preparation example Construction

[0026] The preparation method of described FRP is:

[0027] (1) Stir the bisphenol epoxy vinyl resin, phenolic resin, calcium carbonate, and aluminum hydroxide with a high-speed mixer for 0.5-1.5 hours, mix thoroughly and evenly, and the temperature during stirring is 50-80°C.

[0028] (2) Then add ultraviolet absorber, curing agent and release agent, keep the temperature at 50-80°C, stir for 0.5h-1.5h to obtain a mixture.

[0029] (3) The mixture is placed in a fiberglass pultrusion machine for pultrusion to obtain the required fiberglass. The temperature of the pultrusion is 200-220°C, the ambient temperature needs to be kept at 10-30°C, the pultrusion speed=25+(20-environment temperature)×0.85, unit: cm / min.

Embodiment

[0032] 1. Prepare 16 groups of FRP according to the above method, and carry out extrusion molding under the condition of pultrusion molding temperature of 210°C. The actual preparation parameters of each group of FRP are shown in Table 1, and the values ​​of each component in the table refer to parts by mass. Both the curing agent 1 and the curing agent 2 are purchased from Changzhou Changsheng FRP Material Co., Ltd., the curing agent 1 is an unsaturated resin curing agent, and the curing agent 2 is an epoxy resin curing agent.

Abstract

The invention belongs to the field of special equipment for airports, and in particular relates to a novel glass fiber reinforced plastic and a preparation process. The specific technical solution is: a glass fiber reinforced plastic, the formula of which includes: in parts by mass, 30 to 40 parts of bisphenol epoxy vinyl resin, 25 to 30 parts of phenolic resin, 10 to 15 parts of calcium carbonate, and 15 to 20 parts of aluminum hydroxide. 30-40 parts of glass fiber. The FRP provided by the present invention has a bending strength of up to 462MPa and a shear strength of only 11MPa; products made of the FRP are less likely to break when subjected to strong winds, and are very easy to break and break when impacted, and are very suitable for use in On the relevant facilities of the airport flight area.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a novel glass fiber reinforced plastic and a preparation process. Background technique [0002] All kinds of equipment used at the airport should have a certain degree of fragility. According to the introduction of fragility in Part 6 of the "Airport Design Manual", all kinds of facilities in the flight area, such as meteorological equipment, radio navigation equipment, etc., may pose a safety hazard to the flight, so these equipment are required to Fragmentation must occur immediately upon impact, ie it should be friable. However, due to various subjective and objective reasons, many equipment in the flight area still use the steel frame structure as support, which cannot meet the fragility. If it is possible to provide a material that can be applied to the flight area, has good fragility, and will not break under ordinary environmental conditions, it will greatl...
