Description
Technical field
The present invention relates to a kind of glass-fiber reinforced plastic grille low-toxicity compound type resin.
Background technology
Glass-fiber reinforced plastic grille is by glassmat skeleton, and the cold coating be wrapped in outside skeleton is formed.Because glass-fiber reinforced plastic grille is corrosion-resistant, compressive resistance is strong, and glass reinforced plastic application development speed quickly in recent years.But in practical application, according to different occasion, will also slightly distinguish glass-fiber reinforced plastic grille.In places such as waterworkss, require glass-fiber reinforced plastic grille not only corrosion-resistant anti-compression, also need the toxic ingredient reducing glass-fiber reinforced plastic grille simultaneously.Therefore, the outer field resin of glass-fiber reinforced plastic grille is particularly important.
Summary of the invention
The present invention seeks to for prior art not enough, provide a kind of transparency high, bubble-free, and there is thermotolerance and weathering resistance, resistance to compression, shock resistance, a kind of glass-fiber reinforced plastic grille low-toxicity compound type resin of reliability.
For achieving the above object, the technical solution used in the present invention is: described a kind of glass-fiber reinforced plastic grille low-toxicity compound type resin is grouped into by following raw material:
Tackiness agent metaphenylene food level resin 40-60 part;
Fire-retardant filler magnesium hydroxide 5-10 part;
Solidifying agent 65N kymene 0-40 part;
DMP305-10 part;
Thinner phenylcarbinol 1-5 part;
Silane coupling agent 1-5 part;
Filler 5-10 part;
UV light absorber 1-2 part;
Releasing agent dimethyl silicone oil 2-4 part.
Described UV light absorber is formed with hindered amine is composite by salicylate class E, benzophenone, benzotriazole, triazine-5.
Described filler is the mixture of asbestos powder, Graphite Powder 99, talcum powder, silica powder, ceramics powder.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1, metaphenylene food level resin equally has excellent corrosion resistance nature with metaphenylene resin, use temperature 50-90 DEG C, and maximum operation (service) temperature can reach 105 DEG C.Because it is nontoxic, can be used for waterworks, meat product source mill and food processing plant.
2, fire-retardant filler magnesium hydroxide currently generally acknowledged has filling, fire-retardant, the chemical agent that presses down cigarette triple functions, has nontoxic, corrosion-free and cheap advantage.When macromolecular material burns, the Absorbable rod major part combustion heat, release water vapour, slows down combustionvelocity.
3,650N polymeric amide cohesive strength is high, water-fast, wear-resisting, corrosion-resistant, and snappiness is good, and insulation, non-volatile, toxicity is little.
4, DMP30 and 650N polymeric amide uses together, can promote solidification and reaction effect.
5, phenylcarbinol is as thinner, and effect is fine, and reactive thinner can be avoided to there is the shortcomings such as price is high, volatility is large, toxicity is large.Phenylcarbinol can be well compatible with epoxy resin simultaneously, there will not be the phenomenon of migration, can promote the reaction of epoxy resin and amine, fast reaction speed; Phenylcarbinol has good hydrophobic performance, can significantly improve the gloss of coating, reduces the appearance of white birch phenomenon; Phenylcarbinol can improve the toughness of cured article.
6, silane coupling agent can reinforcing glass steel grating intensity, electrically, the performance such as water resistant, anti-weather, even if when hygrometric state, it is to the raising of matrix material machinery performance, and effect is also very remarkable.
7, filler mainly occupies volume by it and plays a role, and due to the existence of filler, the molecular chain of body material just can not occupy original whole spaces again, the segment be connected is immobilized to a certain extent, and may causes the orientation of matrix polymer.Due to the dimensional stability of filler, in the polymkeric substance of filling, the molecular chain movement in polymer interface region is restricted, and shrinking percentage reduces, and Young's modulus, hardness, rigidity, shock strength improve.
8, UV light absorber is composite with hindered amine by salicylate class E, benzophenone, benzotriazole, triazine-5, can obtain the effect than any independent UV light absorber more rationality.
9, dimethyl silicone oil is tasteless nontoxic, has physiological inertia, good chemical stability, electrical insulating property and weathering resistance, and range of viscosities is wide, and zero pour is low, and flash-point is high, and hydrophobic performance is good, and has very high resistance to shear, can help the demoulding.
10, tackiness agent metaphenylene food level resin and solidifying agent 65N polyamide-compatible are very well, and reaction can complete for two hours under normal circumstances, after adding DMP30, can play the effect accelerating solidification, within 1 hour, can complete solidification.
11, after tackiness agent metaphenylene food level resin and solidifying agent 65N polymeric amide mix, constitute the most basic skeleton, solidification is facilitated by adding DMP30, but because solidification is accelerated, the volatilization of gas, easy bubbling, by adding dimethyl-silicon oil release agent, not only conveniently stripped, the production of bubble can also be avoided.
12, under normal circumstances, filler is general only can add one or both, selects now asbestos powder, Graphite Powder 99, talcum powder, silica powder, ceramics powder four kinds of powder as mixture, improves overall over-all properties.But because filler increases more, the consistency of mineral filler and resin is poor, the silane coupling agent added in formula, makes the dispersiveness of filler and bounding force greatly improve, improves the consistency between mineral filler and resin.
13, in formula except the UV-absorber mixture low toxicity of small component, all the other formulas itself are nontoxic, and composition after hybrid reaction is also nontoxic.By the interpolation of fire-retardant filler magnesium hydroxide, even if there is special status, the major part that combustion parts produces is all water vapour.
