Abstract
The invention provides a cement-based abrasive material used for the lining of industrial storing structure. The material is prepared by compounding and evenly mixing the following components with parts by weight: 35-75 parts of cement, 40-90 parts of sand, 0.1-2.0 parts of a water reducing agent, 0.15-1.5 parts of a flexibilizer, 0.3-3.0 parts of a water retaining agent and 0.5-3.0 parts of microcapsule quicklime. The beneficial effects of the material are that (1) after construction, the integrity is good, a whole abrasive layer forms an organic integer, which overcomes joint defect caused by splicing the conventional abrasive material with block shape; (2) the toughness is good, compared with a cast stone plates and a rolling crystallite plate, the material properly reduces the modulus of elasticity and the brittleness; (3) the material can be applied to a higher temperature environment; (4) the construction can be carried out under the condition of negative temperature; (5) no poisonous gas and waste are produced in the construction process, which is helpful to protect the environment.
Description
Technical field
The present invention relates to a kind of special-purpose high-abrasive material, specifically a kind of high-performance cement base wear-resistant material that can be used for the structures wear-resistant protective layers such as silo, hopper, ore deposit groove and slag runner of industrial circles such as metallurgy, electric power, petrochemical industry, coal and chemical industry.
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 are used for storage material more and handle pulp water; its top layer is in the wearing and tearing scouring state for a long time; make structures be subjected to serious destruction; must wear-resistant protective layer be set on the top layer, play the effect of protecting group layer concrete or steel plate.The material that tradition is used for wear-resistant protective layer comprises glass cermaic plate, calendering crystallite plate, wear-resisting steel plate, nylon liner plate etc., and there is such or such defective in these materials at aspects such as shock resistance, construction back globality, every square meter cost, the feature of environmental protection, show:
(1) globality is poor.Mostly traditional high-abrasive material is abrasion-proof backing block is connected with structures by clay or bolt, and connecting seam is exactly that pears are cut the destructive weak link, under the effect of shearing force; be easy to occur damaged; and then the generation chain reaction, cause abrasion-proof backing block to come off, lose the effect of protection basic unit.
(2) shock resistance is poor.The for example at present glass cermaic plate of consumption maximum and calendering crystallite plate, material self fragility is bigger, and the Young's modulus height under the shock action of coal cinder ore etc., is easy to destroy, especially unconfined position, liner edge.
(3) weathering resistance is poor.Some organic polymer abrasion-proof backing blocks such as nylon liner plate, urethane liner plate, polyethylene liner plate and polystyrene liner plate etc. should not be used for hot environment (greater than 200 ℃), and every square meter involves great expense.The glass cermaic plate that is used to bond solidifies slowly at low temperatures with the furan mastic that rolls the crystallite plate, and (above 200 ℃) are softening under the comparatively high temps, and application property is poor, and ageing resistance is poor after solidifying.
(4) not environmental protection.Organic solvent in some binding agents (as furan mastic) has big volatility, under the environment of ventilation condition differences such as silo, to workmen's health formation harm greatly.
(5) binding agent application property under subzero temperature such as organic clay is poor, even can not construct, and brings very big inconvenience to engineering.
Summary of the invention
The objective of the invention is at above-mentioned defective, for industry such as metallurgy, electric power, petrochemical industry, coal and chemical industry storage structures provide a kind of wear resisting property excellence, good integrity, shock resistance height, environmental protection and moderate cement-base wear-resistant material.
A kind of cement-base wear-resistant material that can be used for industry storage structures liner of the present invention is composite by components such as cement, sand, water reducer, toughner, water-holding agent, microcapsule unslaked limes, gets final product through mixing.Its component is measured as follows by weight:
35～75 parts of cement
40～90 parts in sand
0.1～2.0 part of water reducer
0.15～1.5 part of toughner
0.3～3.0 part of water-holding agent
0.5～3.0 part of microcapsule unslaked lime.
Described cement is ordinary Portland cement or quick hardening sulphoaluminate cement, and its strength mark is not less than 42.5; Sand is artificial quartz 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; Toughner is polyethylene or polystyrene; Water-holding agent is an ether of cellulose, and molecular weight is 10000～150000; Microcapsule unslaked lime be with 20 parts of (weight ratio) unslaked limes and 1 part of (weight ratio) saturated fatty acid in proportion the blend grinding form to fineness＜0.63mm.
The mechanism of action of the present invention is: ordinary Portland cement or quick hardening sulphoaluminate cement with high grade are jointing compound, and the aggregate gluing that wear resisting property is good forms wearing layer together jointly; Microcapsule unslaked lime and toughner synergy play chemical shrinkage and dry shrinkage in the compensation water cement-based material solidification process, prevent phenomenons such as crackle and hollowing peel off; Water-holding agent then plays remarkable improve workability, application property, close-burning effect.
During construction, with the water of cement-base wear-resistant material adding of the present invention 13%～15% (weight percent), adopt forced mixer to mix and stir into wet mortar, the mode of taking routine to plaster is smeared treated structures surface and is 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) cement-base wear-resistant material construction back good integrity, whole wearing layer forms an organic whole, overcomes the fault in seam that the block splicing of conventional high-abrasive material produces; (2) toughness is good, compares with glass cermaic plate, calendering crystallite plate etc., has suitably reduced Young's modulus, has reduced the fragility of material; (3) this wear-resistant material can be applicable to comparatively high temps environment (below 500 ℃); (4) this wear-resistant material can carry out constructing under the subzero temperature condition; (5) do not produce any toxic gas and waste in the construction process, help environmental protection.
