low calorific value, smoke elimination and halogen free B 1 Preparation of core material for grade aluminum-plastic composite board

[0035] 1. Ingredients list

[0036] Table 1

[0037]

[0038] 2. Method

[0039] Put 108kg 800 mesh Mg(OH) 2 (Purity 94%), 3kg APP, 3kg zinc borate, 1.5kg aluminate coupling agent, 1kg silane coupling agent are put into a 300L high-speed mixer together, stir at high speed until the temperature rises to 105℃, then add 1.5kg solid wax, 1.5kg PE wax, 1.5kg palm wax, 1kg stearic zinc, 15kg EVA, 8kg POP and 5kg EAA, continue to stir at high speed until the temperature reaches 120°C before discharging.

[0040] When the above-mentioned processed materials are cooled to 40°C, they are then extruded and pelletized with a parallel twin-screw extruder at 135-150°C to obtain 150kg qualified products.

[0041] Example 2: High flame retardant, low calorific value, smoke elimination and halogen free B 1 Preparation of core material for grade aluminum-plastic composite board

[0042] 1. Ingredients list

[0043] Table 2

[0044]

[0045] 2. Method

[0046] 138kg 1250 mesh Mg(OH) 2 (Purity 92%), 2kg APP, 2kg titanate coupling agent, 1.5kg polymer coupling agent, 2.5kg PE wax, 2kg liquid paraffin, 1kg calcium stearate, 14kg EVA, 12kg POP and 5kg EAA together In a 110L internal mixer, plasticize for 12 minutes. When the temperature rises to 140°C and the material melts into a dough shape, the material can be discharged, and then the dough-like material is transferred into the conical single-screw extruder while it is hot. Extrusion granulation at ~150℃, 180kg qualified product can be obtained.

[0047] Example 3 Comparative test

[0048] The two kinds of high flame retardant low calorific value smoke elimination halogen-free B prepared in Example 1 and Example 3 1 The performance test of the core material of grade aluminum-plastic composite panel was carried out, and the performance of the core material of ordinary grade B aluminum-plastic composite panel was compared. The results are shown in Table 3 below.

[0049] Table 3 Invention B 1 Performance comparison of grade B aluminum-plastic composite panel core material and ordinary B-grade aluminum-plastic composite panel core material

[0050]

[0051] It can be seen from the results in Table 3 that, compared to the ordinary B-grade aluminum-plastic composite board core material, the high flame retardant, low calorific value, smoke elimination and halogen-free B 1 Grade aluminum-plastic composite panel core material has a higher oxygen index and a lower calorific value, indicating that the flame retardant effect of the presen...

Abstract

The invention discloses a high-inflaming-retarding and low-heating-value smoke-eliminating halogen-free B1-grade aluminum-plastic compounding panel core material and a preparing method thereof. The aluminum-plastic compounding panel core material comprises fire retardant, surfactant, processing agent and resin. Preferentially, according to the high-inflaming-retarding and low-heating-value smoke-eliminating halogen-free B1-grade aluminum-plastic compounding panel core material and the preparing method thereof, a compound compounded through any one or two or more of natural Mg(OH)2, zinc borate and ammonium polyphosphate is selected as the fire retardant, the resin is selected from an ethylene-vinyl acetate copolymer (EVA), polyolefin plastomer (POP), ethylene-ethyl acrylate (EEA), an ethylene-acrylic copolymer (EAA), the polarity of the oxygenic resin is larger than that of PE, PP and the like, the oxygenic resin is more prone to combing with Mg(OH)2, APP and zinc borate. An experiment shows that compared with a common B-grade aluminum-plastic compounding panel core material, the aluminum-plastic compounding panel core material prepared with the method has the good oxygen index and the low heat value and is good in inflaming retarding effect; in addition, the aluminum-plastic compounding panel core material is good in comprehensive mechanical performance and aluminium-plate affinity and high in product peeling strength.

Description

technical field [0001] The invention relates to a flame-retardant plastic building material, in particular to a high flame-retardant low calorific value smoke-eliminating and halogen-free B 1 The invention relates to a core material of a grade aluminum-plastic composite board, and also relates to a preparation method and application of the core material. Background technique [0002] Plastic has the advantages of light weight, easy processing, and convenient construction. It is widely used in building materials, especially aluminum-plastic composite panels, which are indispensable decorative materials in high-end buildings. Since plastics are mainly composed of hydrocarbons and are extremely flammable, most of the fires are caused by plastic products. Therefore, solving the problem of plastic flame retardancy is an important issue in plastic building materials and plastic electrical appliances. Aluminum-plastic composite panels are the main products in plastic building mate...
