Abstract
The invention discloses a method for preparing concrete kerbstones and paving bricks from nonmetal powder of waste circuit boards. Recycled nonmetal powder of the waste circuit boards is mixed and stirred with cement, water, sand and stone in a certain proportion, and compression moulding is carried out, thus the concrete kerbstones and paving bricks are prepared. The method for preparing the concrete kerbstones and paving bricks from the nonmetal powder of the waste circuit boards has the advantages that nonmetal powder taken as fine aggregate and stones taken as coarse aggregate are added into the cement, properties of the concrete kerbstones and paving bricks which are obtained through compression moulding are ideal, The concrete kerbstones and paving bricks obtained by the method meet China building material industry standard of concrete kerbstone JC899-2002 and China standard of concrete paving brick GB28635-2012, the concrete kerbstone and paving brick can serve as kerbstone and paving brick, the waste circuit boards are recycled, waste of secondary resources and land resources is avoided, and the environment is protected.
Description
Technical field
The invention belongs to material of construction and junk and recycle field, be specifically related to a kind of method of utilizing waste and old circuit board non-metal powder to prepare kerbstone and pavior brick.
Background technology
The quickening of the day by day universal and update speed of rapid development of economy, electronic product, makes people day by day improve the demand of various electric equipment productss.A large amount of productions of electronic product have formed increasing electronic waste.Waste and old circuit board is the chief component of electronic waste, China is burn and bury to the main processing mode of waste and old circuit board, these modes are contaminate environment both, has caused again the waste of secondary resource and land resources, and recovery and reuse waste and old circuit board becomes urgent problem.
Summary of the invention
The object of the invention is to: a kind of method of utilizing waste and old circuit board non-metal powder to prepare kerbstone and pavior brick is provided, non-metal powder in waste and old circuit board is combined with traditional material of construction, make the desirable kerbstone of performance and pavior brick.
Technical solution of the present invention is: by a certain amount of cement, water, sand, stone and waste and old circuit board non-metal powder mix and blend, compression moulding, makes Kerb of concrete and pavior brick; Kerbstone testing standard is with reference to the building material industry standard < < of JC 899-2002 People's Republic of China (PRC) Kerb of concrete > >, and pavior brick testing standard is with reference to GB 28635-2012 State Standard of the People's Republic of China < < concrete road pavement brick > >; The mass ratio of cement, water, sand, stone, waste and old circuit board non-metal powder is 1:(0.3 ~ 0.5): (1.0 ~ 1.5): (2.0 ~ 6): (0.3 ~ 4).
Wherein, described cement is any in silicate cement, ordinary Portland cement or other kind cement that meets concrete performance requirement.
Wherein, described sand is any in quartz sand, river sand or other kind sand that meet performance requriements.
Wherein, described stone is cobble or rubble, and its nominal maximum aggregate size is 10mm or 20mm.
Wherein, described waste and old circuit board non-metal powder particle diameter is 0.4 ~ 2 mm.
The present invention is using sand and waste and old circuit board non-metal powder as fine aggregate, stone adds in cement as coarse aggregate, the Kerb of concrete of compression moulding and pavior brick performance are desirable, meet the < < of country of the building material industry < < of JC 899-2002 People's Republic of China (PRC) Kerb of concrete > > standard HeGB 28635-2012 People's Republic of China (PRC) concrete road pavement brick > > standard, can be used as kerbstone and pavior brick uses, recovery and reuse waste and old circuit board, avoid the waste of secondary resource and land resources, protection of the environment.
