Preparation method of acrylic resin-based glass fiber reinforced plastic

Abstract

The invention discloses a preparation method of acrylic resin-based glass fiber reinforced plastic, comprising the following steps of: pultruding 100 percent of acrylic resin, 150-200 percent of powdery aluminum hydroxide, 5-30 percent of carbon dust, 0.3-2.5 percent of benzoyl peroxide, 0.2-5 percent of polyethylene glycol and 0.5-6 percent of stearic acid or stearic acid salt by a pultrusion process; feeding the materials into a process tank; and continuously forming by using glass fiber yarn as a vector and a die for heating in three-section areas to obtain the acrylic resin-based glass fiber reinforced plastic. The acrylic resin-based glass fiber reinforced plastic has high combustion property and an oxygen index up to 70; in addition, after 150 parts of aluminum hydroxide and 5-30 parts of carbon dust are filled, the acrylic resin-based glass fiber reinforced plastic keeps high comprehensive mechanical properties, longitudinal stretching strength as high as 500MPa, longitudinal bending strength as high as 400MPa and elastic modulus up to 25.5GPa.

Description

technical field [0001] The invention relates to a resin-based glass fiber reinforced plastic and a preparation method thereof. technical background [0002] The three major synthetic material industries of plastics, rubber and chemical fiber have achieved rapid development. [0003] The field has replaced some products made of traditional natural resources, such as chemical building materials used in construction to replace many traditional steel materials, and plastic processed products and organic polymer materials have also been widely used in transportation, electrical appliances, communications and other fields application. However, the flammability of these three major synthetic materials has also brought huge safety hazards to the whole society and has become a social issue that has attracted much attention. Therefore, increasing their flame retardancy and minimizing their flammability levels has become an important topic for researchers in relevant scientific resea...
