Abstract

The invention discloses glass fibre reinforced plastic septic-tank glue. The glass fibre reinforced plastic septic-tank glue is prepared from the following raw materials in parts by weight: 20-40 parts of unsaturated polyester resin, 10-20 parts of epoxy modified phenolic resin, 8-15 parts of glass fibres, 5-15 parts of a flame retardant, 6-18 parts of silicon carbide micro powder, 4-10 parts of quartz powder, 1-5 parts of calcium stearate, 3-10 parts of a titanate coupling agent, 0.1-0.5 part of an anti-oxidant, and 0.1-0.3 part of a lubricant; and the unsaturated polyester resin is preparedby the following process comprising the following steps: mixing maleic anhydride, tetrahydrophthalic anhydride, adipic acid, propylene glycol and diethylene glycol, heating up and performing stirringreaction, adding N-(polydimethylsiloxane) maleimide and dibenzoyl peroxide to heat and perform stirring reaction; and adding hydroquinone and styrene to uniformly mix to obtain high-temperature-resistant unsaturated polyester resin. The glass fibre reinforced plastic septic-tank glue has good high temperature resistance and good mechanical property, is good in processability, is low in toxicity and is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a rubber material for glass fiber reinforced plastic septic tanks and a preparation method thereof. Background technique [0002] Septic tank is an indispensable drainage treatment equipment in the construction field. It is used to discharge domestic wastewater into municipal pipelines after primary treatment or into lower-level sewage treatment facilities for advanced treatment. Most of them are buried. In the early days, septic tanks were usually made of bricks, reinforced concrete or steel plates, but they all had obvious defects. In recent years, glass fiber reinforced plastic septic tanks have gradually been selected by most construction units. The scientific name of FRP is glass fiber reinforced plastic, and the septic tank storage tank made of FRP has the characteristics of strong corrosion resistance, no leakage, easy construction, and slow aging s...
