Embodiment 1

[0027] 16% of polyvinyl chloride resin, 25% of aggregate powder (composed of talcum powder, magnesium powder, aluminum powder and kaolin powder), 15% of porosity agent (composed of calcite powder, aluminum oxide powder and baking soda powder ), 4% of organic foaming agent (composed of N, N'-dinitropentamethylenetetramine (commonly known as DPT), azodicarbonamide and azobisisobutyronitrile), respectively added to the mixer Stir to make it evenly mixed; then add 40% toluene to the mixture until it becomes a uniform fluid. Pour the mixed raw materials into the mold of the hydraulic press, and set the heating time and temperature according to the structure of the press and mold and the capacity of the inner cavity. The pressure value of the press is set at 18Mpa, the heating time is 55-65 minutes, and the temperature is 160-180°C. After the heating is completed, cool down until the mold is cold, then release the pressure and discharge the material. Then the molded material is se...

Abstract

The present invention relates to hard polyvinyl chloride plastic plate and its production process and material formulation. The plastic plate is produced through mixing pwodered material and organic solvent, molding in press through pressurizing, heating, maintaining, cooling and pressure relieving, and dischargin. The said powdered material consists of aggregate 18-30 wt%, polyvinyl chloride resin as binding material 15-28 wt%, oganic solvent 35-45 wt% and pore creating agent 12-25 wt%. The plate has the advantages of heat insulating, being fireproof, sound isolating, waterproof, non-toxic, etc. The improved formulation include great amount of aggregate and pore creating agent, and thus has reduced polyvinyl chloride resin consumption and low production cost.

Description

technical field [0001] The invention relates to a polyvinyl chloride plastic plate, in particular to a formula of a rigid polyvinyl chloride plastic plate. Background technique [0002] Rigid polyvinyl chloride plastic air ducts have been widely used in my country, but due to their poor performance in heat preservation, fire prevention, sound insulation, and secondary processing, and high manufacturing costs, they have been eliminated by the market. Later, flexible air ducts such as glass fiber and polyurethane were popularly used. Although these materials can play a certain role in heat insulation, there are still some shortcomings, such as fiber products that are troublesome in construction, easy to absorb water, and harmful to the human body. , Another example is that polyurethane foam materials have not yet reached the requirements for fire protection in many occasions. Contents of the invention [0003] The task of the present invention is to provide a formula of an ...
