Embodiment Construction

[0029] The specific implementation manner of the present invention will be described below in conjunction with an embodiment.

[0030] According to one embodiment of the glass fiber reinforced magnesia solar cooker shell composite material of the present invention, the main materials are 60-70% magnesium oxide, 30-40% magnesium chloride, and the following components by weight percentage are added:

[0031] Alkali-resistant glass fiber: 4 to 8%,

[0032] Sodium fluorosilicate: 1-2%,

[0033] Trisodium phosphate: 1.5~2.5%,

[0034] Oxalic acid: 0.5~2%,

[0035] Ferric oxide: 0.2~2%,

[0036] Talc powder: 1~3%,

[0037] 191 resin: 1.5~2.5%,

[0038] Under the condition of very low temperature, add 2-4% magnesium sulfate to the above slurry.

[0039] Its preparation process consists of the following steps:

[0040] a) Preparation of slurry:

[0041] 1) prepare magnesium chloride aqueous solution: weigh out the magnesium chloride of 30~40% by weight, be prepared into magnes...

Abstract

The invention provides a kind of glass fiber reinforced magnesia solar range shell compound material and the manufacturing method. It uses magnesia oxide and magnesium chloride as main materials. Adds in the glass fiber as reinforcing material, sodium fluosilicate which can make the material porcelain, enhancer tertiary sodium phosphate, pH conditioning agent ethane diacid, toner, plasticizing agent, talcum and magnesium sulfate. They are stired into pulp and the pulp and the glass fiber are pasted onto the solar energy stove mould alternately. It demoulds them after 24 hours. The product has a good performance.

Description

technical field [0001] The invention belongs to the technical field of new materials, in particular to a glass fiber reinforced magnesium oxide solar cooker shell composite material, which is mainly used for making solar cooker shell materials and its preparation process. Background technique [0002] The aqueous solution of magnesium oxide and magnesium chloride can form a solid material with extremely high hardness, which is called magnesia cement and is often used in building materials. This kind of magnesia cement material has the phenomenon of "returning halogen" under high temperature and humidity conditions, that is, magnesium chloride that has not yet participated in the compounding is precipitated on the surface of the material and absorbs moisture in the air to make the surface of the object moist and even produce water. beads, so it is difficult to be accepted by people. However, if it can be re-formulated, the process improved, and the phenomenon of "returning h...
