Problems solved by technology

At present, the sound insulation and heat insulation mats in air conditioners, home textiles and automobile products all require their flame retardant performance to meet international or national standards, and the formula of the flame retardant felt used in large quantities is composed of ordinary fibers, flame retardants and phenolic resins. It has a certain flame retardant effect, but its obvious defects are: 1. The material of the felt is only flame retardant itself, and the burning speed is slow. If it encounters an open flame or a large fire, it will shrink or melt and burn through. , and once the fire source penetrates, it will cause damage or burning of the internal components of the product; therefore, the flame retardant effect of the interlayer cannot really be achieved
2. The composition of the flame retardant is ammonium polyphosphate, which contains ammonium, bromine and other substances, which do not meet environmental protection requirements, and will corrode metal materials such as copper pipes and iron, and pollute the environment. At the same time, phenolic resin also contains A large amount of phenol and formaldehyde harmful to human body

Embodiment 1

[0025] Example 1: By weight, 32% of high temperature resistant fiber, 40% of flame-retardant and shrink-proof polyester fiber, 25% of flame-retardant treated cellulose fiber and 3% of flame retardant are blended to form a carbonized reticular flame-retardant felt. Among them, the high temperature resistance of the high temperature resistant fiber should reach above 265°C, and the flame retardant treated cellulose fiber acts as a carbonized network after burning. The composition ratio of the flame retardant per unit weight is: microencapsulated red phosphorus P with red phosphorus content ≥ 83%: 12.7%, antimony trioxide Sb 2 o 3 : 7%; zinc borate ZnBO 3 : 71.5%; Magnesium Oxide MgO: 5%; Aluminum Hydroxide AL(OH) 3 : 4.5%; the rest is an appropriate amount of water.

Embodiment 3

[0026] Example 3: By weight, 36% of high temperature resistant fiber, 30% of flame-retardant and shrink-proof polyester fiber, 30% of flame-retardant treated cellulose fiber and 4% of flame retardant are used to blend to form a carbonized reticular flame-retardant felt. Among them, the high temperature resistance of the high temperature resistant fiber should reach above 265°C, and the flame retardant treated cellulose fiber acts as a carbonized network after burning. The composition ratio of the flame retardant per unit weight is: microencapsulated red phosphorus P with red phosphorus content ≥ 83%: 12.9%, antimony trioxide Sb 2 o 3 : 7.2%; zinc borate ZnBO 3 : 71.9%; Magnesium Oxide MgO: 5.2%; Aluminum Hydroxide AL(OH) 3 : 4.6%. The rest is an appropriate amount of water.

[0027] Embodiment 3: By weight, 37% of high temperature resistant fiber, 25% of flame-retardant and shrink-resistant polyester fiber, 33% of flame-retardant treated cellulose fiber and 5% of flame ret...

Abstract

The invention discloses a carbonized netty flame retardant felt and a method for making the same. The carbonized netty flame retardant felt consists of the following compositions by weight percentage: 32 to 41 percent of high-temperature resistant fiber, 25 to 42 percent of flame retardant and shrinkproof polyester, 25 to 38 percent flame retardant treated cellulose base fibre and 3 to 5 percent of flame retardant; microencapsulation red phosphorus P, diantimony trioxide Sb2O3, zinc borate ZnBO3, magnesia MgO and aluminium hydroxide AL(OH)3 are weighed according to a proportion and added with water in a proper amount to prepare an evenly-mixed flame retardant solvent; various fibers are respectively treated by adopting spraying, solvent removing and drying and processed to the flame retardant felt with a crossed netty structure. The carbonized netty flame retardant felt uses the self-prepared red phosphorus ammonia-free flame retardant which has high and strong flame retardance as well as shrinkage resistance and drop melting resistance, has high tensile strength and no odour and is beneficial to human health.

Description

technical field [0001] The invention relates to a flame-retardant felt in the field of fiber polymer materials and a preparation method thereof, which is used for sound-insulation and heat-insulation pads in products such as air conditioners, home textiles, and automobiles that require high flame retardancy. Background technique [0002] With the continuous expansion of the industrial use of the fiber industry, various high-performance and special fibers have emerged. High-performance fibers are a type of special fibers developed in the field of fiber polymer materials in recent years. At present, the sound insulation and heat insulation mats in air conditioners, home textiles and automobile products all require their flame retardant performance to meet international or national standards, and the formula of the flame retardant felt used in large quantities is composed of ordinary fibers, flame retardants and phenolic resins. It has a certain flame retardant effect, but its...
