Embodiment 1

[0017] In the process of thermosetting phenolic resin polymerization, 0.4% to 2.0% of molecular chain control agent is added, specifically: t-dodecyl mercaptan, 2-methylstyrene dimer, and the ratio of the two is 1:2. Effectively maintain the length of the molecular chain, reduce the conversion speed of the resin to the stage, keep the resin in the B stage for a long time, and extend the shelf life of the mesh. It can ensure that the mesh is not sticky or discolored for at least 6 months, meeting the requirements of automated production.

Embodiment 2

[0019] Take 28.00 parts of ethanol and 45.00 parts of novolac resin, stir to dissolve and mix, then add 1.00 parts of high temperature resistant coupling agent, 3.00 parts of ester plasticizer, after the above solution is fully dissolved, then add 3.00 parts of organic amine resin in turn Coupling agent and 20.00 parts of thermosetting phenolic resin, fully stir evenly, take the glass fiber mesh cloth and dip it in the evenly stirred solution, and dry it in an oven at 120℃ to measure its tensile strength. The test result is: CNP8 ×8-420 glass fiber mesh cloth after dipping treatment, the warp and weft tensile strength are both> 4000N / mm. Since 1.00 part of the molecular chain control agent is added to the organic amine-based crosslinking agent, the effect of Example 1 is also provided.

Embodiment 3

[0021] Take 27.10 parts of ethanol and 48.00 parts of novolac resin, stir to dissolve and mix, then add 0.90 parts of high temperature resistant coupling agent and 4.00 parts of ester plasticizer, after the above solution is fully dissolved, then add 2.00 parts of organic amine resin in turn Coupling agent and 18.00 parts of thermosetting phenolic resin, fully stir evenly, take the glass fiber mesh cloth and immerse it in the evenly stirred solution, and dry it in an oven at 120℃ to measure its tensile strength. The test results are: warp and weft Tensile strength in all directions> 4000N / mm. The organic amine-based crosslinking agent contains 0.80 part of the molecular chain control agent, and therefore, the effect of Example 1 is also provided.

Abstract

The invention discloses a thermoplastic and thermosetting resin reinforcement mesh that is formed by immersing mesh cloth in resin solvent. The resin solvent consists of the following components: 30.0-58.0 percent of thermoplastic phenolic resin; 15.0-25.0 percent of thermosetting phenolic resin; 0.1-2.0 percent of coupling agent; 1.0-5.0 percent of plasticizer; 0.5-8.0 percent of crosslinker; 0.4-2.0 percent of molecular chain control agent; and 25.0-28.0 percent of solvent. The product has the advantages of being excellent in weather resistance, meeting the requirements of different regional customers and especially adapting to damp and megathermal climate of oceans; overcoming the difficulty that common resin meshes are easy to become sticky and discolor during long term of marine transport; enhancing the adhesion between resin and glass fiber, promoting the tensile strength of the mesh and lowering the elongation rate; and simultaneously solving the interface adhesion technology between the mesh resin and sand, improving the adhesion strength between the mesh resin and the sand, bearing high-speed run and not dropping sand and prolonging the service life of grinding wheels.

Description

Technical field [0001] The invention relates to a thermoplastic and thermosetting resin reinforced mesh, in particular to a mesh formed by impregnating glass fiber cloth with a resin solvent. Background technique [0002] Disadvantages of similar products on the market at present: the resin is in the B stage for a short time, is easy to be sticky, inconvenient to store and use, cannot meet the needs of continuous production, and cannot withstand high temperatures. Summary of the invention [0003] The main task of the present invention is to provide a thermoplastic and thermosetting resin reinforced mesh, in particular to a thermoplastic and thermosetting resin reinforced mesh that is resistant to high temperatures, can be stably controlled in an uncrosslinked state, and is conducive to subsequent processing. . [0004] In order to solve the above technical problems, a thermoplastic and thermosetting resin reinforced mesh sheet of the present invention is formed by the mesh shee...
