Problems solved by technology

[0009] The objects molded with the above materials have the following disadvantages: one is hard to the touch and feels cold.
Second, poor surface adhesion
That is, painting or painting on its surface or pasting materials such as gold and silver foil, the adhesion is poor
The third is that the surface of the molded object is prone to cracking, and the paint film is blistered due to moisture and drying, and the appearance quality is seriously damaged.

Embodiment 1

[0017] The body shape art chair designed by me has obtained the patent right of appearance design, and the patent number is ZL200330108986.7

[0018] The chair is now molded from the material of the present invention. The specific formula is: the unsaturated polyester resin is 30% of the total amount, the cobalt naphthenate solution and methyl ethyl ketone peroxide are each 1% of the unsaturated polyester resin, and the cobalt naphthenate solution is added to the unsaturated polyester resin. After mixing thoroughly, add birch powder which is 70% of the total amount, after mixing thoroughly, take out a part and put it into a small container, add methyl ethyl ketone peroxide equivalent to this part, mix thoroughly and then use it.

[0019] When processing human body art chairs, 1. First paint the above materials on the mold, that is, first coat the second layer in the mold. These two layers are actually the second layer on the surface of the chair, and then paste the fine fiber ...

Embodiment 2

[0021] A large dining table with a swan base, the legs of the swan are molded using the material of the present invention. Due to the high load-bearing requirements of the leg, its surface does not need to be in direct contact with the human body, and its surface needs to be foiled and painted. For this, the following formula is adopted: 30% of unsaturated polyester resin, 40% of marble powder, 30% of wood powder, cobalt naphthenate liquid and methyl ethyl ketone peroxide are each 1% of unsaturated polyester resin, and the results of use fully show the new Pros of the formula.

Abstract

The technique for molding material prepared by unsaturated polyester resin mixed with silica powder by solidifying relates to adding wood powder to decrease the quantity of silica powder even replacing totally though mixing better. Compared with existing technique, the product is fit to furniture, handicraft, sculpture, household goods, food container, dishware and device in vehicle, and overcomesthe shortcomings of existing material.

Description

Technical field: [0001] The invention relates to a material that can be used for molding objects, in particular to a technology for making molding materials with unsaturated polyester resin and stone powder as main ingredients and under the action of an accelerator and a curing initiator. Background technique: [0002] Now, there are a variety of gorgeous handicrafts displayed in the store. The complex shapes, smooth lines, and exquisite carvings are breathtaking. The sculptures of figures, animals, and flowers standing in squares, communities, and even courtyards are lifelike and lifelike. Most of these handicrafts are not taken from natural materials, and most of these sculptures are not made of copper. They are made of unsaturated polyester resin and stone powder under the action of accelerator cobalt naphthenate liquid and curing initiator methyl ethyl ketone peroxide made. The specific process is divided into two steps. The first is to prepare the molding material, an...
