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
The technology of the present invention relate to make of weeds agricultural crop straw and environmental protection flame retardant one pack system polyurethane foam glue be incubated, energy-conservation, earthquake proof building, house owed by a citizen brick and prefabricated components.
Background technology
Current, city and country is still built building, house owed by a citizen with common brick cement brick, and building a house with common brick cement brick one is the poor waste of the heat-insulating property fuel of warming oneself in a large number, and exterior wall adds warming plate and holds fire hazardous.The 2nd, destroy a large amount of land resource and reduce farmland area; The 3rd, bake bricks and waste national mass energy with coal; The 4th, with coal bake bricks discharge 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 human life; The 6th, the high cost that builds a house that increases of fortune brick expense.As the substitute products of common brick and cement brick; by weeds agricultural crop straw and environmental protection flame retardant one pack system polyurethane foam glue 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; save the energy; can save heating fuel 60% than brick house a winter; anti seismic efficiency is good simultaneously, can protect people's life security when earthquake.Weeds, agricultural crop straw belong to the renewable sources of energy, get do not enter to use not complete, pollution-free, the environmental protection that builds a house, is the construction material that human survival is too busy to get away.
Summary of the invention
The object of this invention is to provide and a kind of make insulation, energy-conservation, antidetonation, resistance to compression, counter-bending, environmental protection, fire-retardant, standard size building, house owed by a citizen brick and prefabricated components with weeds, agricultural crop straw and environmental protection flame retardant one pack system polyurethane foam glue, this product is suitable for city, the buildings such as earthquake-proof frame building, farm dwelling, villa, hotel, army's barracks, school, kindergarten, monastery, temple are built in rural area.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 by the following technical programs;
