Abstract
The invention provides a wear-resistant material used for constructing basic steel plates, comprising a basic layer material and a surface layer material, wherein the basic layer material comprises the components by weight parts: 2 to 7 parts of bond, 2 to 7 parts of cement and 3 to 8 parts of sand; the surface layer material comprises the components by weight parts: 30 to 70 parts of cement, 30 to 80 parts of sand, 0.1 to 2.0 parts of water reducing agent, 0.05 to 1 part of thickening agent, 0.03 to 2.0 parts of water retention agent and 0.05 to 3.0 parts of anti-cracking agent. The wear-resistant material has the characteristic of good integrity of constructed cement-base wear-resistant material, overcomes a joint defect produced by blocky splicing of a wear-resistant plate because an integral wear-resistant layer forms organic integration, is overcome, has good anti-impact toughness; increases the softness of the material and reduces elastic modulus and the brittleness of the material by treating the basic layer material, can release the impact function of the material, and enables the wear-resistant material and the steel plates to form a whole by the bonding performance of the material and the steel plates through the basic layer material, thereby preventing the wear-resistant material from generating damage due to hollowing.
Description
Technical field
The present invention relates to a kind of special-purpose high-abrasive material, is the high-performance abrasion-proof material that a kind of structures that can be used for some industrial circle steel plate bases need wear-resistant protective layer.
Background technology
At industrial circles such as metallurgy, electric power, petrochemical industry, coal and chemical industry; Structures such as silo, hopper, ore deposit groove and slag runner, its top layer is in the wearing and tearing scouring state for a long time, and structures receive serious destruction; Must wear-resistant protective layer be set on the top layer, play the effect of protection basic unit.In the middle of these structures, quite a few is arranged is the steel plate basis, and this requirement to high-abrasive material is just harsh more.The high-abrasive material of conventional use mainly contains wearable plate, Portland cement base high-abrasive material etc., and there is certain defective in these materials aspects such as globality, every square meter cost, the feature of environmental protection after cohesiveness, shock resistance, construction, show:
(1) globality is poor.Traditional wearable plate mainly is to be connected with structures through clay or bolt, and the polylith tiling forms whole then.Its globality is relatively poor, and it is the destructive weak link that the two boards material connects seam crossing, under the ballistic effect of material, is easy to breakage occur, abrasion-proof backing block is come off, and then cause big area to come off, and loses the effect of protection basic unit.
(2) shock resistance is poor.Himself fragility of the maximum glass cermaic plate and calendering crystallite plate of consumption at present, and common cement-base wear-resistant material is bigger, and Young's modulus is high, especially under the condition on steel plate basis, receives the intensive shock action, is easy to destroy.
(3) bad adhesion.High-abrasive material and steel plate base bond are bad, and when receiving intense impact, sheet material separates generation and comes off with steel plate, and Portland cement base high-abrasive material and steel plate form hollowing, reduce the shock resistance of material, and then increase the breakage of material.
Summary of the invention
The objective of the invention is to above-mentioned defective, for the industry storage structures on steel plate basis provide a kind of wear resisting property excellence, good integrity, shock resistance is high, adhesive property is good environmental protection and the wear-resistant material of moderate cost.
The present invention is a kind of wear-resistant material that can be used for the steel plate foundation construction, is made up of base material and two kinds of materials of surface material, gets final product through mixing according to proportioning respectively.Its components in mass portion number calculates as follows:
Base material:
2～7 parts in tackiness agent
2～7 parts of cement
3～8 parts in sand;
Described tackiness agent is epoxy resin, emulsion or urethane; Cement is ordinary Portland cement, silicate cement or quick hardening sulphoaluminate cement, and its strength mark is not less than 42.5; Sand is natural sand or artificial sand, and its particle diameter is no more than 3mm.
Surface material:
30～70 parts of cement
30～80 parts in sand
0.1～2.0 part of water reducer
0.05～1 part of tackifier
0.03～2.0 part of water-holding agent
0.05～3.0 part of anti-fissuring agent.
Described cement is ordinary Portland cement, silicate cement or quick hardening sulphoaluminate cement, and its strength mark is not less than 42.5; Sand is artificial silica sand or natural sand, and Mohs' hardness is greater than 7; Water reducer is poly carboxylic acid or naphthalene series high-efficiency water-reducing agent; Tackifier are Vilaterm or PS; Water-holding agent is an ether of cellulose, and molecular weight is 50000～150000; Anti-fissuring agent is organic fibre or steel fiber.
The mechanism of action of the present invention is: inorganic cement and sand are combined as basic unit as tackiness agent with organic epoxy resin, emulsion or urethane; Guarantee the bonds well on material and steel plate basis; Reduce elasticity modulus of materials in addition; Improve shock resistance, have certain shock-absorbing effect.Surface material is a jointing compound with the ordinary Portland cement or the quick hardening sulphoaluminate cement of high grade, and the aggregate gluing that wear resisting property is good forms wearing layer together jointly; Anti-fissuring agent and tackifier synergy can prevent phenomenons such as crackle and hollowing peel off; Water-holding agent then plays remarkable improve workability, application property, close-burning effect.
During construction, stir after base material of the present invention mixed three kinds of components according to proportioning, brush the steel plate basis with round brush or hairbrush; Surface material adds the water of 13%～16% (weight percent), adopts forced mixer to mix and stir or wet mortar is mixed and stirred in manual work, and the mode of taking routine to plaster is smeared above the base material and got final product.When closing on initial set, optical processing is received on the surface, the external coating interface treating agent can obtain better effect.
The invention has the beneficial effects as follows: (1) has the characteristics of good integrity after the construction of cement-base wear-resistant material, and whole wearing layer forms an organic whole, overcomes the fault in seam that the block splicing of wearable plate produces; (2) toughness is good, handles through base material, increases the flexibility of material, reduces Young's modulus, has reduced the fragility of material; Can slow down the shock action of material; (3) increased the bonding of material and steel plate through base material, made wear-resistant material and steel plate form an integral body, prevented that wear-resistant material from producing destruction because of hollowing.
