Embodiment 1

[0044] A mineral composite fence described in this embodiment and its preparation method are made from the following raw materials in parts by weight: 40 parts of resin, 60 parts of mineral waste, 5 parts of waste fiber, 2 parts of heat stabilizer, 1 part of plasticizer, 1.2 parts of lubricant. The mineral waste is granite saw mud, and the waste fiber is waste spinning fiber. The preparation method is as follows:

[0045] Step (1): grind the granite saw mud to about 20 μm by jet mill, and then dry it in an oven;

[0046]Step (2): mixing the heat stabilizer, plasticizer and lubricant in a high-speed mixer to obtain an additive mixture;

[0047] Step (3): mixing resin, waste fiber, granite sawing mud and the additive mixture prepared in step (2) in a high-speed mixer, and then mixing in a low-speed mixer to obtain a mixture;

[0048] Step (4): The mixture obtained in step (3) is sucked into the hopper of the conical twin-screw extruder of the main engine through the vacuum fe...

Abstract

The invention provides a mineral composite fence and a preparation method thereof, and relates to the technical field of building materials, specifically, mineral waste replaces traditional calcium carbonate to serve as a filler to be added into a resin matrix, and under the synergistic effect of the mineral waste and other components such as waste fibers, the mechanical property and heat resistance of the composite fence are improved, and the service life is prolonged; and meanwhile, the utilization rate of mineral waste is increased, the production cost is reduced, the mineral composite fence prepared by adopting the scheme can directly replace wood, and damage to the environment is reduced. In addition, the material is simple, easy to purchase and low in cost, and the preparation method has the effects of being simple and low in energy consumption. The prepared mineral composite fence has good performance, the tensile strength ranges from 52 MPa to 67 MPa, the bending strength ranges from 52 MPa to 71 MPa, the notched cantilever impact strength ranges from 3.9 kJ / m < 2 > to 5.7 kJ / m < 2 >, the QUV accelerated aging time ranges from 2500 h, the color difference value E ranges from 0.3 to 1.6, the Vicat softening point temperature ranges from 81 DEG C to 89 DEG C, and the density ranges from 1.48 g / cm < 3 > to 1.67 g / cm < 3 >.

Description

technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a mineral composite fence. The invention also provides a method for preparing a mineral composite fence suitable for industrial production. Background technique [0002] With the progress of society and the continuous improvement of people's living standards, various buildings, villas, and parks are further improving their visual effects and sensory experience. More and more places prefer to use fences instead of traditional walls to improve aesthetics and Ventilation, so the engineering demand for fence products is increasing. Therefore, the demand for fences, especially wooden fences, as the main fence species has increased greatly, and the supply is almost in short supply. [0003] However, as we all know, the poor durability of wooden fences leads to excessive maintenance costs, requiring a lot of manpower and financial resources to repair and reinforce...
