Embodiment 1

[0032] Follow the steps below to manufacture PVC composites for decorative panels:

[0033] (1) Wash and dry the mangosteen shell, crush it with a pulverizer and sieve it to obtain a mangosteen shell powder with a particle size of 1mm, add the mangosteen shell powder into a dilute hydrochloric acid solution with a mass fraction of 8%, and mix the mangosteen shell powder with The weight ratio of the dilute hydrochloric acid solution is 1:10, heat it to 100°C and keep it warm for 2 hours, take it out, wash it with distilled water to neutrality, and obtain acidified mangosteen shell powder after drying;

[0034] (2) adding the acidified mangosteen shell powder obtained by step (1) into the potassium permanganate solution with a mass fraction of 2%, the quality of the potassium permanganate solution is half of the acidified mangosteen shell powder, heated to 80°C and stirred for 3 After standing for 3 hours, vacuum filter, take it out, wash it with distilled water until neutral, d...

Abstract

The invention provides a PVC composite material for a decorative plate and a manufacturing method of the material. The method mainly includes the following steps that firstly, mangosteen shells are cleaned, dried, smashed and screened to obtain mangosteen shell powder, and the mangosteen shell powder is processed by a diluted hydrochloric acid solution to obtain acidified mangosteen shell powder; secondly, the acidified mangosteen shell powder is processed by a potassium permanganate solution to obtain modified mangosteen shell powder; thirdly, europium oxide reacts with nitric acid to prepare an europium nitrate solution, and the europium nitrate solution, a urea solution, sodium dodecyl benzene sulfonate and the modified mangosteen shell powder are mixed, stirred, filtered, washed, dried, roasted and ball-milled to obtain composite powder; fourthly, PVC, the composite powder and other auxiliaries are mixed, melted, extruded, subjected to water cooling, granulated and dried, and the PVC composite material for the decorative plate is obtained. The manufactured PVC composite material for the decorative plate has high yellowing resistance.

Description

[0001] Technical field: [0002] The invention relates to a composite material, in particular to a PVC composite material for a decorative board and a manufacturing method thereof. [0003] Background technique: [0004] Decorative panels can be divided into two categories: solid wood panels and wood-based panels. At present, except for floors and door leaves that use solid wood panels, the panels generally used by people are artificially processed wood-based panels, which usually have high durability. Wear resistance, heat resistance, cold resistance, fire prevention and other good physical properties, widely used in walls, roofs, cabinets, cupboards, tables, beds, precision instrument workbenches, laboratory test benches, TV sets, radios and other broadcasting and telecommunications equipment shell and so on. Decorative panels can be divided into solid panels, plywood, fiberboards, decorative panels, fireproof panels and so on. [0005] One of the major types of wood-based ...
