preparation example Construction

[0024] The preparation method of the glass fiber reinforced polyester mineral composite material includes the following steps (such as figure 2 ):

[0025] a) Sieving granite particles or sand particles into 6 levels according to the particle size range: 0.1mm~0.6mm, 0.6mm~2mm, 2mm~3.5mm, 3.5mm~5mm, 5mm~7mm, 7mm~10mm , Clean and dry the granular aggregates of different particle size grades, and then weigh them according to a certain mass ratio according to the different particle size grades and mix them evenly; b) Weigh the glass fibers and use the silane coupling agent soaking method to surface treat the glass fibers; c) Weigh the liquid synthetic resin, diluent, toughening agent and curing agent and mix them into a uniform resin system, add the surface-treated glass fiber to the uniformly mixed resin system, and stir to make it evenly distributed; d) mix The uniform solid particle aggregate is added to the homogeneous mixture of the resin system and glass fiber, and continues to...

Abstract

The invention discloses a glass fiber reinforced polyester mineral composite material and a preparation method thereof, which belong to the technical filed of composite materials. The glass fiber reinforced polyester mineral composite material comprises an adhesive substrate, an aggregate and a glass fiber, and is prepared by the steps of evenly mixing the adhesive substrate, the aggregate and the glass fiber, casting and curing the mixture, and the like, wherein the mass fraction of the adhesive substrate is 9 to 20 percent; the mass fraction of the aggregate is 79 to 90 percent; and the mass fraction of the glass fiber is 0.1 to 1 percent. The composite material has excellent damping property and physical and mechanical properties, improves the compressive strength by 15 to 25 percent compared with a polyester mineral material without reinforced fiber, improves the damping ratio by 9.5 to 23 percent, and can be used as an excellent mechanical basic element material.

Description

Technical field: [0001] The invention relates to a composite material and a preparation method thereof, in particular to a glass fiber reinforced polyester mineral composite material and a preparation method thereof, and belongs to the technical field of composite materials. Background technique: [0002] The development of modern science and technology has increasingly higher requirements for machining efficiency, precision and quality. High speed and high precision have become the two major development trends of modern machining technology. It is required to shorten the processing time and auxiliary time, and increase the metal removal rate and cutting amount. . The increase of cutting amount is easy to cause vibration during processing, so the machine tool system is required to have better dynamic and static performance, thermal stability, high damping and other performance. The main way to solve the vibration problem is to optimize the structure of the machine tool and use ne...
