Description
Technical field
The present invention relates to a kind of binder material, specifically the biological environmental production type binding agent take the fluffy seedcake dregs of rice of alkali as main raw material.
Background technology
Binding agent is widely used in every field, such as briquette binder, pellet binder, glued board bonding agent and sand-fixing binder etc.Use at present maximum binding agents and make " synthetic adhesive " by polymer chemistry and petroleum chemistry.
Binding agent mainly is to be used in desert and the serious area of soil drifting in the field of fixing the sand, and is used for the bonding of the grains of sand, and purpose is to form bonding course, prevents that dust storm from playing dirt.Traditional sand-fixing binder can be divided into: grout class, water glass class, petroleum products class and high molecular polymer super absorbent resin lipid.These sand-fixing binders can make the earth's surface sandy soil be fixed, and have certain stability and water-retentivity, thus the purpose that reaches tackling quicksand and administer Desertification Soil.But some material costs are high, and some materials can not be created good water and soil environment for plant-growth, some materials even can be to environment.Such as, petroleum products class material is used rear hard degradation, and prolonged stay causes secondary environmental pollution in the sandy soil of top layer.Novel sand-fixing binder comprises: workers and peasants' forestry byproducts is carried out the synthetic several classes such as composite sand consolidation material of the ecotope sand fixation material of modification, the microorganism sand fixation material that utilizes microbial technique and organic and inorganic.They have that use properties is good, natural resources and energy resources consumption less, with the plurality of advantages such as the ecotope consistency is good.
What binding agent adopted usually in the glued board field is urea-formaldehyde resin, is heated easily to produce free formaldehyde, causes secondary pollution, and this also is the major cause that indoor formaldehyde exceeds standard.So it is the research direction of current main-stream that the development low levels does not even contain the binding agent of free formaldehyde.
Binding agent is that the accumulation of salt in the surface soil, moisture absorption phenomenon appear in water glass in actual use usually adopting sodium silicate binder, water glass aspect the carton bonding, and adhesive is come off, and effect is bad.So adopt as an alternative product of environment-friendly type binding agent, wide prospect arranged.
In a word, " synthetic adhesive " that polymer chemistry and petroleum chemistry are made, some material costs are high, some performances are not good, have in addition environment caused secondary pollution, be detrimental to health.Therefore, study not only environmental protection but also cheap binding agent important realistic meaning is arranged.
