Description
Technical field
The present invention relates to technical field of chemical paint, be specifically related to a kind of Polymer cement materials.
Background technology
Mortar mixes and stirs in proportion with inorganic coagulation material and fine aggregate and water to form, and also claims mortar.For building by laying bricks or stones and plastering engineering, can be divided into masonry mortar and plastering mortar, the former builds by laying bricks or stones and Components installation for brick, stone, building block etc.; Latter is used for plastering of the surfaces such as metope, ground, roofing and post and beam construction, to reach the requirements such as protection and decoration.Also having plenty of in ordinary mortar material adds water with gypsum, lime putty or clay adding of fiber strongthener is mixed with paste, is called ash, cream, mud or clay.Conventional have hemp-fibred plaster (mixing the lime putty of hemp cut), paper strip mixed lime mortar (mixing the lime putty of paper muscle), gypsum ash (mixing lime putty and paper muscle or glass fibre etc. in the plaster of Paris) and mix plaster (mixing a small amount of lime and wheat straw or straw in clay).
According to composition material, ordinary mortar also can be divided into: 1, lime mortar: be made up according to a certain ratio of lime putty, Sha Heshui, is generally used for requirement of strength is not high, be not subject to humidity masonry and coat of plaster.2, sand-cement slurry: be made up according to a certain ratio of cement, Sha Heshui, is generally used for the masonry in wet environment or water, metope or ground etc.3, mixed mortar: the suitable adulterant of admixture such as flyash, diatomite etc. is made in cement or lime mortar, to save cement or lime consumption, and improves the workability of mortar.Conventional mixed mortar has cement lime mortar, cement clay mortar and lime clay mortar etc.
Newly mix ordinary mortar and should have good workability, the mortar after sclerosis then should have required intensity and cohesive force.The workability of mortar is relevant with water-retentivity with its mobility, generally grasps according to construction experience or is determined by test.The ultimate compression strength of mortar represents with mortar mark, and conventional ordinary mortar label has 4,10,25,50,100 etc.The masonry high and important to requirement of strength, just needs the mortar with more than No. 100.The cohesive force of mortar strengthens with the raising of its label, also with the condition of surface of masonry etc., whether clean, moist degree and construction and maintenance condition relevant.Therefore, generally first brick to be watered before laying bricks, to strengthen the cohesive force between brick and mortar, guarantee masonry quality.But conventional cement mortar is typical hard brittle material, its ultimate compression strength is high, and tensile strength, folding strength and cohesive strength are low, poor toughness, easy to crack.Therefore, be difficult to the requirement meeting project durability and operating efficiency, greatly limit its application in construction work.Find through a large amount of experimental studies, the performance that polymkeric substance can improve sand-cement slurry is greatly added in conventional cement mortar, so be used widely in fields such as building, traffic, water conservancy and chemical industry rapidly, particularly at waterproof construction, application in the Practical Projects such as heat-insulation and heat-preservation, and the production and application of polymer-modified cement mortar meets the demand for development of recycling economy and conservation-minded society.
But the major part that the Polymer cement materials of routine adds is the poor rubber powder of water tolerance, seldom utilize acid and alkali-resistance, resistance to bubble, the macromolecule emulsion of excellent combination property, cause material acid and alkali-resistance, erosion-resisting poor performance, and due to the inadequate science in formulating of recipe aspect, cause strength of coating low, next step safety of constructing cannot be ensured.
