Abstract

A kind of preparation method of stalk-polystyrene composite thermal-insulated plate, is related to a kind of preparation method of energy-saving building materialses, and this method is：First maize straw natural drying is done, and additional electrical heating, drying, make the moisture content in stalk below 5%；Dried corn stalk powder is broken to 5~10 millimeters of length；The ratio of the maize straw after crushing and polystyrene raw material particle in mass ratio 15~30: 1 is mixed again, compound is added in board mould；In a mold by 100 DEG C of vapor, make foamed polystyrene, by stalk, granules of polystyrene is inter-adhesive obtains light-weight building energy-conserving thermal insulation board together.The present invention is applied to building trade, alternative traditional clay brick and building block, and its manufacture craft is simple, and raw material is easy to get, and cost is low；Its product quality is light, high insulating effect.

Description

A kind of preparation method of stalk-polystyrene composite thermal-insulated plate
Technical field
The present invention relates to a kind of preparation method of energy-saving building materialses, more particularly to a kind of preparation method of stalk-polystyrene composite thermal-insulated plate.
Background technology
With the increasingly exacerbation of the global energy and crisis of resource, people also increasingly pay attention to building energy conservation.Traditional clay brick, due to not only largely wasting the energy, and serious damage arable land in sintering procedure, wastes land resource, the pernicious gas and dust of discharge are also polluted the environment, and very big harm is brought to people's health with building block.Also, its energy-saving effect is also poor, therefore traditional clay brick is prevented or restricted from using with building block by most of areas, saves the energy, green insulating board for building will be applied more and more.
The content of the invention
It is an object of the invention to provide a kind of preparation method for the building energy-saving heat-insulating board that cost is relatively low, deadweight is small, thermal conductivity factor is low, caking property is good.This method is using stalk and polystyrene as primary raw material, make foamed polystyrene by vapor high temperature, stalk, granules of polystyrene is inter-adhesive together, and substantial amounts of blind hole is formed in polystyrene, the pore closure between stalk interplantation fibres is got up again, makes substantial amounts of blind hole be present among whole sheet material so as to reach the effect of insulation.
The purpose of the present invention is achieved through the following technical solutions：
A kind of preparation method of stalk-polystyrene composite thermal-insulated plate, its preparation method are：First maize straw natural drying is done, and additional electrical heating, drying, make the moisture content in stalk below 5%；Then dried corn stalk powder is broken to 5~10 millimeters of length again；The ratio of the maize straw after crushing and polystyrene raw material particle in mass ratio 15~30: 1 is mixed again, compound is added in board mould；In a mold by 100 DEG C of vapor, make foamed polystyrene, by stalk, granules of polystyrene is inter-adhesive obtains light-weight building energy-conserving thermal insulation board together.
Advantages of the present invention is with effect：
1. the present invention is using stalk and polystyrene as raw material, its raw material is readily available, and manufacture craft is simple, lower cost.
2. the present invention effectively make use of stalk resource, the product quality of production is light, high insulating effect.
