Description
Technical Field
The invention relates to the field of building external wall insulation boards, in particular to a fireproof flame-retardant high-molecular light building external wall insulation composite board and a preparation process thereof.
Background
At present, the building stock of China is 500-600 hundred million square meters, a part of the building stock is high-energy-consumption buildings, 20 hundred million square meters of the new buildings are built every year, and the proportion of the building energy consumption to the total energy consumption is more than 30%. The heat loss of the building mainly comprises an outer wall, a window, ventilation, a roof, the ground, a staircase and the like, wherein the heat loss of the outer wall accounts for the maximum and reaches 26 percent, so that the heat loss of the outer wall is effectively reduced, and the heat loss of the outer wall is important for realizing energy conservation and consumption reduction of a house.
The building external wall heat insulation refers to that various materials and technologies are utilized to process the building external wall, and the heat insulation performance of the external wall is strengthened, so that the building heat insulation capacity is enhanced. The external wall heat preservation can reduce the heat transfer inside and outside the building, is favorable for maintaining the internal temperature of the building, reduces the dependence of the building on heat supply, and is a more environment-friendly building heat preservation technology. The external wall heat insulation mainly comprises three forms of external wall heat insulation, internal wall heat insulation and sandwich heat insulation, wherein the external wall heat insulation has extremely wide application range, is beneficial to protecting the main structure of a building, improving the moisture condition of a wall body, promoting the stability of room temperature, improving the waterproofness and the air tightness of the building and the like.
The building external wall heat insulation system is mostly realized based on heat insulation materials, so that the reasonable selection of the heat insulation materials is of great importance to the efficiency and the safety of the external wall heat insulation system. In recent years, under the drive of a series of beneficial factors such as national policy promotion, technical progress and the like, the real estate industry in China is steadily developed, and the heat insulation and preservation material industry in China is driven to continuously present a good development situation. The market scale of the external wall thermal insulation material in China is increased from 250.7 hundred million yuan in 2010 to 804.6 hundred million yuan in 2016, and the composite growth rate is 21.45%; in 2020, the yield of the external wall insulation material in China is 955.3 ten thousand tons, the expected yield value in 2022 is more than 2000 million yuan, the annual composite growth rate reaches 12%, and the development prospect is good.
The development of the external wall heat-insulating material in China generally goes through the following three stages: (1) the starting stage mainly comprises organic plates. At the end of the last century, buildings in northern areas of China begin to adopt external wall insulation to meet the energy-saving requirement, and the mainstream product is a foamed polystyrene board which is characterized by low cost, poor mechanical property and no fire prevention basically; in the first 10 years of this century, with the explosive growth of the building industry in China, the types of heat insulating materials including extruded polystyrene boards, polyurethane foam boards, phenolic foam boards, expanded polystyrene foam boards, perlite and the like have been increasing. At this time, the organic insulation board still occupies nearly 90% of the market share. (2) The thermal insulation material category is in a well-spraying growth stage. In the years 2010 to 2014, the areas needing to be subjected to external wall heat insulation of buildings are gradually expanded to the national range, so that the building energy-saving heat insulation industry in China shows a blowout type growth situation. (3) And (4) a class A fireproof stage. After 2014, along with the continuous increase of building fires and the obvious combustion-supporting effect of organic heat-insulating materials in the fires, GB50016 'building design fire protection standard' is urgently developed in China, the application range of the organic heat-insulating materials is limited, and meanwhile, the fact that non-combustible A-grade heat-insulating materials are required to be used by high-rise residences and public buildings is definitely pointed out, so that the A-grade heat-insulating materials are rapidly spread on the market and become mainstream products in the energy-saving and heat-insulating market of the buildings in China.
Current situation of a-level fireproof insulation board: (1) the rock wool board is an inorganic fiber board which is made of basalt serving as a main raw material through high-temperature melting processing, is a fire-proof grade A, is a mainstream grade A non-combustible insulation board in the current market, and accounts for more than 60% of the market share. The defects of the rock wool board are intensively shown in that the tensile strength of the actual board perpendicular to the board surface is low, the rock wool fiber has certain acidity, and the acid-base reaction is easy to occur with cement, and the problems of hollowing, falling and the like of the board are easy to occur. Meanwhile, rock wool fibers are carcinogenic and harm body health. (2) A-grade fireproof heat-insulating materials such as a foamed cement board, a foamed ceramic, a foamed glass, a vacuum heat-insulating board and the like have the defects of incompatibility of heat-insulating and fireproof performances, high processing cost, strict requirements on construction conditions, unstable use performance and the like. (3) An organic/inorganic composite board represented by a permeate board and a homogeneous board. The penetration plate is prepared by taking a foamed polystyrene insulation board as a base material and penetrating a certain amount of inorganic cementing material into gaps of the foamed polystyrene insulation board through a vacuum negative pressure means, so that the defects of low tensile strength and acidity of a rock wool board are overcome, the consideration of flame retardance, heat preservation and mechanical properties to a certain extent is realized, and the defects of poor plate uniformity, non-uniform properties, poor weather resistance, long curing time and the like also exist. The homogeneous board is formed by pressing and curing after inorganic materials are uniformly mixed with expanded polystyrene particles, the advantages of the penetration board are inherited, the defects of flame retardance, heat preservation and mechanical property anisotropy of the penetration board are overcome, and meanwhile, the defect of poor weather resistance is overcome by adopting ordinary silica cement or other silicate cement as a main inorganic cementing material.
The existing domestic external wall insulation board has good insulation performance of an organic board, but is easy to burn and poor in fireproof grade; the inorganic board has good fireproof performance, but low strength, easy hollowing and dropping and poor safety; the composite modified board has the heat preservation and fire resistance performances, but has the problems of low production efficiency, large cutting dust, serious pollution and the like, thereby causing a plurality of defects in the production and actual use processes:
firstly, the method comprises the following steps: easy combustion, fast flame propagation and great harm: because the board contains a large amount of organic materials, such as polyurethane foam, polystyrene foam and the like, the organic materials belong to inflammable materials, are easy to ignite, have high combustion speed, large heat release amount and rapid spread, are easy to form communication inside and outside buildings in short time, have large area of three-dimensional fire, have high fire fighting difficulty, have high toxicity of combustion products and have great harm to the personal safety.
II, secondly: high water absorption, low tensile strength and easy cracking and falling: inorganic heat-insulating boards such as rock wool and the like have poor weather resistance, are easy to absorb water, have low tensile strength and are easy to crack, fall off and the like; meanwhile, the heat conductivity coefficient is large, the heat insulation performance is poor, and the service life is short.
Thirdly, the method comprises the following steps: the energy consumption is large, the pollution is heavy, and the use is limited: the rock wool is formed by basalt high-temperature melt wire drawing and adhesive bonding, the production energy consumption is large, and rock wool fibers can stimulate the skin in the construction process and seriously cause respiratory system diseases; the rock wool has high water absorption rate and low tensile strength, and is easy to fall off to cause a smashing accident; the inorganic/organic composite board can also achieve A-level fire prevention, but the intermittent production process is adopted, so that the floor area is large, the number of cutting surfaces is large, the loss and dust are large, and the requirements of the building industry are difficult to meet.
Therefore, the invention provides a fireproof flame-retardant polymer light building outer wall heat-insulation composite board and a preparation process thereof, which can ensure the prevention of fire while heat insulation, reduce energy consumption and simultaneously realize building safety guarantee and energy conservation.
