Abstract

The invention belongs to the technical field of PP plates, and particularly relates to a flame-retardant PP plate and a preparation method thereof. The flame-retardant PP plate comprises the followingraw materials by mass: 83-85% of a PP material; 9-11% of a flame retardant; 1.5-4% of a toughening agent; 0.1-0.3% of a main antioxidant; 0.1-0.3% of a secondary antioxidant; 0.1-0.3% of an ultraviolet absorber; 0.05-0.15% of diffusion oil; and 1-3% of color masterbatch. The preparation method of the flame-retardant PP plate comprises the following steps: 1) stirring the raw materials, and 2) carrying out high-temperature extrusion molding. The flame-retardant PP plate has the advantages of good flame retardancy, good weather resistance, good toughness, good mechanical properties, long service lifetime and good ultraviolet resistance, and can meet the requirements of outdoor use.

Description

technical field [0001] The invention belongs to the technical field of PP boards, and in particular relates to a flame-retardant PP board and a preparation method thereof. Background technique [0002] Polypropylene, referred to as PP, is a colorless, odorless, non-toxic, translucent solid substance. The density of PP is 0.89~0.91g / cm 3 , flammable, with a melting point of 165°C, softens at around 155°C, and a service temperature range of -30 to 140°C. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, conveying pipes, plates, chemical containers, etc., and is also used in food and drug packaging. [0003] Disadvantages of PP materials: flammable, easy to age, become brittle, and easy to deform after demoulding; resulting in poor flame retardancy, aging resistance, and weather resistance of PP sheets made of PP materials, which are not suitable for outdoor use and limit the Applic...
