Description
Technical field
The present invention relates to a kind of fiberglass radome and preparation method thereof, more specifically to a kind of fiberglass radome and preparation method with the modification of peroxidating isobutyl methyl ketone initator.
Background technology
Fiberglass radome is owing to having good weatherability, and insulation, lightweight, intensity is high, dimensionally stable and production efficiency advantages of higher, has been widely used in wireless and a plurality of fields such as protecting sheathing antenna of mobile communication base station at present.Fiberglass radome generally all be take unsaturated polyester (UP) and is added filler and relevant auxiliary agent extrusion molding as primary raw material again, unsaturated polyester (UP) (english abbreviation UP) mainly refers to the resin by dihydroxylic alcohols and all or part of unsaturated dibasic acid condensation polymerization gained, conventionally there is better thermal endurance, insulating properties, water-fast and chemically-resistant, ageing-resistant, resin after enhancing has very high engineering properties, but in resin, conventionally add this class material of styrene as thinner by the reduced viscosity of resin to can the range of work, again because it is more volatile, comparatively widely used methyl ethyl ketone peroxide cannot react with it thoroughly, cause the styrene residual quantity in goods higher, harmful to human and environment.Therefore need to carry out modification to reduce the styrene residual quantity in goods to product.
Peroxidating isobutyl methyl ketone is formulated by desensitizer, peroxidating ketone and relevant auxiliary agent, belongs to organic peroxide, and micro-yellow transparency liquid is the new material of a kind of of many uses, the excellent performance that gets up of development in recent years, applies more extensive.Be generally to make for material modified as unsaturated polyester resin solidifying agent and other promoter associating, but be also out of use in the middle of the preparation of fiberglass radome.
Summary of the invention
The object of the invention is to solve and in above-mentioned present technology, have the higher problem of fiberglass radome products benzene ethene residual quantity, a kind of fiberglass radome with the modification of peroxidating isobutyl methyl ketone is provided, improved the wave penetrate capability of product, reduced its DK value, styrene residual quantity significantly reduces.
The present invention simultaneously also provides its preparation method, and process is simple, and finished product rate is high, and production cost is lower.
Technical scheme of the present invention is as follows:
Fiberglass radome with the modification of peroxidating isobutyl methyl ketone of the present invention, it is to be made by the raw material of following weight proportion: glass fibre 50%-70% and resin formula material 30%-50%, wherein resin formula material is made by the raw material of following parts by weight: 100 parts of unsaturated polyester (UP)s, 0.8～1.5 part of release agent, 0.5～1 part of initator, 0.5～2 part of promoter.
Fiberglass radome with the modification of peroxidating isobutyl methyl ketone of the present invention, its further technical scheme is that described initator is peroxidating isobutyl methyl ketone.
Fiberglass radome with the modification of peroxidating isobutyl methyl ketone of the present invention, its further technical scheme can also be in described resin formula material raw material, to also have the pigment paste of 2～4 parts, and pigment paste can make product have different colors to meet the demand of different clients to product.
The preparation method of the fiberglass radome with the modification of peroxidating isobutyl methyl ketone of the present invention, the conditional parameter of its expressing technique is as follows: 115 ℃, 1st district of heating, 150 ℃, 2nd district of heating, 130 ℃, 3rd district of heating, 140 ℃, 4th district of heating, clamping in advance opening time 2s, alternately triggered time 4s, interval time 30s, time out 10s air pressure 550kpa, hauling speed 300mm/min.
Compared with prior art the invention has the beneficial effects as follows:
In fiberglass radome with the modification of peroxidating isobutyl methyl ketone of the present invention, initator and accelerator combination can improve reaction rate, increase the extent of reaction, but consumption is less, Main Function: the one, as the curing agent of resin, improve the extent of reaction of goods, improve the styrene extent of reaction, reduce the residual quantity of styrene in goods; The 2nd, form binding system together with other auxiliary agent, the bonding of unsaturated polyester and fiber and other material played an important role.
Fiberglass radome smell of the present invention is low, and in product, styrene can be reduced to 3.01mg/g; The mechanical performances such as hot strength of product do not reduce yet simultaneously, can reach user's the standard that requires, and reduce by 40% through its cost of material of measuring and calculating than methyl ethyl ketone peroxide as initator simultaneously.Preparation method is simple in addition, and finished product rate is high.
