Description
Technical field
The present invention relates to cast the comprehensive utilization of solid waste, especially relate to composition and method that the dust that utilizes the resin sand casting engineering to produce prepares cast paint.
Background technology
The existing ripe casting old-sand regeneration process for producing line of foundry resin sand regeneration power.Resin-bonded sand cast form after the cast, through knockout, fragmentation, sieve, magnetic separation, cooling, regeneration, mulling, moulding operations such as (coremaking) constantly recycle.Handle each operation in resin sand regeneration the dust removal by ventilation point all is set, collect dust, the dust of capture is stored in the deduster, reaches to concentrate after certain quantity to abandon, and pollutes environment.These dust granules are very thin, and generally greater than 140 orders, major part is a silica.Resin sand casting dust in producing at present abandons substantially, the also packing materials that are used for construction material of the research of its comprehensive utilization more, and as casting dust/cement based light composite material, incorporation can be near 50%.So far also do not find to utilize foundry resin sand regeneration power dust to prepare the open report and the public use of cast paint.
Foundry resin sand regeneration power dust is that resin sand regeneration back produces, mainly from the coating dust, and silica dust and resin dust.The foundry resin sand regeneration power dust of collecting from typical Foundry Works carries out analysis of components, finds that foundry resin sand regeneration power dust contains the silica about 60～80%, 20～40% alundum (Als, low amounts of resin.Casting bauxite paints aggregate composition generally contains the silica about 40～60%, 40～60% alundum (Als.Resin is the bonding agent of coating.Therefore the casting of its basic composition thing and resin sand is suitable with bauxite paints.Can reach the bauxite composition as long as add 20～40% schmigels (alundum (Al) among the aggregate.The dust granularity also can be accomplished identical with bauxite through screening with grinding.
Summary of the invention
The purpose of this invention is to provide a kind of prescription and method of utilizing foundry resin sand regeneration power dust to prepare the cast paint aggregate; with foundry resin sand regeneration power dust is that main aggregate prepares cast paint; not only Zhi Bei coating property satisfies the casting requirement; production cost is low; reduce dust emission; be beneficial to environmental protection, when producing ironcasting or small casting steel, also might realize casting the partly or entirely recycling of dust.

Contain the silica about 50～80% in the described foundry resin sand regeneration power dust, 20～50% alundum (Als, low amounts of resin.
The method for preparing cast paint by foundry resin sand regeneration power dust: it is characterized in that its concrete steps are:
1) with the foundry resin sand regeneration power dust screening, grinds to form 260～400 order granularities;
2) be 40～90% by the foundry resin sand regeneration power dust percentage by weight, granularity is 140～400 orders, the schmigel percentage by weight is 10～60%, granularity is 280～320 orders, be prepared into the aggregate or the foundry resin sand regeneration power dust percentage by weight 10～40% of coating, bauxite (280～320 order) percentage by weight 60～90%, granularity is 280～320 orders, be prepared into the aggregate or the foundry resin sand regeneration power grain weight amount percentage 100% of coating, granularity is the preparations of 140～400 orders, fully mix, be prepared into the aggregate of coating;
5) well an amount of suspending agent, binding agent, dispersant and the additive of weighing;
6) add aggregate and stir into required coating, or carry out ball milling or colloid mill is prepared into coating.The granularity of foundry resin sand regeneration power dust is 300～350 orders.
Can be used for preparing casting resin sand, clay-bonded sand, water-glass sand, disappearance by the cast paint of foundry resin sand regeneration power dust preparation and touch cast paints such as casting.
Foundry resin sand regeneration power dust of the present invention prepares the cast paint aggregate element: foundry resin sand regeneration power dust (140～400 order) 40～90%, schmigel (280～320 order) 10～60%, perhaps foundry resin sand regeneration power dust 10～40%, bauxite (280～320 order) 60～90%, perhaps foundry resin sand regeneration power powder (140～400 order) 100%.Can be used for preparing casting resin sand, clay-bonded sand, water-glass sand disappears and touches the aggregate of cast paints such as casting.
The concrete steps that foundry resin sand regeneration power dust of the present invention prepares the cast paint method are:
1) with the foundry resin sand regeneration power dust screening, grinds to form 260～400 order granularities;
2) be 40～90% by the foundry resin sand regeneration power dust percentage by weight, granularity is 140～400 orders, the schmigel percentage by weight is 10～60%, granularity is 280～320 orders, be prepared into the aggregate or the foundry resin sand regeneration power dust percentage by weight 10～40% of coating, bauxite (280～320 order) percentage by weight 60～90%, granularity is 280～320 orders, be prepared into the aggregate or the foundry resin sand regeneration power grain weight amount percentage 100% of coating, granularity is the preparations of 140～400 orders, fully mix, be prepared into the aggregate of coating.
3) well an amount of suspending agent, binding agent, dispersant and the additive of weighing;
4) add aggregate and stir into required coating, or carry out ball milling or colloid mill is prepared into coating.
Perhaps by above-mentioned prescription, add directly that weighing well an amount of suspending agent, binding agent, dispersant and additive carry out ball milling or colloid mill is prepared into coating.
