Problems solved by technology

In addition, many of the completed insulated walls suffered from insulation peeling problems
[0004] As we all know, traditional thermal insulation boards are basically divided into two types: the first type is organic material thermal insulation boards, such as polystyrene boards, extruded plastic boards, polyurethane boards, etc. Its advantages are good thermal insulation performance and low cost, and its disadvantages are: 1. The fire resistance of organic materials is poor, which is Class B fire performance; 2. The thermal expansion and contraction coefficients of organic materials and inorganic cement mortar have a large gap, and the bonding ability is insufficient, and the problem of falling off will occur after 3-5 years of use
The second is the inorganic material plain silk rock wool insulation board, which has the advantages of good fire resistance and moderate heat preservation performance. The disadvantages are: 1. Rock wool is made of pressed, loose structure and poor tensile performance; 2. Loose structure water absorption High, easy to cause loss of heat preservation effect due to water absorption; 3. Insufficient ash sticking ability, easy to weather and short service life, easy to fall off
The inorganic composite polystyrene grade A insulation board modifier produced by this method has no quality at all, specifically: 1. There is no internal support aggregate, resulting in poor compressive strength; 2. The amount of rubber powder added Instability will cause the thermal insulation board to be unstable; 3. The lack of internal high-end thermal conductivity materials will cause the thermal conductivity of the thermal insulation board products to exceed the standard; 4. The lack of internal strengthening and health-preserving agents will cause the cement-based thermal insulation board to be cured and unable to solidify; 5. The absence of internal waterproofing agents will cause The waterproof performance of insulation board products is very poor; 6. Without a skeleton proppant, the insulation board products do not have rigidity; 7. Without slurry suspension, it is difficult to complete the production of insulation boards
The insulation board products produced with this modifier cannot meet the standard at all
