Resin rubber powder is high-pressure, spray dried and has enhanced activity with a variety of * * * Micropowder Homopolymer, which can significantly improve the bonding ability of bonding mortar with extruded board (bonding with micro permeability) and its own tensile strength, have good construction performance of falling resistance, water retention and thickening, outstanding water resistance, freeze-thaw resistance, heat aging resistance, simple ingredients, easy use, and low cost compared with the same period. Physical and chemical performance index test item index Appearance powdery solid content 99% Bulk density g/L950-1000 Ash% ＜ 1 PH value 6-8 Film forming temperature ℃ 0 Product description YYD-01 (resin type) special glue powder for extruded board system is a special product for cement-based series building materials. This product has excellent solubility with cement and can be completely dissolved in cement-based dry mixed mortar paste, After curing, the strength of the cement will not be reduced, which not only maintains the bonding effect, film-forming property and flexibility, but also has good weather resistance and stability. The obvious advantage of this product is its super bonding property and crack resistance. After drying, it can effectively prevent acid air from affecting wall It is resistant to pulverization and deliquescence after being wet. It is widely used in bonding mortar and crack resistant mortar wall materials, and can greatly reduce production costs. Application example 1. Reference formula for production of bonding mortar (XPS board insulation system) ① PO42.5 ordinary silicon cement 400KG/T ② quartz sand 600KG/T ③ (resin type) special glue powder 10KG/T ④ HPMC2KG/T directly add water and mix evenly, The water cement ratio is 20~22%. It can be used after being placed for 5~10 minutes. It is forbidden to construct at a temperature below 5 ℃. It is better to use up within 30 minutes at a time. The bonding thickness is 3-5 mm. After 28 days, 80% of the bonding effect can be achieved. The dosage is about 5 KG/㎡. Quality parameter item inspection item Quality index Tensile bond strength of thermal insulation bonding mortar and cement mortar at normal temperature ≥ 0.60 Water resistance ≥ 0.50 Freeze thaw resistance ≥ 0.50 and extruded board at normal temperature ≥ 0.1 or extruded board damaged Water resistance ≥ 0.1 or extruded board damaged Freeze thaw resistance ≥ 0.1 or extruded board damaged Operational time, H 1.5-4 Construction method reference: JGJ/144-2004 Technical Specification for External Wall Thermal Insulation Engineering Product quality reference: JG149-2003 Expansion Extruded Board Thin Plastering External Wall Thermal Insulation System 2. Plastering mortar (XPS board thermal insulation system) Production reference formula ① PO42.5 ordinary silica cement 400KG/T ② quartz sand 600KG/T ③ (resin type) Special glue powder for extruded board system 10KG/T ④ HPMC2KG/T ⑤ polypropylene fiber 1KG/T ⑥ grey wood fiber 3KG/T directly add water and mix evenly, with water cement ratio of 20~22%, and it can be used after being placed for 5~10 minutes. Construction standard requirements: the thickness of mortar for the overlay of the extruded board bottom layer is 2~3mm. After the grid cloth is pasted and compacted, 1~2mm thick mortar is applied. The reinforced part is 5~7mm thick. After 28 days, 80% of the solidification and bonding effect can be achieved. The dosage is about 5KG/㎡. Quality parameter item inspection item Quality index Tensile bond strength of thermal insulation plastering mortar and extrusion board resistance to freezing and thawing ≥ 0.50 Normal temperature ≥ 0.1 or extrusion board damage Water resistance ≥ 0.1 or extrusion board damage Freeze thawing resistance ≥ 0.1 or extrusion board damage Operational time, h 1.5-4 flexibility (28d compression ratio) ≤ 3 24 Water absorption, G/㎡≤ 1000 Crack resistance: no cracks below 5 mm Water permeability (24h), ml ≤ 3 Wet flow density of water vapor, g/㎡. h ≥ 1.00 Construction method reference: JGJ/144-2004 Technical Specification for External Thermal Insulation Engineering of External Walls Product quality reference: JG149-2003 Expansion Extrusion Board Thin Plastering External Wall External Temperature Protection System Precautions: 1. Feeding should not be input at one time; 2. When polypropylene fiber needs to be added, it should be put into the cement to disperse, because the fine particles of cement can eliminate the static electricity of the fiber, so that the polypropylene fiber can be dispersed; 3. The mixing shall be even, but the mixing time shall not be too long, 15 minutes is better, and the sand and cement mixed for a long time are easy to precipitate and delaminate; 4. It is necessary to adjust the dosage of additives and add appropriate amount of HPMC according to seasonal changes; 5. Avoid additives or cement caking due to moisture; 6. It is strictly prohibited to stack and use together with acid substances; It is prohibited to use below 7.5 ℃ in construction. Low temperature construction will cause major engineering quality problems, resulting in non adhesion between plastering mortar and insulation board, which is a engineering quality problem for which there is no remedial plan later. Packing and storage: 1.25 KG, chemical compound paper plastic packaging bag, lined with PVC film; 2. The warranty period is 2 years, which must be waterproof and moisture-proof. After opening the package, it must be tied and sealed, with smell.
