Embodiment 1

[0016] a. First, mix the raw materials of each layer of the board above evenly in their respective mixing hoppers, and at the same time, carry out drying treatment at a temperature of 65°C for 5 hours, and set the temperature of one of the extruders at 200- In the range of 260°C, the raw materials are calculated by weight percentage, 0.1% UV, and the balance is the ratio of PMMA. After melting and plasticizing, they are extruded into the distributor as an acrylic layer, and the temperature of the second extruder body is set Set in the range of 200-240°C, the raw materials are calculated by weight percentage, 0.2% UV and 5% titanium dioxide blue masterbatch, and the rest is the ratio of ABS, melted and plasticized, then extruded into the dispenser as a cloud background layer; set the body temperature of the third extruder to 200-240°C, set the extruder motor speed and change speed time period to 1 stage: 15 seconds / 900 revolutions, 2 stages: 40 seconds / 1000 revolutions, Stage 3...

Abstract

The invention discloses an extruded acryl composite cloudy-color plate and a manufacturing method thereof. A color layer of the extruded acryl composite cloudy-color plate is formed by the coextrusion of a cloudy-color layer and a cloud background layer, the cloudy-color layer and the cloud background layer are both made of ABS, UV and titanium dioxide-color master batches, a base layer of the plate is made of ABS and titanium dioxide-color master batches, and an acryl layer is made of UV and PMMA. The raw materials are dried, simultaneously extruded into a dispatcher by four plastic extruders, extruded out by a T-shaped die head, and rolled to form the extruded acryl composite cloudy-color plate. The thickness of the extruded acryl composite cloudy-color plate can be controlled within 0.8-10 mm. The extruded acryl composite cloudy-color plate has the characteristics of wide application, low density, good surface finish, high flexibility, favorable subsequent processability, stable color and pattern and the like. Compared with production by the traditional secondary casting method, the production efficiency and the mechanization degree of products are improved.

Description

technical field [0001] The invention relates to an extruded acrylic composite cloud plate and a preparation method thereof, in particular to a method for preparing an extruded acrylic composite cloud plate suitable for making sanitary ware and decorative materials by adopting a co-extrusion method. Background technique [0002] Acrylic composite cloud board is widely used in decoration, handicraft products and various sanitary ware and other fields, and is deeply loved and welcomed by people. The preparation of traditional acrylic composite cloud panels is generally made by casting, but due to its complicated production process and low output, it cannot be mass-produced and professionally produced. At the same time, in terms of performance, its impact strength It is not ideal enough, which limits its scope of application to a certain extent. Contents of the invention [0003] One of the objectives of the present invention is to provide an extruded acrylic composite cloud ...
