Problems solved by technology

[0003] The color or pattern of the current FRP surface is single, which is difficult to meet the diverse needs of users when using it. In order to make it have beautiful textures, wood can only be added to the outer surface of FRP by painting or transfer printing. The pattern made in this way is easy to fall off, and it will affect other mechanical properties of FRP. In addition, most of the current FRP boards are made of hand-made molds, which has low production efficiency and large loss of raw materials, which can no longer meet the needs of the market.

Abstract

The invention discloses continuously-formed wood grain glass fiber reinforced plastic and a preparation process thereof, and belongs to the technical field of glass fiber reinforced plastic production.The continuously-formed wood grain glass fiber reinforced plastic comprises a base body layer and a gel coat layer arranged on the surface of the base body layer, a reinforcing layer is arranged at the bottom of the base body layer, and a wood grain layer is arranged on the surface of the gel coat layer; and the base body layer comprises the following raw materials in parts by weight: 100 parts of unsaturated resin, 5-10 parts of a curing agent and 2-3 parts of an accelerant, and the gel coat layer comprises the following raw materials in parts by weight: 100 parts of unsaturated resin, 10 parts of flexible unsaturated resin, 0.3-0.5 part of an ultraviolet light absorber, 5-10 parts of a curing agent and 1-3 parts of an accelerant. The strength, weather resistance, yellowing resistance and the like of a glass fiber reinforced plastic product are not affected while the glass fiber reinforced plastic has various pattern structures, and the glass fiber reinforced plastic has high practical value.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastic production, in particular to a continuously formed wood-grain glass fiber reinforced plastic and a preparation process thereof. Background technique [0002] The scientific name of FRP is glass fiber reinforced plastic. It is a composite material that uses glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as a reinforcing material and synthetic resin as a matrix material. With its unique strong corrosion resistance, smooth inner surface, low transportation energy consumption, long service life, convenient transportation and installation, no maintenance and low comprehensive cost, etc. It has been widely used in drainage, factory sewage treatment, seawater desalination, gas transmission and other industries. With the development of industry, the continuous improvement of science and technology, and the continuous expansion of the application of FRP, people's...
