The invention relates to an intelligent segmental temperature control system of a wind power blade die, which is provided based on the technical theory that segmental temperature control is bound to be carried out based on the differences on the formed region thickness of a designed blade structure and the energy-saving purpose can be achieved by lowering the dependence on external heating in a curing manufacturing procedure by utilizing the reaction exothermic character of a matrix material. To achieve the purpose, the invention adopts the technical measures of the construction of a die segmental temperature control pipeline, which ensures that each temperature segment can be heated or cooled independently based on requirements on thermal energy in the curing manufacturing procedure; the establishment of an intelligent temperature control system, wherein temperature and hardness data of the die and a blade shell can be captured to judge whether heating setting, exothermic peak initiating temperature and the states of completion degree, gel curing degree and the like are completed or conform to design values; and antecedent technical measures, wherein energy consumption is saved by utilizing the reaction heat of materials per se to heat and reaction and temperature control are combined to match the design of a temperature curve, which are helpful for obtaining the blades with uniform curing and excellent quality and can improve the production efficiency as a characteristic.

The invention relates to inorganic paste for internal thermal insulation of buildings and a preparation method thereof. The inorganic paste is mainly prepared from the following components in parts by weight: 6-15 parts of inorganic cementing material, 3-6 parts of a polymer emulsion, 20-25 parts of a light heat-insulating material, 0.1-0.5 part of cellulose, 0.5-1 part of dispersible adhesive powder, 0.1-0.3 part of fibers, 0.0-0.1 part of an air entraining agent, 0.04-0.06 part of a film-forming agent, 0.1-0.5 part of a retarder, 0.2-0.5 part of a hydrophobic agent, 0.1-0.5 part of a water reducing agent, 0.1-0.5 part of a thickening agent and 50-70 parts of water. According to the invention, the inorganic paste overcomes the following problems: a plate joint exists after existing internal thermal insulation materials for buildings are spliced; after putty finish paint is painted on the plate joint, cracking is easy to occur, and fireproof performance is poor; and water needs to be added on site for stirring during construction, which leads to inconvenient construction, dust pollution and environmental pollution. The single-component inorganic paste material is prepared by selecting the light heat-insulating filler, the inorganic cementing material and the polymer emulsion and matching the above substances with other components in the system, can be subjected to integral batch scraping, and is free of cracking risk; and the inorganic paste is prefabricated, and construction can be carried out without adding water and stirring on site.

The invention discloses an adhesive special for sand aerated concrete boards and a preparation method of the adhesive. The adhesive comprises, by weight percentage, 25-30% of Portland cement, 50-58% of quartz sand, 15-20% of sand aerated concrete board waste, 1.5-2.0% of redispersible latex powder, 0.1-0.3% of hydroxypropyl methyl cellulose ether, 0.1-0.3% of wood fibers, 0.04-0.08% of starch ether and 0.1-0.2% of polypropylene fibers. The adhesive is good in water-retaining property and adhesive property, small in shrinkage ratio, high in crack resistance and less prone to interface crack generation, the recycled sand aerated concrete board waste is used as the raw material, and consistency with the color of a wall after filling is achieved.

The invention belongs to the technical field of building materials, and concretely discloses protective surface mortar. The protective surface mortar comprises the following components, by mass: 200-450 parts of cement, 350-750 parts of fine sand, 10-40 parts of redispersible latex powder, 10-50 parts of heavy calcium carbonate, 1-5 parts of polypropylene short fibers, 1-8 parts of hydroxypropyl methyl cellulose, 1-15 parts of a water reducer and 1-8 parts of a polymer water repellent. The protective surface mortar of the invention has good bonding strength, flexibility and water resistance, is convenient in construction, non-toxic, green and environmentally friendly, and can be applied to an external wall insulation system to effectively reduce wall cracking, water leakage, peeling, stripping, falling off and the like.
