に用いられる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for preparing a spray-up molding resin used for molding products such as boats, toilet tanks, bathtubs, and tank linings. It is ideal as a resin for spray-up molding because it has little sag and can be easily impregnated and defoamed. -The spray-up molding method uses unsaturated polyester resin containing an accelerator and a polymerization initiator. Each pot is sent to a sho spray gun, and immediately after injection, both are mixed uniformly, and before being sprayed on the mold, the roving is mixed with the chopped strands cut with a cutter and sprayed on the mold. It will be done. Next, the liquid unsaturated polyester resin containing nine chopped strands is sprayed onto the mold and is rolled to blend the chopped strands and unsaturated polyester resin onto the mold surface, and the chopped strands and unsaturated polyester resin are mixed together. The mixture is blended and further defoaming is performed. ■After curing the resin at room temperature or by heating,
This is a method of molding glass fiber-reinforced resin products through a step of removing the product from a mold, and is used for molding toilet tanks, boats, etc.

て製品と表らない問題点がある(比較例1参照)。Compared to the hand lay-up molding method, this molding method can mold products with more complex shapes, and because it uses inexpensive roving yarn as the glass base material, it has the advantage of lower material costs for the product. For example, when molding a product with an upright body, such as a toilet tank, the volume is 0.0, which has the disadvantage of difficult process control.
For small products of 7 d, spraying requires 3 to 10 steps.
5-15 minutes, gel time 10-30 minutes
When molding a large product such as a toilet tank for 80 people, which has a volume of 6 mm, using a resin that did not cause problems with resin sagging or defoaming under the molding conditions of 1 minute, the molding conditions would be different from spraying. Since the work is changed to 20-35 minutes, rolling time is 20-40 minutes, and gelling time is 40-80 minutes, the resin sprayed on the upright part of the mold leaves the strand and drips from the mold. However, there are some problems that are not apparent in the product (see Comparative Example 1).

It is possible to add a thixotropic agent such as polymerized atk oil to the resin, but if the thixotropic agent is simply added to the resin, the rollability of the resin will be slightly improved, but a product that is sufficient for practical use will be obtained. In view of these drawbacks, Misaki, the inventor of the present invention, has attempted to impregnate glass fibers with a certain amount of resin and remove bubbles, and furthermore, no improvement in resin sag can be expected. When the resin was prepared, the resin solution was obtained by mixing a slurry-like unsaturated polyester resin solution containing a thixotropic agent with a paste-like unsaturated polyester resin containing silica gel, which is a thixotropic agent, without any dripping. discovered that rolling was easy, and completed the present invention.

Examples include aluminum stearate, zinc stearate, polymerized TB polymer, and oil. Among these, it is preferable to use 03) silica gel, which is a liquid modification agent, in order to prevent uneven hue from occurring in the obtained product. However, when a pigment is blended, other thixotropic agents may be used since they are hidden. Examples of hardening accelerators include cobalt octylate, cobalt naphthenate, manganese octylate, and the like. Examples of polymerization inhibitors include hydroquinone, benzoquinone, and p-1-butylcatechol. Examples of pigments include carbon black, titanium oxide, barium sulfate, cadmium yellow, and amber.

The thixotropic agent is blended in an amount of 0.3 to 2% by weight in the solid liquid to prevent sagging during blowing and to facilitate rolling operations.

Preferably, it is a liquid material which exhibits a state in which fine particles of (8) liquid are dispersed in a solid liquid. (6) It is presumed that the reason why the liquid is dispersed in the solid-liquid is due to the large viscosity difference between the solid-liquid and the liquid (B). This liquid resin is sent from the storage tank to the spray gun using a bong. The mixture is mixed in a mist with a polymerization initiator diluted with a solvent such as dimethyl 7-thalate or dibutyl phthalate, and the chopped strands 1 are also mixed in the middle and sprayed onto the mold. Glass fiber-containing unsaturated polyester resin is sprayed onto the mold using a spray gun until the required thickness is achieved, and then rolled onto mohair rolls, metal rolls, etc. to improve blending with the mold. Improves resin impregnation into glass fibers and defoams.

る。The reason why the resin prepared by implementing the present invention prevents resin sagging during spray-up molding and rolls well is unknown, but solid-liquid resins are better at impregnating glass fibers. Since the rollability is good, the number of rolls contributes to the improvement in the number of rolls, and the number of times of papermaking is increased by the resin sagging prevention line (6) liquid, and the dispersed particles of the liquid (6) are hardened with glass fibers. It is assumed that this is because the resin in the liquid acts like a binder.The present invention will be explained in more detail with reference to Examples.In addition, unless otherwise specified, parts and cells in the examples are based on weight.
