Embodiment 1

[0048] Embodiment 1: A kind of ceramizable resin material:

[0049] This embodiment provides a ceramizable resin material, comprising: 100 parts by weight of modified epoxy resin, 30 parts by weight of glass powder, 40 parts by weight of wollastonite, 5 parts by weight of methyltetrahydrophthalic anhydride, light-burned magnesium oxide 35 parts by weight of powder, 14.7 parts by weight of modified grossular garnet powder; that is, the weight ratio of modified grossular garnet powder and lightly burned magnesia powder is 0.42:1;

[0050] The ceramizable resin material is prepared by the following method:

[0051] 1) Prepare modified epoxy resin:

[0052] Bisphenol A epoxy resin (epoxy value 0.52mol / 100g) is mixed with N-methyl-2-(2-aminoethyl)-pyrrolidine according to the molar ratio of 1:0.65, stirred evenly at room temperature, and the stirring speed is 200r / min, heat up to 95°C at a rate of 8°C / min, continue to stir for 1h, then add 4,4-diaminodiphenylmethane of 42% of the...

Embodiment 2

[0060] Example 2: Another ceramizable resin material:

[0061] This example provides another ceramizable resin material. The components and preparation method are basically the same as in Example 1, except that in this example, in the process of preparing the modified epoxy resin, the bisphenol A ring The mixing molar ratio of oxygen resin (epoxy value 0.52mol / 100g) to N-methyl-2-(2-aminoethyl)-pyrrolidine is 1:0.3.

Embodiment 3

[0062] Example 3: Another ceramizable resin material:

[0063] This embodiment provides another ceramizable resin material. The components and preparation method are basically the same as in Example 1, except that in the process of preparing modified epoxy resin in this embodiment, bisphenol A epoxy The mixing molar ratio of resin (epoxy value 0.52mol / 100g) to N-methyl-2-(2-aminoethyl)-pyrrolidine is 1:0.5.

Abstract

The invention belongs to the technical field of composite materials, and particularly relates to a ceramizable resin material as well as a preparation method and application thereof. The provided ceramizable resin material is obtained by blending modified epoxy resin serving as a base material with a curing agent, glass powder, wollastonite, nano-scale coal gangue powder and light calcined magnesia powder and then conducting curing. The components play a synergistic role. The ceramizable resin material has the advantages of excellent mechanical properties, high impact strength, high ablation performance, good flame retardant property, excellent weather resistance and humidity and heat resistance, and long service life, and can be used as a resin material for embossments.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a ceramizable resin material and a preparation method and application thereof. Background technique [0002] With the development of the economy and the progress of society, people's pursuit of life is getting higher and higher. More and more people like to hang and place various art decorations at home. Relief is a product of the combination of sculpture and painting. One of the most popular art decorations. Relief is a kind of sculpture, which uses compression to process objects, and uses perspective and other factors to express three-dimensional space. Reliefs are generally attached to another plane, so they are used more in architecture and can often be seen on utensils. Due to its compressed characteristics, it occupies less space, so it is suitable for decoration in many environments. In recent years, it has played an increasingly important role i...
