Problems solved by technology

However, one disadvantage of glass antibacterial agents is that they are prone to discoloration when mixed with resins; in addition, there are two major problems in the preparation of glass carrying antibacterial metal ions: one is that the glass components are different from traditional glass and contain high sodium , boron, phosphorus, etc., so the glass has a great corrosion effect on the crucible during melting. Studies have shown that 95 corundum, pure corundum, titanium carbide, etc. are difficult to adapt to, and only expensive platinum crucibles are used; the second is when melting this type of glass. , it is easy to have metal silver beads or colloidal silver deposition, so as to affect the antibacterial effect of antibacterial agents and cause waste of raw materials

[0021] 1.1 Preparation of hydroxyapatite antibacterial agent

[0022] In the present invention using Ca(OH) 2 and H 3 PO 4 As raw material, hydroxyapatite was synthesized by chemical co-precipitation, 0.5g of hydroxyapatite prepared by the above method was dissolved in 5ml of 0.1M silver nitrate solution, and then the hydroxyapatite with adsorbed silver ions was heated at 1150°C Calcined at lower temperature for 1 hour to obtain the silver-containing hydroxyapatite antibacterial agent.

[0023] 1.2 Preparation of antibacterial unsaturated polyester resin

[0024] Fully mix 100 parts of unsaturated polyester resin with 0.1 part of hydroxyapatite antibacterial agent to obtain antibacterial unsaturated polyester resin.

[0025] 1.3 Preparation of antibacterial FRP profiles

[0026] The antibacterial resin, glass fiber products and auxiliary materials are subjected to a pultrusion process to prepare antibacterial glass fiber reinforced plastic door and window profiles.

Abstract

The invention relates the antibiotic glass reinforced plastic door and window section bar and its processing method. The section bar comprises the basis materials which is unsaturated polyester resin and inorganic antibacterial agent which is hydroxyapatite antibacterial agent. The method comprises the following steps: 1 preparing the hydroxyapatite antibacterial agent; 2 homogeneous dispersing the hydroxyapatite antibacterial agent into unsaturated polyester resin; 3 drawing the said unsaturated polyester resin, fiber glass and accessory material to shape and getting the antibiotic glass reinforced plastic door and window section bar. The said antibiotic glass reinforced plastic door and window possesses the advantages of good weatherability, strong antibiosis, long antibiosis life, and simple production.

Description

technical field [0001] The invention relates to a preparation method of a building material with antibacterial properties, in particular to an antibacterial glass fiber reinforced plastic door and window profile and a preparation method. Background technique [0002] With the continuous improvement of people's living standards, people are creating a comfortable living environment for themselves that is warm in winter and cool in summer, and at the same time creates favorable conditions for the reproduction and growth of microorganisms and bacteria. Discomfort is not uncommon. On the surface of building doors and windows, due to insufficient daily disinfection and cleaning, it often becomes the most favorable place for bacteria and microorganisms to multiply, and such products directly affect people's living environment. In addition, in hospitals, pharmaceutical workshops, food preparation workshops and other places, there are special requirements for antibacterial and milde...
