Abstract
A composite phenolaldehyde plastic for moulding is proportionally prepared from phenolic resin, fully sulfurized nano-class nitrile rubber, Mg-salt crystal whisker, solidifying agent, lubricant, organic cellulose and inorganic filler through mixing and reaction at 80-120 deg.C for 3-5 min. Its advantages are high resistance to high temp and flame, and high strength.
Description
Technical field
The present invention relates to a kind of heat-resisting, toughness reinforcing, fire-retardant composite phenol formaldehyde mould plastic and preparation method thereof.
Background technology
Phenolaldehyde moulding compound is the synthetic materials that is developed and applied the earliest on the human history.
Its reaction formula is:
It has the characteristics of inexpensive, good insulating, good heat resistance, and is widely used in fields such as domestic cookers, electronic apparatus and automobile making.But its fragility is big, and the remarkable shortcoming of intensity difference has also limited its further application in national economy.
Along with the progress of science and technology, high-tech product constantly occurs, and the phenolaldehyde moulding compound of original Application Areas has been proposed higher performance requriements again.Thereby traditional phenolaldehyde moulding compound carried out modification, and overcome fragility, improve physical strength, and make the further raising on the original basis of its thermotolerance and flame retardant resistance, be the important topic that the phenolaldehyde moulding compound industry faces.
The present phenolaldehyde moulding compound industry of China, production mostly be that low gear is inferior, universal, performance is close the trade mark, it is very fierce to vie each other.And the phenolaldehyde moulding compound of high-performance, high added value must import.The restriction that this phenomenon is serious the sound development of China's phenolaldehyde moulding compound industry.
Therefore the novel phenolaldehyde moulding compound of researching and developing high-performance, high added value is an urgent demand that the current market requirement and scientific-technical progress propose material industry.
Summary of the invention
The objective of the invention is provides a kind of composite phenol formaldehyde mould plastic and preparation method thereof in order to overcome above-mentioned shortcoming.Adopt the nanometer paracril that traditional phenolaldehyde moulding compound is carried out toughening modifying, and the adding magnesium salt whisker is promoted intensity, thermotolerance and the flame retardant resistance of material comprehensively.
The invention discloses a kind of composite phenol formaldehyde mould plastic, this plastic raw materials comprises following component:

Above component all by weight.
Magnesium salt whisker adopts coupling agent to carry out conventional surface treatment, and coupling agent is one or more in silane, titanic acid ester, aluminic acid ester and the zirconate, and consumption is the 0.3-1% of magnesium salt whisker amount.
Solidifying agent is one or more in hexamethylenetetramine, Paraformaldehyde 96, the Resins, epoxy.
Lubricant is one or more in stearic acid, Zinic stearas, calcium stearate, stearic amide, stearic acid butyl ester, ethylene bis stearic acid amide, the methylene bis stearic amide.
Organic cellulose is one or more in wood powder, cotton fibre, the paper fiber.
Mineral filler is one or more in lime carbonate, talcum powder, mica powder, magnesium oxide, calcium hydroxide, hydrated aluminium silicate, the aluminium hydroxide.
The preparation method of composite phenol formaldehyde mould plastic is that the mineral filler of lubricant, 60-100 part organic cellulose and 30-60 part of solidifying agent, 1-5 part of magnesium salt whisker, 10-20 part of full sulfuration butyronitrile nano-rubber, 5-10 part of resol, 5-20 part of 100 parts mixes, reacted 3-5 minute down at 80-120 ℃, cooling promptly gets this composite phenol formaldehyde mould plastic.
Can with consumption earlier the mineral filler and full sulfuration butyronitrile nano-rubber premix of full sulfuration butyronitrile nano-rubber consumption 0.5-1%, the mineral filler of surplus is mixed together evenly with full sulfuration butyronitrile nano-rubber, resol, solidifying agent, magnesium salt whisker, lubricant, the organic cellulose sneaked out in advance, reacted 3-5 minute down at 80-120 ℃, cooling promptly gets this composite phenol formaldehyde mould plastic.
Positive progressive effect of the present invention is that this composite phenol formaldehyde mould plastic has high heat-resisting, high strength, fire-retardant character.Can satisfy the high request of new high-tech product to material, the technical progress of industries such as China's national defense, communication, electronic apparatus, automobile making is had positive pushing effect, social effect is remarkable.The present invention has simultaneously given enough attention in environmental protection and human body secure context, not only active effect is played in environment protection, has also created favourable condition for products export.
