Embodiment approach 1

[0037] 1. High speed kneading:

[0038] The various raw material formulations that make up the polishing slag-modified PE flame-retardant foamed silicon-plastic plate were weighed according to the following parts by mass, and set aside.

[0039]

[0040] Put the LDPE resin into the high-speed mixer, then add the rest of the raw materials, and stir for 3 minutes at high speed; discharge the material into the cold mixer, stir for another 5 minutes, and discharge the material after cooling to obtain a polished slag modified PE flame-retardant foam Silicon plastic plate compound.

[0041] 2. Extruded sheet:

[0042] Put the mixture into the twin-screw extruder. The temperature of each zone of the extruder is: zone 1 / 110°C, zone 2 / 130°C, zone 3 / 140°C, zone 4 / 150°C, and head / 155°C. The extruder extrudes the film through the head die to prepare the polishing slag modified PE flame-retardant foamed silicon-plastic sheet.

Abstract

The invention discloses a polishing slag modified PE flame-retardant foamed silicon-plastic plate and a preparation method, wherein the polishing slag modified PE flame-retardant foamed silicon-plastic plate is prepared by taking stone, ceramic tiles and artificial stone polishing slag as flame-retardant fillers through the steps of high-speed kneading, sheet extrusion, blank pre-foaming, hot-pressing foaming, cooling shaping, cutting trimming and the like. Research finds that the polishing slag is a composite flame retardant with multiple flame retardant mechanisms, replaces calcium carbonateas an inorganic filler flame retardant and is filled in a large amount of PE flame-retardant foamed silicon-plastic plates, and the problems that in the prior art, PE plastic is inflammable, a largeamount of high-price flame retardants need to be added to prepare flame-retardant plates, and the production cost is high are solved. Not only can the production cost be reduced, but also the problemsthat stone, ceramic tiles and artificial stone polishing residues are difficult to recycle and environmental pollution is caused by waste landfill can be solved, and waste is turned into resources.

Description

technical field [0001] The invention relates to the technical field of decorative materials, and mainly relates to a PE flame-retardant foamed silicon plastic plate modified by polishing slag and a preparation method thereof. Background technique [0002] Polyethylene PE plastic has good thermal stability, odorless, tasteless, and non-toxic. It is the polymer with the simplest structure. It is composed of repeated -CH2- units. Carbon and hydrogen are two elements that will not cause any impact on the human body and the environment. PE foamed calcium-plastic board has both the processing of wood and the secondary processing of thermoplastics. It has light weight, good heat insulation, sound insulation, corrosion resistance and excellent electrical insulation. It can replace wood and be processed into ceilings, partition boards, etc. Decoration Materials. However, HDPE plastic is flammable, its oxygen index is only 17.4, and it has burning drop phenomenon. After adding a lar...
