specific Embodiment approach 1

[0014] Embodiment 1: In this embodiment, the fiber-reinforced zinc-aluminum phosphate-based composite material is mainly made of fiber-reinforced materials and zinc-aluminum phosphate cementitious materials through compression molding; wherein the fiber-reinforced materials are heat-treated.

[0015] The fiber-reinforced zinc-aluminum phosphate-based composite material of the present invention has a compact structure, excellent performance, and good heat resistance stability. The bending strength of the composite material at room temperature can reach 60MPa-140MPa, and the application range is wide.

[0016] In this embodiment, the fiber-reinforced material accounts for 30-75% of the weight of the fiber-reinforced zinc-aluminum phosphate-based composite material.

specific Embodiment approach 2

[0017] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a protective coating is added on the surface of the fiber reinforced material. The protective coating is a silane coupling agent coating, an inorganic nanoparticle sol coating or a silicone resin coating. layer; the silane coupling agent is one of silane coupling agent KH-550, silane coupling agent KH-560, and silane coupling agent A-151; the inorganic nanoparticle sol is SiO 2 Sol, Al 2 o 3 Sol, TiO 2 One of the sols; the silicone resin is one of the methyl silicone resin and the phenyl silicone resin; the inorganic nanoparticle sol is prepared by a sol-gel method.

[0018] In this embodiment, the protective coating accounts for 0.05-2% of the weight of the fiber reinforced material. Described silane coupling agent is all commercially available products.

specific Embodiment approach 3

[0019] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the fiber-reinforced material accounts for 40-60% of the weight of the fiber-reinforced zinc-aluminum phosphate-based composite material. Others are the same as in the first or second embodiment.

Abstract

The invention relates to fiber-reinforced zinc and aluminum phosphate matrix composite and a preparation method thereof, which relate to fiber-reinforced composite and the preparation method thereof. The invention solves the problems of high curing temperature of the prior aluminum phosphate material or the carcinogenicity of chrome in a chrome and aluminum phosphate material. The fiber-reinforced zinc and aluminum phosphate matrix composite of the invention is prepared from the fiber-reinforced material and gelation material of zinc and aluminum phosphate; the preparation method comprises the following processes: under condition of 200 to 600 DEG C, heat treatment is carried out for the fiber-reinforced material for 10 minutes to 1 hour; then the fiber-reinforced zinc and aluminum phosphate matrix composite is prepared according to a compression molding technology; the process parameters are as follows: the molding temperature is 85 to 300 DEG C, the molding pressure is 2 to 15MPa, and the molding time is 6 to 35 hours. The product of the invention has high temperature resistance and good mechanical properties, without toxic substance; the product of the invention can be cured under 170 DEG C, with the bending strength under the room temperature up to 70 to 140MPa; the thermal weight loss is less than 8 percent when the composite is heated to 600 DEG C. The method of the invention is simple in technology, easy in material obtaining, low in cost, easy in popularization and utilization, and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a fiber reinforced composite material and a preparation method thereof. Background technique [0002] With the advancement of science and technology, the working efficiency of the engine has been continuously improved, so the requirements for the thermal properties of the materials have been continuously increased, and the research work on high temperature resistant structural materials has been paid more and more attention. Phosphate materials are an important high-temperature resistant material developed on the basis of cement, refractory materials and ceramics. It combines the main advantages of the three, with high temperature resistance, high strength, excellent dielectric properties, oxidation resistance and good The structural designability and small thermal expansion coefficient have attracted extensive attention at home and abroad in recent years. At present, there are two main types of phosphate materials widely stud...
