Abstract

The invention provides a composite raw material particle for preparing a sludge-based building template. The composite raw material particle is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride, 10-30 parts of polypropylene, 60-100 parts of sludge of 600-3000 meshes, 2-5 parts of titanium dioxide rutile, 0.5-1 part of halloysite, 0.2-0.5 part of acicularwollastonite, 10-20 parts of epoxy soybean oil, 2-8 parts of a calcium zinc stabilizer, 1-3 parts of an impact modifier, 4-10 parts of chlorinated paraffin, 0.8-1.6 parts of stearic acid, 2-5 parts of aluminic ester, 1-2 parts of an antioxidant, 0.5-2 parts of an anti-UV absorber and 0.5-2 parts of paraffin. The composite raw material particle has the advantages that the mechanical properties, tensile strength, elastic modulus, impact resistance, aging resistance and thermal properties of inorganic fillers and PVC-based composite materials are improved and the service life is prolonged.

Description

technical field [0001] The invention relates to the material preparation and application fields of sludge resource utilization, inorganic powder modification and composite processing with organic carriers produced by urban sewage treatment plants, and specifically relates to a new type of sludge that uses sludge as the main filler for the preparation of Composite raw material particles for sludge-based polyvinyl chloride building templates and a preparation method thereof. Background technique [0002] As far as the traditional plastic industry is concerned, based on its material properties and sources, there are the following limitations or disadvantages in application, which are specifically reflected in: First, in view of the fact that traditional plastics are difficult to degrade, the "white pollution" produced by them poses a threat to the ecological environment. The environment has brought immeasurable negative impacts. Secondly, because the source material of organic...
