Abstract
The present invention provides a light thermal insulating material made from abandoned polyphenyl foam and a method thereof. Polystyrene foam plastics is pulverized into particles with the diameter smaller than 3 millimeters, and 1g of cement, 5g of benzene, 0.3g of OP-20 and 1.9g of water are added; the particles, the cement, the benzene, the OP-20 and the water after being uniformly mixed are injected into a mould, formed, cured and matured for 72 hours to obtain the product of the present invention. The present invention regenerating and utilizing the polystyrene foam plastics has the advantages of white pollution elimination and production cost reduction. The lambda of the product of the present invention is less than 0.1 W/m. k, the compressive strength is higher than 1.5mpa, and the volume weight is lower than kg/m<3>. The product of the present invention can be made into building prefabricated elements, such as thermal insulating bricks (boards), hollow wall bricks (boards), etc.
Description
The present invention relates to utilize waste or used plastics to produce the method for material of construction, exactly provide a kind of light heat insulation material and method made from waste polystyrene foamed plastics, belong to the building materials production technical field.
Existing polystyrene foamed plastics product degradation rate is very low, and volume is big, in light weight, difficulty is reclaimed in transportation, uses existing technology, can not regeneration, and cause serious environmental to pollute and the wasting of resources.
The invention provides a kind of light heat insulation material and method made from waste polystyrene foamed plastics, produce the heat preservation construction material of light weight, solved polystyrene foamed plastics regeneration problem.
Light heat insulation material of the present invention by the following raw materials in parts by weight number than making:
1 part of cement, 2～10 parts of polystyrene foamed plasticss, 0.01～0.2 part of water soluble resin, 0.05～0.2 part of polystyrene solvent, 0.3～0.8 part in water, 0.005～0.1 part of surfactivity auxiliary agent.
Polystyrene foamed plastics comprises: waste and old polystyrol foam, polystyrene finished product foam;
The polystyrene solvent comprises: vinyl acetic monomer, methylene dichloride, benzene, dimethylbenzene etc.;
Water soluble resin comprises: polyvinyl acetate emulsion, polyacrylic acid emulsion, polyvinyl alcohol, 107 glue:
The surfactivity auxiliary agent is cement hardener, opal (OP), tween type tensio-active agent.
Concrete technology is as follows:
Polystyrene foamed plastics is cleaned, is ground into particle below 3 millimeters, add cement, water soluble resin, polystyrene solvent, surfactivity auxiliary agent and water, after stirring, be injected in the building materials mould, the health slaking is 3 days under the room temperature, gets building materials prefabricated components of the present invention.
Positively effect of the present invention is: the regeneration polystyrene foamed plastics, eliminate white pollution, and reduce production costs, light weight, energy-conservation, utilization of waste material can be made into insulating brick (plate), hollow brick building prefabricated components such as (plates).λ＜the 0.1w/m.k of product of the present invention, ultimate compression strength＞1.5Mpa, unit weight＜30kg/m
