Description

Polymer cement materials
Technical field
The present invention relates to technical field of chemical paint, and in particular to a kind of Polymer cement materials.
Background technology
Mortar is mixed and stirred in proportion with inorganic coagulation material and fine aggregate and water, also referred to as mortar.For building by laying bricks or stones and smearing Grey engineering can be divided into masonry mortar and decorative mortar, the former for brick, stone, building block etc. build by laying bricks or stones and component installation;Afterwards Person is then used for the plastering on the surfaces such as metope, ground, roofing and beam column construction, to reach the requirements such as protection and decoration.Normal sands Besides adding water to be configured to paste with gypsum, lime paste or clay adding of fiber reinforcing material, referred to as in pulp material Ash, cream, mud or clay.There are commonly hemp-fibred plasteves(Mix the lime paste of hemp cut), paper strip mixed lime mortar(Mix the lime paste of paper muscle), stone Cream ash(Lime paste and paper muscle or glass fibre etc. are mixed in the plaster of paris)With mix plaster(A small amount of lime and wheat straw are mixed in clay Or straw).
According to composition material, ordinary mortar can also be divided into:1, lime mortar:It is made according to a certain ratio by lime paste, Sha Heshui At, be generally used for intensity requirement it is not high, not by moist masonry and coat of plaster.2, cement mortar:By cement, sand and water by certain Proportioning is made, and is generally used for masonry, metope or ground etc. in wet environment or water.3, mixed mortar:In cement or lime sand Appropriate admixture such as flyash, diatomite etc. is added in slurry to be made, to save cement or lime consumption, and improve mortar and it is easy Property.Common mixed mortar has cement-lime mortar, cement clay mortar and lime clay mortar etc..
New ordinary mortar of mixing should have good workability, the mortar after hardening that should then have required intensity and bonding Power.The workability of mortar is related with its mobility and water-retaining property, is generally grasped according to construction experience or is determined by testing.Mortar Compression strength indicate that common ordinary mortar label has 4,10,25,50,100 etc. with grade of mortar.It is high to intensity requirement and Important masonry just needs the mortar with No. 100 or more.The cohesive force of mortar enhances with the raising of its label, also with masonry Deng surface state, cleaning whether, moist degree and construction and maintenance condition it is related.It therefore, generally will be first by brick before laying bricks It waters, to enhance the cohesive force between brick and mortar, it is ensured that masonry quality.However conventional cement mortar is typical brittleness material Material, compression strength are high, and tensile strength, flexural strength and adhesion strength are low, poor toughness, easy to crack.Accordingly, it is difficult to meet engineering The requirement of durability and construction efficiency greatly limits its application in construction projects.By largely testing The study found that polymer is added in conventional cement mortar can greatly improve the performance of cement mortar, thus rapidly building, The fields such as traffic, water conservancy and chemical industry are used widely, especially answering in waterproof construction, the Practical Projects such as heat-insulation and heat-preservation With, and the production and application of polymer-modified cement mortar meets circular economy and the demand for development of conservation-minded society.
But the major part of conventional Polymer cement materials addition is the poor rubber powder of water resistance, is seldom utilized resistance to Soda acid, resistance to bubble, the macromolecule emulsion of excellent combination property lead to material acid and alkali-resistance, erosion-resisting poor performance, and due to matching The square inadequate science of design aspect, causes strength of coating low, can not ensure the safety constructed in next step.
