Problems solved by technology

[0005] As a new type of material for making ceiling panels, stone-plastic materials have gradually entered the public's field of vision, but the existing ceiling panels made of stone-plastic materials have low rigidity and high brittleness during use, and are prone to cracks over time. The use experience is reduced, which is not conducive to the promotion and application of the above-mentioned ceiling panels in the market

Embodiment 1

[0018] Embodiment 1: Stone-plastic composite material ceiling board, stone-plastic composite material includes stone powder and plastic powder, and is made of the raw material of following weight ratio content: The ratio of stone powder and plastic powder is 3:10, and the density of stone powder is 3.55 g / cm 3 , the main raw material of the stone powder is natural gypsum containing calcium sulfate, the main raw material of the plastic powder is polyethylene, and a powdered natural fiber material is added to the composite material after the above stone powder and plastic powder are mixed, and the natural fiber material is Powdered wood chips are used for mixing with stone-plastic powder, and the amount of water is increased proportionally, so that the rigidity of the stone-plastic composite board itself is increased and the brittleness is reduced.

Embodiment 2

[0019] Example 2: The difference between this example and Example 1 is that the weight ratio of stone powder to plastic powder is 1:2, and the density of stone powder is 4.67g / cm 3 , the main raw material of the stone powder is phosphogypsum containing calcium sulfate, the main raw material of the plastic powder is polypropylene, and a powdered natural fiber material is added to the composite material after the above stone powder and plastic powder are mixed, and the natural fiber material is Powdered bamboo chips are mixed with stone-plastic powder, and the amount of water is increased proportionally, so that the rigidity of the stone-plastic composite board itself is increased and the brittleness is reduced.

Embodiment 3

[0020] Example 3: The difference between this example and Example 1 is that the weight ratio of stone powder to plastic powder is 1:3, and the density of stone powder is 3.68g / cm 3 The main raw material of stone powder is a mixture of calcium sulfate-containing phosphogypsum and fluorogypsum, the main raw material of plastic powder is a mixture of polyethylene and polypropylene, and the natural fiber material is powdered rice husk. The rigidity of the finished stone-plastic composite board increases and the brittleness decreases.

Abstract

The invention relates to a stone-plastic composite material and a stone-plastic composite material ceiling plate. The stone-plastic composite material comprises stone powder and molding powder which are prepared from the follwoing raw materails in parts by weight, wherein the weight ratio of the stone powder to the molding powder is 3: 10-1: 2, the density of the stone powder is 3.55-4.67 g/cm < 3>, and a powdery natural fiber material is added into the composite material obtained after the stone powder and the molding powder are mixed. The stone-plastic composite material comprises stone powder and molding powder, the stone powder and the molding powder are mixed in proportion, and the powdery natural fiber material is added into the mixed stone powder and molding powder so that the rigidity of the manufactured ceiling plate can be improved, the brittleness is reduced, the probability of deflection deformation of the ceiling plate is reduced to a great extent, and thus the probability that the ceiling plate generates adverse consequences such as cracks is reduced, and popularization and application of the ceiling plate in the market are facilitated.

Description

technical field [0001] The invention relates to the technical field of decoration and decoration, in particular to a stone-plastic composite material and a stone-plastic composite material ceiling board. Background technique [0002] Suspended ceiling refers to a kind of decoration on the top decoration of the living environment of the house. Simply put, it refers to the decoration of the ceiling and is one of the important parts of interior decoration. [0003] The suspended ceiling has the functions of heat preservation, heat insulation, sound insulation and sound absorption, and it is also the hidden layer of electrical, ventilation and air conditioning, communication and fire protection, alarm pipeline equipment and other projects. [0004] Home decoration ceiling is a common link in home decoration. The classification of the ceiling is different according to the material of the decorative board. The ceiling decoration material is the main basis for distinguishing the na...
