Abstract
The invention relates to a method for producing bricks and prefabricated parts used for a building and a civilian building by utilizing weeds, crop straw and a polyurethane foam adhesive. The method comprises the following steps of: processing raw materials: cutting the weeds and straw into segments with the length of 20-40cm by utilizing a straw cutter, disorganizing the weed and crop straw segments by adopting a waste wheel machine to eliminate stress, and drying by adopting a drying machine; mixing grass rubber: mixing in a glue mixer, then carrying out compression moulding, injecting rubber into a grass base by adopting a high-pressure pump so as to be subjected to extrusion moulding, eliminating stress of the weeds and the crop straw and spraying the polyurethane foam adhesive into the waste wheel machine so as to be subjected to impact moulding; performing mould pressing, extruding and stamping, wherein hot pressing is adopted; and postprocessing: naturally cooling, placing embedded parts in a rotating aperture manner or directly placing the embedded parts during mould pressing. The products have the advantages of good heat preservation, energy conservation and earthquake-proof effects, strong antiflaming and insect prevention effects and high compression resistance, bending resistance and impact resistance. When the products are used for building a wall, cement is used for smearing a wall surface to prevent grass bricks and prefabricated parts from being damaged, thus the aim of fire protection is achieved.
Description
Technical field
Technology of the present invention relates to weeds agricultural crop straw and environmental protection flame retardant one pack system polyamine fat vacuole foam adhesive makes insulation, energy-conservation, earthquake proof building, house owed by a citizen brick and prefabricated components.
Technical background
Current, building, house owed by a citizen are still built with the common brick cement brick in city and rural area, and building a house with the common brick cement brick one is a large amount of heating of heat-insulating property difference waste fuel, and exterior wall adds warming plate and causes fire easily.The 2nd, destroy a large amount of land resources and reduce farmland area; The 3rd, bake bricks and waste national mass energy with coal; The 4th, with coal bake bricks the discharging great amount of carbon dioxide work the mischief to human survival; The 5th, poor seismic behavior, it is brick house that earthquake causes maximum injury to the human life; The 6th, the high cost that builds a house that increases of fortune brick expense.Substitute products as common brick and cement brick; With weeds agricultural crop straw and environmental protection flame retardant one pack system polyamine fat vacuole foam adhesive mixing manufacture brick and prefabricated components product specification, standard, to build building, the house owed by a citizen cost that comprehensively builds a house low; High insulating effect is saved the energy, and can save heating fuel 60% than brick house a winter; Anti seismic efficiency is good simultaneously, can protect people's life security during earthquake.Weeds, agricultural crop straw belong to the renewable sources of energy, get do not advance to use intact, pollution-free, the environmental protection that builds a house is the construction material that human survival be unable to do without.
Summary of the invention
The purpose of this invention is to provide and a kind ofly make insulation, energy-conservation, antidetonation, resistance to compression, counter-bending, environmental protection, fire-retardant, standard size building, house owed by a citizen with brick and prefabricated components with weeds, agricultural crop straw and environmental protection flame retardant one pack system polyamine fat vacuole foam adhesive, this product is suitable for the city, buildings such as earthquake-proof frame building, farm dwelling, villa, hotel, army's barracks, school, kindergarten, monastery, temple are built in the rural area.The production cost is low, economic and practical, insulation, anti seismic efficiency are good, is to replace the appropriate products of common brick cement brick.The above-mentioned technical purpose of the present invention is to be achieved through following technical scheme;
