preparation example Construction

[0062] The preparation method of each embodiment phosphate glass fiber:

[0063] (1) Batch preparation

[0064] Mix the raw materials containing the above components according to the formula. In the formula, MgO, Na 2 O, K 2 O, Fe 2 o 3 , CaO and other phosphates with corresponding substances are introduced, B 2 o 3 by H 3 BO 3 introduced, and the rest of P by P 2 o 5 introduce.

[0065] (2) batch material processing

[0066] due to P 2 o 5 Absorb moisture and release a lot of heat at the same time. After the batch is weighed, wait for the moisture absorption reaction of the batch to complete in the fume hood. Before the reaction starts, spray 3% of the total amount of the batch with secondary water.

[0067] (3) Glass melting

[0068] The phosphate glass batch is continuously fed into the glass melting furnace 2 by an automatic feeder. It is used as a radiation heating device 3 to initially melt the batch material, and then use the glass itself as a resistance ...

Abstract

The invention discloses biocompatible phosphate based continuous glass fiber and a fabric prepared from the same. The biocompatible phosphate based continuous glass fiber comprises, by mole, 35-55 parts of P2O5, 10-40 parts of CaO, 10-30 parts of MgO, 2-20 parts of B2O3, 0-24 parts of Na2O, 0-5 parts of K2O, 1-10 parts of Fe2O3 and 0-15 parts of MxOy, wherein MxOy is Ag2O or CuO2 or Ga2O3. The biocompatible phosphate based continuous glass fiber has good fiber forming processing property, good fiber forming property, strong spinnability, good chemical stability, and controllable degradation speed and biological activity, and the mechanical property is matched with that of bone tissue; the mechanical performance of a material obtained by compounding a textile product processed from the fiber with PLA and other degradable high-molecular polymers reaches the level of human bones.

Description

technical field [0001] The application relates to a biocompatible phosphate-based continuous glass fiber and a fabric prepared therefrom, belonging to the field of biomedical materials. Background technique [0002] Bioactive glass (bioactive glass) is a kind of material that can repair, replace and regenerate body tissues, and can form a bond between tissues and materials. It is used for bone tissue engineering in bone repair or bone replacement. 40 years ago, American scientist LHench discovered that 45S5 bioactive glass has the characteristics of being able to combine with human bone tissue. The weight percentages of each oxide in the glass component are: SiO 2 : 45.0%; CaO: 24.5%; Na 2 O: 24.5%; P 2 o 5 : 6.0%. A series of improvements were subsequently made to this type of glass formulation for clinical applications such as artificial dentistry and orthopedic treatment. However, silicate bioactive glass takes a long time to degrade, which takes 1 to 2 years. SiO 2...
