Problems solved by technology

Since polyvinyl chloride materials are required to have good rigidity in the fields of construction and home decoration, less plasticizers are usually added. However, practice has proved that less plasticizers will not only make the polyvinyl chloride material hard, but also cause deterioration at low temperature. brittle problem
Conversely, if the amount of plasticizer added is increased, it will help to overcome the brittleness at low temperature, but it will seriously affect the rigidity of PVC materials
Therefore, the applicant believes that if attention is paid to the reasonable choice of the amount of plasticizer, it will be difficult to meet the rigidity requirements of the aforementioned construction and home improvement fields for PVC materials, that is to say, it is impossible to find a reasonable balance between rigidity and low-temperature brittleness. balance point
[0003] The above-mentioned technical problems have plagued the industry for a long time and are expected to be solved, but there is no corresponding technical revelation in the patents and non-patent literature published so far

Description

technical field [0001] The invention belongs to the technical field of polymer material preparation, and in particular relates to a method for preparing a rigid polyvinyl chloride composite material toughened by an acrylonitrile-butadiene-styrene copolymer. Background technique [0002] Polyvinyl chloride is a basic resin with excellent performance, which is widely used in construction, automobile, home improvement, decoration and other fields. Since polyvinyl chloride materials are required to have good rigidity in the fields of construction and home decoration, less plasticizers are usually added. However, practice has proved that less plasticizers will not only make the polyvinyl chloride material hard, but also cause deterioration at low temperature. Fragility problem. Conversely, if the amount of plasticizer added is increased, it will help to overcome the brittleness at low temperature, but it will seriously affect the rigidity of the PVC material.
