Abstract
The invention discloses a formula and production process of a glass fiber-reinforced plastic composite material. The production process comprises the following steps: a) impregnating: firstly mixing 10-20% of calcium carbonate and 10-20% of unsaturated polyester resin to obtain resin glue solution, placing the resin glue solution in a material trough, then feeding 65-75% of glass fiber yarns and/or glass fiber felt into the material trough from a creel in a manner that each fiber corresponds to one hole, thus ensuring adequate impregnation, wherein the lateral strength is improved by adoption of thick felt and one-way felt process; 2) preforming: guiding the impregnated fiberglass yarn and/or glass fiber felt into a preforming area by a performing guide mold and preforming; 3) carrying out heating curing, wherein full wrapped three-stage electric heating is carried out in a heat curing zone; and 4) drawing and cooling. According to the formula and the production process of the glass fiber-reinforced plastic composite material, by a reasonable formula system and the production process, the degree of cure of the resin system is increased to improve the strength of the product and thus a series of requirements of a cooling tower structural frame, such as requirement on the strength, are met.

Wherein preferably comprise by weight percentage glass fiber yarn and/or glass mat 70%, water-ground limestone 15%, unsaturated polyester resin 15%.
Glass fiber reinforced plastics composite material formula of the present invention, has increased the proportion that glass fibre strengthens system, has improved product strength.
The present invention also provides a kind of glass fiber reinforced plastics composite material production technique, comprises the following steps:
1) dipping: first the water-ground limestone of 10-20% and 10-20% unsaturated polyester resin are mixed into resin adhesive liquid, and resin adhesive liquid is placed in hopper, then 65-75% glass fiber yarn and/or glass mat are entered to hopper by one hole of creel, guarantee fully to soak into, and adopt thick felt and unidirectional felt technique, improve transverse strength;
2) premolding: the glass fiber yarn after dipping and/or glass mat import mould by premolding and import pre-forming area, carry out premolding;
3) be heating and curing: behind pre-forming area, enter heated cure zone, heated cure zone adopts the electrically heated of full parcel syllogic, and first section of temperature is 100-120 ℃, and two sections of temperature are 120-150 ℃, three sections of temperature are 160-180 ℃, and whole process set time is 1.5-2.0min;
4) draw cooling: from solidifying heating zone, draw out by towing mechanism, centre arranges cooling section, and pulling speed is according to section bar size, shape adjustments, normal velocity range 30-60CM/min.
As a further improvement on the present invention, premolding imports mould and at section bar corner place, adopts outside small arc-shaped, inner great circle arc transition.Hollow square tube and channel steel type timber die are reasonable in design, the outside small arc-shaped that adopts at section bar corner place, and inner great circle arc transition, increases corner's thickness, improves product weak part intensity.
Premolding imports the reasonable in design, practical of mould, accurately leads, and can reject material unnecessary on glass.The electrically heated temperature of heated cure zone syllogic, can adjust according to envrionment temperature.Pulling speed, according to section bar size, shape adjustments, makes products solidifying abundant.
The present invention's glass fiber reinforced plastics composite material production technique also, have that production efficiency is high, technique is easy to the advantages such as control, constant product quality, also have that high-level efficiency, power consumption are low, the little feature of contaminative, by the dipping of resin adhesive liquid, bonding and moulding process, finally formed the section bar with certain textural property.
Glass fiber reinforced plastics composite material of the present invention is for the production of the structural framing of cooling tower, adopt unsaturated polyester resin and other subsidiary material as curing system, use glass fiber yarn and/or glass mat as strongthener, production high-performance compounded linear material, by rational formula system and production technique, improve the degree of cure of resin system to improve the intensity of product, thereby meet a series of requirements such as intensity of cooling tower structure framework.
Accompanying drawing explanation
Fig. 1 is that premolding of the present invention imports mould at the structural representation at section bar corner place.
