preparation example Construction

[0047] In the preparation method provided by the second aspect of the present disclosure, aeolian sand and fly ash are blended and compounded as filler, and then copolymerized with resin to prepare a new environmentally friendly ecological sand-plastic composite material. The key problem in the compounding of aeolian sand and resin matrix is ​​the interfacial bonding. Directly adding aeolian sand to the resin has only simple mechanical bonding, and the strength of the obtained product cannot meet the requirements for use. This disclosure adopts the method of binary composite filler, first compounding the aeolian sand and fly ash, so that the aeolian sand particles are embedded in the porous structure of fly ash to form a composite inorganic filler, and then carry out a copolymerization reaction with the resin to coat Strong chemical bonds can be formed between the aeolian sand particles of fly ash and the resin, and the coexistence of chemical bonds and mechanical bonds can imp...

Embodiment 1

[0065](1) Take 58 kg of aeolian sand, add 40 kg of water to the continuous scrubbing and desilting machine for scrubbing, and scrub for 20 minutes, then dry the scrubbed aeolian sand at 100-200°C for 20 minutes, and dry the dried sand The water content of the aeolian sand is 0.5% by weight, and then sieved to obtain 6 kg of the first aeolian sand with a particle size of 20-40 mesh and 48 kg of the second aeolian sand with a particle size of 100-200 mesh.

[0066] (2) Take 25 kg of fly ash, sieve and dry at 100-200° C. for 20 minutes to obtain 20 kg of pretreated fly ash with a particle size of 600 mesh and a water content of 0.6% by weight.

[0067] (3) Put the first aeolian sand obtained in step (1) and the second aeolian sand and the pretreated fly ash obtained in step (2) into a high mixer, and mix them at 50°C After 30 minutes, the aeolian sand particles coated with fly ash were obtained.

[0068] (4) 1kg of cross-linking modifier aluminate coupling agent, 0.5kg of intern...

Embodiment 2

[0072] (1) Take 110 kg of aeolian sand, add 60 kg of water to the continuous scrubbing and desilting machine for scrubbing, and scrub for 30 minutes, then dry the scrubbed aeolian sand at 150-180°C for 20 minutes, and dry The water content of the aeolian sand is 0.6% by weight, and then sieved to obtain 5 kg of the first aeolian sand with a particle size of 20-40 mesh and 95 kg of the second aeolian sand with a particle size of 100-200 mesh.

[0073] (2) Take 30 kg of fly ash, sieve and dry at 180° C. for 20 minutes to obtain 28 kg of pretreated fly ash with a particle size of 600 mesh and a water content of 0.9% by weight.

[0074] (3) Put the first aeolian sand obtained in step (1) and the second aeolian sand and the pretreated fly ash obtained in step (2) into a high mixer, and mix them at 110°C After 10 minutes, aeolian sand particles coated with fly ash were obtained.

Abstract

The invention discloses and relates to an ecological sand plastic composite composition, a method for preparing the ecological sand plastic composite, and a prepared material. The composition comprises aeolian sand, a resin and flyash; 100 parts by weight of aeolian sand is taken as a standard, the content of flyash is 12-80 parts by weight, and the content of the resin is 12-80 parts by weight. The disclosed ecological sand plastic composite is chemical in physical and chemical properties, is non-toxic and tasteless, is low in temperature sensitivity, produces wood texture after the surface treatment, is high in biofidelity, can completely or partially replace the conventional wood plastic composite profile and log, and has the properties of secondary processing of sawing, nailing, cutting or fixing through a screw, and a leftover material or a waste product can be recycled, broken, extruded again and set to manufacture a profile product.

Description

technical field [0001] The present disclosure relates to the field of building materials, in particular, to an ecological sand-plastic composite material composition, a method for preparing the ecological sand-plastic composite material, and the prepared material. Background technique [0002] At present, most of the profiles and panels used in municipal gardens, building materials, home furnishing, environmental decoration and related industries are logs or wood-plastic composite materials. unstable. In addition, both wood-plastic materials and logs consume a large amount of forest resources, which is not conducive to sustainable development. Contents of the invention [0003] The purpose of this disclosure is to provide an ecological sand-plastic composite material composition, a method for preparing an ecological sand-plastic composite material, and the prepared ecological sand-plastic composite material. The physical and chemical properties of the ecological sand-plas...
